At present, the concept of the most hot in the science and technology circle is not "artificial intelligence", and it seems that any product that does not relate to artificial intelligence will be eliminated by this era. Of course, smart TV is also within the scope of discussion. However, what few people can say about the Qing artificial intelligence can bring us anything. 
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
Artificial intelligence is abbreviated as AI. We do not need to go dogmatic to understand its definition. We only need to know that it can help the machine to communicate and interact with humans. Implemented on television, we can understand that artificial intelligence can let TV learn to listen to our voice instructions and make corresponding operations, such as a simple boot, shutdown, etc., belonging to the era of AI 1.0; able to do "semantic analysis" It is an advanced AI 2.0 era artificial intelligence TV that can understand and analyze the user semantics to achieve the functions of analysis and recommendation. This is the AI ​​3.0 referred to in our title.
It may be enough direct to say so. Let's use a few examples to help everyone understand. On December 20th, Changhong organized an “AI 3.0 Private Enjoyment Intelligence†Q5K Artificial Intelligence TV Trial held at the Commune by the Great Wall at Beijing’s Great Wall, gathering the latest and most representative TV products of the five traditional TV brands. From the TV user's real life scene, the four functional dimensions are measured, interpreting what is true AI 3.0, and let all the media present witness the charm of AI 3.0.
One, far-field voice
Why do you want to compete in far-field voice?
The most important function of artificial intelligence is to liberate manpower and increase efficiency. People do more complicated things because with artificial intelligence, it becomes simple and easy, and the saved manpower can do more things and create more value.
There is no need to say much about the convenience of voice interaction for human beings, but traditional voice interaction needs to be performed manually. For example, pressing and holding a remote controller to send voice commands has limitations in terms of convenience and speed.
At this time, the advantage of far-field speech recognition that truly enables “free hands†is reflected. TV built-in microphone array, users can touch any device without hands, by saying a specific "wake up words" to activate the far-field voice recognition function, you can within a certain range of pure voice control TV. The use is more convenient and the process is faster.
After testing, it was found that only Changhong Q5K has far-end speech capabilities among the five products, and the other four products currently do not support far-field speech recognition.
Just draw this conclusion, presumably can not satisfy everyone's curiosity! Where is the limit of far field recognition of artificial intelligence television? The test group used the same sound size to test the Changhong Q5K at the positions of 1m, 2m, 3m, 4m, and 5m, respectively. It was found that within 5 meters, Q5K's speech recognition is very accurate, and its application range is more than 5 meters.
Second, voiceprint recognition
With voiceprint recognition technology, TVs provide personalized visual and content services based on identified characters (eg, men, women, children). Unfortunately, the Changhong Q5K still has the ability to recognize voiceprints among the five TVs tested. The other four models do not have this capability.
Changhong Q5K supports multi-person voiceprint registration and role classification. It distinguishes the users who currently use the TV by the different voices of each person, and learns and analyzes the user's habit of using TV to achieve accurate content recommendation.
The male tester and the female tester respectively said “I want to watch a movie†to Changhong Q5K, and Q5K will present different visual effects and recommended videos based on the identification. The interface for women is soft pink, and the recommended film is mainly romance, while men will see dark blue vision, as well as some movements, science fiction-based video results. If you are a kid, you will get some cartoon recommendations.
For the user, this personalized service is very necessary, but from the current development of the television industry as a whole, the voiceprint recognition is not mature enough, and the technology application still needs a certain amount of time to polish.
Third, semantic understanding
1, music, film search
The most basic function test, said "I want to listen to "Chengdu" for the five TVs. Except for one TV, the other four TVs can give correct responses and find Zhao Lei's "Chengdu." Continuously on-demand 20 songs, including "just happened to meet you", "repair life", "Triangle" and so on.
The test team also put forward the requirements for watching movies. "I want to see "War Wolf 2", "I want to watch "Wrestling! Dad"" and "I want to see "Mental Psychology." This time, TVs such as Changhong Q5K have performed quite well and have significantly better content resources.
2, the local operation
For the basic operating instructions such as mute, set, return, and volume increase/decrease, the five TVs can basically be controlled by voice. However, the performance of Changhong Q5K is even better, it can support voice power-off, and the other four TVs cannot use voice to boot.
3. Oral instruction
Around the basic operation, the test team tried to change the saying "too bright" or "too dark" to see if the TV can understand. Changhong Q5K can recognize the user's intention "adjust brightness".
4, logic capabilities
Logical ability is a hot spot in the current artificial intelligence TV competition, which is mainly manifested in the understanding of the relationship between characters. In the test, I said to five machines that "I want to see her husband's movie" and "I want to see her husband's TV show." Changhong Q5K can accurately find Deng Chao's movies and Chen Xiao's TV series. The other three TVs have The results of the film and television dramas of Sun Yi and Chen Yuxi were given, while others were totally puzzling.
Based on the above four items, the accuracy of the semantic understanding of the five TVs in a typical usage scenario is as follows:
Fourth, fuzzy search
With voice as the carrier's interactive method, it is inevitable that there will be a problem of misinterpretation when speaking, and sometimes the user may send a missed tone promptly, sometimes it is easy to say wrong. Whether the TV has the self-correction capability and the user finds the correct audio and video content under the circumstances that the user's objective instruction is wrong or the machine itself has recognized the error is a competitive point that the test wants to test.
The testers intentionally said "You don't come to me" and confusedly said "I don't come to you is not good", and put "Wolf 2" into a "wolf 2", "wrestling!" Dad said "Wrestling", and mistakenly said that "flower blooms on that year" mistakenly stated that "flowers are being turned on." What is amazing is Changhong Q5K's performance. Whether it's a typo, a homonym, or a reduced character, it can be automatically corrected to find the correct content of the user's goal. To such a degree, the accumulation of data by Changhong artificial intelligence TV is by no means a success.
The experience of the other four televisions in this area has yet to be optimized.
to sum up
After the above four groups of comparative tests, we have clearly understood what AI 3.0 is and how advanced it is compared to the previous two generations of technology and can even enhance our experience in using TV.
However, this is not all that this comparison has to say. Because in the traditional impression of the traditional consumer, it seems that high-tech is linked to the internationalization of big brands, people always underestimate the performance of domestic brands in research and development.
It is worth mentioning that there is no lack of familiar “international big names†in the prototypes involved in this comparison. However, they not only failed to show performance compared to Changhong Q5K, but even lost to other domestic brands competing with Taiwan. The drawbacks such as slow development of research and development and ungrounded gas brought by the big brands are becoming increasingly prominent.
On the contrary, the performance of domestic brands represented by Changhong is indeed very gratifying and proud. Whether it is on the hot topic of artificial intelligence technology, the overall research and input of domestic consumers is higher than the richness of built-in film sources. Almost all of these international big names have taken the lead.
We have reason to believe that in the future, domestic and international markets for smart TVs will be led by domestic manufacturers such as Changhong, focusing on R&D investment and brand innovation. Here, we must make crazy calls for these “new domestic productsâ€.
