Science and Technology News on November 16th, Baidu's general manager of the business department, Jing Hao, announced at the Baidu World Congress in 2017 that DuerOS2.0 is officially open to the industry. On the same day, Baidu also released three artificial intelligence hardware products equipped with DuerOS2.0, Raven raven H, raven R and raven Q.
Jing Hao said that as an Android in the era of artificial intelligence, DuerOS is everywhere. In the era of artificial intelligence, the human-computer interaction method is still changing. The AI ​​operating system needs continuous learning and evolution. The comprehensive upgrade of DuerOS from 1.0 to 2.0 will bring better “listening, understanding and satisfaction†to users and the industry. Experience.
In order to better awaken all things, the small intelligent device open platform has been comprehensively upgraded in terms of technical capabilities, solutions and platform systems.
Upgrades in technical capabilities, including voice wake-up capabilities, voice recognition capabilities, synthetic voice, and AI capabilities.
Solution upgrades, including better far-field voice interaction development kits, updated voice-interactive APP solutions, updated DuerOS for Apollo solutions, and updated cross-scenario cross-device solutions; platform architecture upgrades, including new IoT equipment cloud, smart device quality certification support, platform system is more abundant.
At the same time, DuerOS not only greatly improved the richness of the native skills and user experience, but also released a small skill open platform. The small skill open platform will be open to content, smart home and life service partners, and open up Baidu's core AI capabilities such as natural language understanding, knowledge map and system intent. DuerOS's skill ecosystem currently has more than 200 skills.
Guan Yusong, Dean of Baidu Artificial Intelligence Interactive Design Institute, announced the establishment of the Artificial Intelligence Interactive Design Institute on the spot. The design institute will help DuerOS partners and global AI products to continuously improve and optimize their interaction design in the form of report output and product evaluation.
At the same time, the Prometheus Plan has also officially set sail. The plan includes the opening of ultra-large-scale dialogue AI data sets, interdisciplinary cooperation, etc., and will also use a $1 million fund to encourage and foster excellence in the field of conversational AI. Projects and talents.
After the meeting, Jing Hao accepted an exclusive interview with the media. In an interview, he said that at present, people don’t feel much about human-computer interaction in real life, but human-computer interaction is a more natural way. Baidu is very confident, we need to give This industry is a little patient.
In the interview, some media asked about the difficulty of the artificial intelligence operating system. Jing Wei believes that Baidu is the only cooperation module that has resources, technical reserves, knowing the challenges between each module, and how to integrate third-party cooperation modules. Even in some scenarios, only Baidu is doing this module. it is good. Jing Hao believes that as an operating system, the company's genes are also important. He believes that Baidu is the only one that really has the opportunity to make this thing, and from Baidu's current progress, it is not bad. (spa)
The following is the full text of the interview shorthand:
Jing Hao: Hello everyone, I am Jing Hao. Many of my friends have met several times. They are very familiar. Everyone in the circle of friends has seen me a lot of information. I am responsible for the Baidu DuerOS platform.
Moderator: If you have any questions, you can ask questions.
Question: I am a media from Shenzhen focusing on intelligent hardware. When we as reporters, the form of practical human-computer interaction is relatively fast, but how many ordinary people actually have such a way to talk with machines? The scenes we see are more in the car, the speakers in the house, and other parts, including so many of our equipment, how many people are actually using it. Is this interactive form mature? What kind of plans does DuerOS have in this regard?
Jing Wei: I think that when any new generation of interactions emerges, from the original keyboard, mouse, to the later touch screen, resistive screen, capacitive screen, this interactive change is not immediately changed. If you look at the popularity of the entire smartphone, iPhone4 will appear in China, and it will begin to be truly popular. At this time, we need to give the industry a little patience. First of all, this voice interaction is more convenient and more natural in some scenarios. As you just said, in the car scene or the home scene, sometimes in a scene like a headset, and sometimes in the scene of a mobile phone, the phone is placed inside the car, I think it is a more natural Interaction. So we need to give this interaction more confidence. This kind of interactive change requires a big platform like Baidu to promote. Because such changes often require more resources and the power of capital. So the OS is at the forefront of the times, and we push it forward. When it comes to how to accept the people, I think the overall experience is very important. The whole experience of voice interaction is not only the wake-up of voice interaction, but also the end-to-end experience of the whole product's face value and sound. These are all important factors that drive people to accept the product experience of voice interaction.
We work internally with many partners, so we can see a lot of data. The data we see is very positive. Many users are able to develop some habits after accepting this new smart device, from the original curiosity to the use of some fixed scenes every day. This is also the signal we see after many companies have spared no effort to push this direction. So from our point of view, I think it is very confident, it is very positive, users are accepting this new interaction.
Question: I am from Sohu Technology. This morning, Robin talked about the natural language interaction of keyword-free. I have also learned about similar solutions from other vendors. I think that if the product uses keywords, it may be relatively private. If there is no keyword, it is possible to identify the words that are usually spoken and upload them to the cloud, and then pass them down to understand, how to protect privacy issues? Another problem is that some vendors now have a full-stack voice open platform. How does DuerOS view this? Is there a plan in the future?
Jing Wei: I think these two questions are very good. The first question, privacy issues are particularly critical, and many media friends may be concerned. I explained a bit, Robin's demo, he has some details, I don't know if you are concerned about it. He wears a headset, and our natural language interaction on the phone is now based on the need to wear a headset, which is a very personal device. In addition, he is using a special mode of mobile phone Baidu, which is the mode of listening to news. If you download the mobile phone Baidu 9.0, this mode is to open the news first, then the APP will prompt you, has started listening to you. Then I will remind you that it is better to wear headphones. This wake-up call is currently an experience like this. It's not a device at home, it's always listening to users.
Question: Or similar to that kind of smart speaker.
Jing Hao: Smart speakers are not used yet, because the privacy of smart speakers in the home scene and the privacy of different scenes need special handling. Therefore, this keyword-free device is currently used in conjunction with headphones in mobile apps, and there is no privacy issue. In terms of family privacy, in fact, everyone will have a lot of considerations. For example, it is common practice in the industry to wake it up first and then talk to it. At this time, there will be direct interaction with the cloud. You don't wake it up, this device has no interaction with the cloud. This is a question about privacy. The keyword-free keyword is implemented by Robin on a limited scene and a limited device.
I am particularly pleased with some of the companies that have developed voice kits. I am a very good friend with them, and sometimes talk privately in the circle of friends. I think that especially in the Chinese market, even in foreign markets, the people who promote it cannot be a family. If it is an industry, everyone will do it together. Just now I talked about production, learning, and research. It is best to push the industry, academia, and research together. This matter is going fast. So I always think that the healthiest time in the market is when everyone pushes forward. So I am very happy. Some other companies, including future partners, are all pushing together. I think this is a particularly good thing for the industry.
Question: Is there any corresponding plan? Will we also have a full stack of devices?
Jing Wei: One of the DuerOS I just mentioned, one of which is a better and more voice solution, so we will have a full-stack development kit that works with Sophi Technology. Why is this launched? We are all based on feedback from our partners. At the developer conference we introduced a separate speech recognition suite that was used with the Raspberry Pi. Some developers say that integration is better, so we will announce an integrated solution with Sophie this afternoon.
Question: We know that smart products that do a voice interaction require a lot of technical sections, such as signal noise reduction, speech recognition, etc., which require a lot of technology. Today we see a lot of technology is the use of, such as voice recognition with A manufacturers, but also with C manufacturers. However, there will be problems in patching together, such as a signal denoising and a company that performs speech recognition. The technical goal of the former may be to reduce noise and make the ears sound clear, but the mechanism of the ear is different from the machine, so In the latter case, the signal processing of the former is a black box. In the era of the Internet of Things, the complexity of making products is not an order of magnitude, and there will be tremendous friction when coupled between upstream and downstream. And there was a place that was blocked and all blocked. I also heard an industry voice, and the artificial intelligence industry is hard to see a real operating system in a short time. Because it is completely different, it cannot be standardized. Therefore, some people say that people who have been in the industry for a long time, they will mention end-to-end, they are difficult to be an operating system. So I want to be a representative of the operating system, how does DuerOS view this matter?
Jing Wei: First of all, I think your question is very good. In the future, the industry will definitely follow the standardization. Basically, any industry is the same. For example, the car industry has been developing for such a long time. You will also find that many components of Tesla are also purchased from others. They are put together and then polished end-to-end. It is not every part of Tesla. It is produced by itself, and its battery is not produced by itself. So I think that the whole industry will be standardized gradually. Different people are good at polishing a single module and optimize this module to the best. No company can really have resources. Every module is optimized to be an ecosystem. Cooperation, this is my view of the entire future of standardization.
Now our raven is the end-to-end solution. Why do you want to do the Raven? I think the product experience is the most important, and end-to-end may be better at some different modules. From the design to the noise reduction, the Ravens are all Baidu. But at this time, I think that artificial intelligence dialogue type human-computer interaction involves many scenes, such as headphones, speakers, TV, and car scenes. It is impossible for all the products of a company to be end-to-end. This resource is too big. So at this time, it is necessary to properly integrate the technology of the best technology companies in the industry. At this time, I think it is an opportunity for the operating system. Because you can't cover so many end-to-end, such as the company, he does a good job of identifying the entire voice microphone array, working with many big companies. From a technical point of view, we can find a clearer boundary, and at the same time unify the technical path of the user experience, which is not a technical route that can be realized completely end-to-end. At this time, do you say that you need an operating system? I think it is absolutely necessary, otherwise the user experience is not uniform. Many of the companies you see, small company operating systems are difficult to do, because there are too many different modules involved in the device partners. I think Baidu is the only cooperation module that has resources, technical reserves, knowing the challenges between each module, and how to integrate third-party cooperation modules. Even in some scenarios, only our module is doing well. I think the company's genes are also important as an operating system. I think Baidu is the only one that really has the opportunity to make this thing, and from the overall progress of our present, it is not bad.
Question: The morning raven debuts more than Robin and Lu Qi. What do you think about the sales of this product?
Jing Wei: I heard that their official website was exploding this afternoon. From my point of view, I am very optimistic. I will never question the purchasing power of the Chinese. If you do this well, you can play a certain market. Just like you are very Fashion, if you don't buy it, you won't have a Fashion, so you have to buy one. I think the Raven has its current smart hardware market. To be honest, I think it is now compared to mobile phones. It’s not that big. This market is a few orders of magnitude worse than mobile phones, so the market capacity is huge. There is this market capacity at any stage, not that he hits that stage, his sales will be challenged by other sales, and many still sell well. So I think it has its market. But I am not too concerned about its sales, we are internally concerned about an indicator called "net recommended value." This is the device you bought, you will not recommend it to your second friend. This is a very important indicator, this represents the product experience. As long as this value is high, everyone feels that this product is a good product, I think this purpose has been achieved. We don't have to give the iPhone a very ambitious goal for the first generation, but it is a benchmark for human-computer interaction. We have the first product, and this goal is already very good.
Question: I am a reporter of People's Daily. I just heard you speaking on the stage. After the developer conference, we have more partners. I would like to ask if there are any new partners in the four months to share with us. There are some millet, beauty, etc. on the screen. In addition to these relatively large ones, if there are some small startups or individual developers looking for them, what kind of cooperation will we adopt?
Jing Wei: First of all, we have a lot of personal developers. We probably did three offline activities around developers. The degree of anger is beyond our expectations, and there are basically 400 people in the 200-person field. So we see that the whole long tail, the enthusiasm of individual developers is particularly high. So our development kit, at the beginning we do the whole soft and hard combination. When we released on July 5th, we encountered a challenge, that is, our inventory was insufficient, and it took two months to satisfy this inventory. At first we didn't have such a big concept, but this is a signal that the enthusiasm of the developers is particularly high. Regarding our new partners, two new and very heavy-duty partners may be announced this month and next month. I will not say this, everyone is looking forward to it and is a very important partner.
This afternoon, because you first came up, we have several heavyweight partners announced. For example, this afternoon we announced a cooperation with Philips. They are the most popular smart home light bulb devices in foreign countries. DuerOS is the first to achieve strategic cooperation with them in this regard. This afternoon, we announced cooperation with China Merchants Bank Credit Card, which is a good commercial bank. If you download its app, you can find that its credit card service has been done very well. Our cooperation is the first strategic cooperation between the bank and the dialogue artificial intelligence interface. Wait a while and release a lot of strategic cooperation with other new vendors.
Question: Which field is more pre-emptive?
Jingwei: We divide our partners into several layers. On the first level, we hope to be the leader and industry leader in each category and every category. They have sound and potential energy, and they have a very accurate grasp of the industry. On the second level, we also have some medium and long tail partners who are very representative of the industry. These companies don't need to be big, but their products are valuable and everyone will stare at it. It may not be large, but it may represent a benchmark. Such a partner is a medium long tail. There are also individual developers and many solution providers. We also have a lot of cooperation, so we can't enumerate them one by one, especially many.
Question: I want to ask questions about my partners. Although today's new products are being promoted, DuerOS is also working with third-party application vendors on a large scale. As a later enabler, do you have any differences between your own and other hardware manufacturers?
Jing Hao: No difference. From my point of view, a metaphor we have been doing internally is the metaphor of Surface and Lenovo notebook. Why is Microsoft pushing Surface? It’s just speculation that because of the need for a new device, a combination of soft and hard devices, to drive the revolution of the entire notebook, so Microsoft made a Surface. Although the current amount is not large, but the entire notebook continues to move forward, is a very good experience equipment. For us too, the Raven is a benchmark user experience device. Just said, the technology behind all the raven this afternoon will be open to our partners. We talked at the developer conference that Baidu is going to be an AI platform. Baidu's current AI platform is also very stressful for us. We are doing the platform well. This is what we are pursuing, so we have to become an AI platform company.
Question: Just mentioned the technology behind the raven, I would like to ask, what is the core or most competitive technology of the technology behind the raven compared to other intelligent hardware manufacturers?
Jing Hao: In addition to the characteristics of the product itself, the technology related to DuerOS includes, for example, the Raven's microphone array, which uses 8 microphones, 4 covers on the top and 4 bases on the bottom. Like this new microphone array technology, it should basically be the first attempt in the industry. After the lid on the raven device is taken down, it can be held down and spoken, that is, it is near field. So this is a way of interacting between far-field and near-field fusion, which is also related to its device characteristics. There is also the polishing of music. After we basically upgrade the music, the whole music label has been done more. Made more than 7,000 application tags, allowing users to play any tag of music on this smart device. Coupled with our many new abilities, we just said below that we have more than 100 third-party skills that will be closely integrated with the Ravens device. Therefore, I think that the overall product characteristics of the Raven are soft and hard, and it is a comprehensive integration. From design to sound, to our technical capabilities, to the content behind, the whole package is a product with a good user experience.
Question: Now all the hardware equipped with DuerOS, from the background data, which type of product has the highest per capita interaction ratio?
Jing Hao: It's quite tall. I want to say which is the highest, the other is not happy, in fact, it is quite high.
Question: Just now you also mentioned that we have a lot of partners and hardware solutions. I want to know which scenes are the most grounded? And which products are you optimistic about?
Jing Wei: I can only start from our own point of view. Nowadays, there are many mobile phone partners on the market, and many of the voice interaction capabilities behind us are provided by us. Subtle, DuerOS is already behind many phones. In the scene of TV, we have basically cooperated with traditional smart TV manufacturers, OTT cable boxes, and radio and television boxes. There are also a lot of speakers. I just mentioned that there is a DOSS speaker. It was originally exported and was exported to foreign countries with the Alexa system. However, it was once sold on the domestic DuerOS system and has been sold on Amazon. We are working closely with Apollo, so basically we will cooperate with BAIC and FAW to equip the equipment of the DuerOS system. Others are even more dispersed, like wearables, headphones, and a little more scattered. A few big categories are those just mentioned.
Question: I would like to ask, according to the Baidu Developer Conference in July, a few months have passed. What changes have you made to the entire intelligent voice market in this pattern? Including from technology, players.
Jing Wei: First of all, I think that the past four months have been particularly rapid for four months. I didn't expect these four months to become so lively. After we released this platform on July 5, during the four months of the process, basically the Chinese companies have already launched similar things. So I feel very good about the development of this four months. From my point of view, I feel very happy. As a driver, many different people and different companies have joined the process to promote this change.
I personally feel that the real change of human-computer interaction will take a long time. It is not enough for four months, and it may take years. Now everyone is in the initial stage, all companies may be in their infancy, and many companies are joining the industry. Therefore, I hope that the whole industry can maintain this enthusiasm. Pushing this kind of human-computer interaction forward and pushing it to every family, it is a necessity.
Question: We all know that Baidu has a lot of target cooperation groups, from large companies to small individual developers. Enterprises will not say, for personal developers, what kind of help and support can Baidu provide? Let them develop better? And we used to like this relationship to be the same as iOS, Android for App developers. How can security and operability be ensured during the implementation process?
Jingwei: Does security mean privacy?
Question: Individual developers must use some privacy of the user. As Baidu, how can you guarantee this security?
Jing Wei: First of all, let me talk about why we want to develop individual developers? We really want to promote an industry that needs to be promoted from industry head manufacturers, small and medium-sized manufacturers and individual developers. In particular, we see a signal: Although an individual developer does not have many channels, its creativity is unlimited, it is particularly creative, and it can basically put his ability on different devices. Some time ago, a developer put the module of the voice dialogue on the Yan dance radio, and let the device rejuvenate. Yan Dance Company directly found Baidu. The original Yan Dance group is the group with the strongest consumption power today. DuerOS has made their company more energetic. Therefore, individual developers can contribute a lot of imagination to our ecology. It is a source and very meaningful. When it comes to privacy, I don't think it exists. Because personal devices that personal developers often develop are used by themselves. He does not have strong channel promotion capabilities and cannot promote to many people. He uses them all by himself.
Question: What kind of support and help can Baidu provide to such individual developers?
Jing Hao: For example, this afternoon's integrated development kit with voice is equivalent to providing a soft and hard integration solution for individual developers. We will also release our skill platform this afternoon. Developers can build their own skills in the cloud. With resources, capabilities and skills in the cloud, it will become his own end-to-end solution. Can be used, very good.
Question: When we often do voice interaction, we will press Hi, Siri, or Hi, small, or small, with a wake-up word. When I heard this introduction this morning, I don’t need this wake-up at the end of the month. How is this technology implemented?
Jing Wei: This is the same as the previous question. This technology is only in the scene of mobile phone Baidu, listening to the news mode, is free of wake-up words. Need to enter a specific mode of voice interaction, the other modes have not been applied.
Question: I am from 36Kr, we DuerOS has always stressed the need to be Android in the era of artificial intelligence. From an ecosystem perspective, which aspects do you think are more critical?
Jing Wei: I think the most important part now is the user experience. Especially when we have more partners, can we guarantee that each device can have a better and consistent user experience? This is more critical for us. Because at this time, it is best to achieve this effect: it allows the user to use any device equipped with DuerOS in different scenes, in which scenes are like this DuerOS-enabled device, and used to Always use this device. So I think the most important thing now is the whole user experience. Do you really buy a speaker and go back and use it? Can you understand what you say? Open the package, there is a person who has never used a smart speaker, what is this? You said that this is a smart speaker, you can be clear in one sentence, you can interact with this device in one sentence, I think this experience is the core of the current ecosystem, and our ecosystem must rely on a better experience to push forward.
Question: Just now they all said that we have to push a device without a wake-up word. I am very curious. We acquired a small team that made wake-up words at the developer conference. I want to know that they are in the 4 months. What kind of role is it responsible for? Why did we acquire such a small team that is a wake-up word, and now we are launching a technology without wake-up words?
Jing Hao: It is only in the environment of the mobile phone Baidu App, the reading mode is free of wake-up words. The wake-up words of smart devices that are not in the home environment can't be done, and there are some privacy issues. So just limit the scene, limit the human-computer interaction in the App. In the intelligent interaction of the home, the wake-up word is indispensable, because there is a certain privacy protection, first wake it up and then talk to it, before he wakes up, he does not interact with people. The company we acquired is called KITT.AI, which is a wake-up call for intelligent interaction in the smart home field. Many of our partners want to make their own wake-up words, including DuerOS-enabled speakers, refrigerators, and TVs, all of which need to be optimized for wake-up on the device. They often need to be optimized for the device. Because the distance of the microphone is different, the number of microphones is different, so special tuning of these devices is required to truly guarantee a good user experience. Through KITT.AI, we have pushed this technology to our partners and put them in their microphones to make them work better.
Question: The smart hardware we launched this time is equipped with the DuerOS system. What is the difference between the capabilities of other products launched with this system?
Jing Hao: It is the first to be equipped with DuerOS 2.0. DuerOS 2.0 implements all aspects of capability upgrades, and other devices are basically upgraded to DuerOS 2.0. The Raven is the first benchmark of DuerOS 2.0, and we will open up DuerOS 2.0 to our partners.
Question: I am from the heart of the machine. In the name DuerOS, I think OS should be the focus. Now all voice vendors have their own platforms. The model seems to be similar. I want to know, what is the difference between DuerOS and other homes in terms of business models, content models and models of their own technologies? For the two letters of the OS, I feel that there is a little blurring. If it is carried in a smart speaker, we interact with it, it is an OS. This kind of system in other homes is also equipped in the speaker to interact, why Duer can call OS?
Jing Wei: First of all, you mentioned the commercial technology ability. Commercialization is not our goal at present. I think it's most important to make the user experience right at a critical time. If the user experience is not done right, the business is white, and it may not be able to reach that step, so the user experience is the most important. Everyone is doing conversational AI, everyone is optimistic about this direction. On July 5th, I also said that the four largest companies on the technology map are doing conversational AI. When every company is doing it, it will basically follow the company that was good at it. It naturally becomes the biggest feature of this product, basically it can be seen like this. The DNA of each family is different. After each platform is made, it feels completely different. DuerOS is a platform to bring out Baidu's strongest capabilities, so Baidu is different from other platforms, and DuerOS is different. For example, some friends do a lot of speech recognition, just voice to text. The biggest market before Baidu was the Baidu search ecosystem. Baidu’s understanding of language is the biggest difference in Baidu. So Baidu's biggest difference is placed on DuerOS, which is the biggest difference between DuerOS. It is equivalent to DuerOS's interaction with the language. After understanding the language, you can also put more content and resources, as well as developers, and our developers are web developers and later app developers. So DuerOS becomes a window to access many of the resources of the original Baidu ecosystem platform. Therefore, DuerOS is a microcosm of Baidu's AI capabilities and resource sets. It is a microcosm of conversational artificial intelligence, so its biggest difference is that Baidu's potential is different from other companies. If you evaluate other people's platforms like this, you can get the same result. There is a microcosm of his entire company behind each platform. This is the biggest difference of this platform.
For the clear definition of OS, in fact, I originally proposed to call OS. My opinion on OS is that it is an ecosystem, an operating system. Behind the operating system is an ecology, a platform, not just a product of a speaker. It depends on the development of the business, whether to do something, or to make an ecology, and to promote development together on this platform. I think DuerOS represents our vision and OS should be an ecology. I would like to extend a little bit of the key point of an OS, not that it is called OS, or whether it has its own ecology. If he does not have his own ecology, it is not an OS. There are many OSs in the mobile age, and many OSs are called OSs, but later you discovered that it has no ecology of its own. All of your own ecology can be called OS, Android has its own ecology, can be called OS, Windows has its own ecology is OS, if you are attached to these platforms, you can not call OS, because you do not have your own platform. . So we DuerOS also hope that in the new mode of voice interaction, we can create our own ecology. This ecology is based on the ecology of new interactions, which is why we are named OS, which is an open and empowered platform ecosystem.
Question: Today, at the beginning of the promotional film, everyone said that this technology is based on Android or Linux. Is it wrong for me?
Jing Wei: You can think like this. The original systems are all from the previous generation. They are a low-level system, not so concerned about interaction. DuerOS is actually an operating system driven by user interaction. The mobile era is different from the original PC. The AI ​​technology is different from the original one, and the AI ​​equipment is also very different. In this diverse situation, what DuerOS has to do is to unite users through voice interaction. Although the devices are very different, they are all united with one interaction. This is the relationship that DuerOS wants to bind. Other OS I see it as our original system adaptation layer, adapted to the original traditional OS. But DuerOS is a platform for voice interaction, and more on the upper level.
Question: I just mentioned developers, similar to the concept of 100 Skills on DuerOS. Are these Skills contributed by developers or yourself?
Jing Wei: We have our own 100 natives. There are a lot of developers now, as our early adopters, they have built more than 100 third-party Skills on our platform.
Question: The original is 100, and there are 100 developers?
Jing Wei: Yes, third party.
Question: I am from the interface. When you work with vendors, do you know which metrics they value? Because I found that some manufacturers later changed Baidu's system, I don't know if there are any specific strategies? Android system to be a device, now which step has been taken, what do you think is worse?
Jing Wei: Equipment manufacturers are now most concerned about understanding and satisfaction. If the original core three elements are used: listening, understanding and satisfying, equipment manufacturers are most concerned about understanding and satisfying. Many smart speakers may feel a bit silly, the interaction is not so natural, ask it something it doesn't understand. So now this piece is the most concerned by our partners. In fact, this piece is the most concerned by the people. The common people don't care about these three modules. The people care most about me and ask you a word.
