Today, artificial intelligence technology has gradually become the standard for television products. However, in fact, the intelligence performance of different products varies greatly. There are some fake intelligent products that are owed by IQ. What does a smart artificial intelligence TV look like? On December 20th, Changhong Q5K artificial intelligence TV tasting was held in Beijing. Changhong Q5K and other four TV brands of the same level gathered together.
Actually, the vast majority of TVs that are simply "voice-recognized" on the market today can only be regarded as the prototype of artificial intelligence TVs. Many TVs can only perform a single semantic analysis. Changhong’s latest CHiQ Q5K series of artificial intelligence TVs with far-field voice and voiceprint recognition technology can not only answer questions, but also can understand what users need through “artificial intelligence + big data + deep learning†and achieve a breakthrough in the loss of mobile phones. The remote controller, which directly interacts with the user directly, makes the artificial intelligence television more user-friendly and has entered the AI ​​3.0 era.
The most important function of artificial intelligence is to liberate manpower, increase efficiency, and realize far-field speech recognition of “free handsâ€. TV built-in microphone array, the user can directly say a specific "wake up words" to activate the far-field voice recognition function, you can control the TV in a certain range of pure voice. 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. And within 5 meters, Q5K's speech recognition is very accurate.
Voiceprint recognition technology means that television will provide personalized visual and content services according to the 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.
Simple speech recognition is now available in many digital products. Its difficulty lies in semantic understanding. Can not understand the user's intention is a major test of artificial intelligence technology. For example, to directly tell the TV what resources they want to see, or to see the works of their favorite stars, etc. Fortunately, the performance of the five televisions is better.
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 Changhong Q5K can support voice power-off, and the other four TVs cannot use voice to boot. When saying "too bright" or "too dark", the Changhong Q5K can recognize the user's intention to "adjust brightness".
Logic ability can often tell whether the artificial intelligence television is online or not, mainly in the understanding of the relationship between people. 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.
In the process of voice interaction, it is inevitable that there will be problems with oral errors when speaking. 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." The performance of Changhong Q5K is amazing. Whether it is a typo, a homonym, or a reduced character, it can be automatically corrected to find the correct content of the user's goal. The experience of the other four televisions in this area has yet to be optimized.
The on-site comparison experience made a true reduction of the application of artificial intelligence technology in the television industry. Overall, televisions are relatively mature in speech recognition experience, and the recognition rate and accuracy rate can achieve relatively good results. Far-field speech and voiceprint identification technology, from the industry as a whole, is used less often and the technology still needs polishing. Of course, the breakthrough of artificial intelligence technology on TV still requires the joint efforts of the industry, further polishing the technology, and ultimately promoting the maturity of the entire industry.
