Natural language understanding and knowledge mapping technology behind smart speakers

This article is based on the sharing of Xie Dianxia, ​​the founder and CEO of Haizhi Intelligence. Xie Dianxia has many years of experience in word processing, knowledge management technology and management. He founded Haizhi Intelligence and led the team to develop the first Chinese personalized chat robot open technology platform.

The following is the sharing of Xie Dianxia:

Hello everyone, I am very happy to share with you this evening. The first few people explained the AI ​​and industry-related knowledge from different angles. I will start with a specific "smart speaker" product, and talk about how many new possibilities can be given to the traditional products of the speaker with the support of artificial intelligence technology. Sex, and what a new experience can ultimately be brought to the user.

What is the quality of a smart speaker?

I remember when I talked about smart speakers last year, everyone sees the wise and sees wisdom, and the opinions are different. Even the heads of some traditional Bluetooth or wireless speaker manufacturers in Guangzhou and Shenzhen believe that it is a smart speaker that can connect to a smart phone via Bluetooth or wifi. I think that the real smart speaker should be based on voice as the main interactive means. With the speaker as the medium, it can open up a lot of content, can listen, speak, understand you, and connect with the service resources. This is the real smart. Smart speaker. But from last year to the first half of this year, suspicion is the mainstream: Is this a reliable thing? Will everyone in this kind of speaker pay for it?

Until recently, Amazon Echo's smart speakers began to spread in North America, with sales exceeding 5 million units. Google is also following the pace of Amazon, launching a similar smart speaker called Allo. As an important entry point to the life scene, the smart speaker is no longer just a concept, it is already a future. I saw in Silicon Valley that Echo has become a common household appliance in many friends' homes and has become a new member of the family. Rather than other smart products such as glasses, watches, etc., more are geek toys, ordinary users throw into the drawer for a while, or just as a traditional product. There is no essential difference between smart products and traditional products. Some people say that Echo is similar to the status of the iPhone in the era of smartphones. The era of smart speakers is here!

On the other hand, several smart speakers in China, from the current results, no product like Echo has become a new member of the family, gaining existence and producing sustainable value. why? We can look at three aspects:

Speaker quality. After I got Echo last year, I talked with Shenzhen speaker professionals. They were amazed at their sound quality and hardware quality. Echo, which is more than one hundred US dollars, is a good speaker even if it removes the intelligent component. It has certain comparability compared with the bluetooth speaker of the same price. Our unsuccessful Chinese smart speakers are slightly different from the bluetooth speakers at the same price and are not competitive enough. Therefore, the smart speaker must first make the quality of the speaker itself.

The speaker is smart. The speaker is intelligent, at least able to communicate with people in the natural language of the person, to understand the meaning of the person, and to give the desired content. In the past two years, speech recognition technology has advanced by leaps and bounds, but everyone is well aware of it; but in terms of semantic understanding, it is indeed a challenge. In contrast, Echo has achieved certain usability in the field of providing services in the process of communicating with users. The pioneers of Chinese smart speakers may have good Chinese speech recognition, but the semantic analysis link is weak. The end user's overall experience creates a bottleneck.

Content resources. Sound quality and interactive experience are guaranteed, not enough. When the user speaks, the smart speaker understands, and the best way to make the user cool is to directly give the user the desired result. For example, if the song is clicked, the song will be played directly, and the crosstalk will be played directly. The intelligent product of voice interaction as media is different from the product with webpage and app class interface. It has no content range that does not have any interface to limit the user's question. When people interact with the speaker, there is almost no explicit boundary. In this case, the content is required to have quality, and the second is to have a volume, understand and cover what the user wants. Similarly, Echo combines the music library of Amazon's own resources, and accesses third-party resources such as Pandora and Spotify, and has a considerable size. Experienced echo will find that in the field of service it provides, the experience is guaranteed; in the area that has not been covered, the robot Alexa in the smart speaker will tell you "I'm sorry, I don't have this service". The pioneers of our Chinese smart speaker products may have a wide variety of fields, but the quality and volume of the content needs to be improved.

Of course, the factors affecting the quality of smart speakers are not limited to these three aspects, but the above three aspects largely determine the overall user experience of a smart speaker. How to improve the sound quality as a speaker is not the focus of today's discussion. The latter two parts, especially semantic understanding and resource integration, we have relatively understood, tried and accumulated experience, even at the same time facing challenges. .
