When it comes to intelligence, many TVs are limited to the installation of applications and the interconnection with mobile phones. Although they also support voice input, the user experience is very poor. The speech recognition rate is low, and only fixed grammar can be input, so there are few applicable scenarios. The remote control must be operated at close range, etc. It can only be regarded as the embryonic form of artificial intelligence TV, which belongs to the product of AI 1.0 era. What can do "semantic analysis" is the advanced AI 2.0 era artificial intelligence TV, which realizes the function of analysis and recommendation by understanding user semantics. Changhong's latest CHiQ Q5K series artificial intelligence TV adopts far-field voice and voiceprint recognition technology, which can not only answer, but also understand what users need through "artificial intelligence+big data+deep learning", realize losing the mobile phone and remote control, and directly interact with users naturally, making artificial intelligence TV more humanized and entering the AI 3.0 era.
So is it really that smart? At present, this TV has come to our evaluation room, and the author will take you to verify it. The first thing I sent you was its main parameter configuration.

Q5K Voice Test of Changhong Artificial Intelligence TV
The biggest selling point of Changhong artificial intelligence TV Q5K is the artificial intelligence voice part. After three generations of iterative upgrading, Q5K has further improved the ability of human-computer interaction technology and machine deep learning, and created more service scenarios. At the same time, the addition of far-field voice, voiceprint recognition, ultra-fuzzy movie search and voice control operation also makes the computer interaction experience simpler and more natural.

There is no need for a traditional voice remote controller.
Accurate recognition of far-field speech beyond 5 meters
Needless to say, voice interaction brings convenience to human beings, but the traditional voice interaction needs manual operation, such as holding down the remote control to send voice instructions, which is still limited in convenience and speed. At this time, the advantage that far-field speech recognition can really "free hands" is reflected. Through the built-in microphone array of TV, the far-field speech recognition function can be activated by saying specific "wake-up words" without touching any equipment, so that TV can be controlled by pure voice in a certain range.
▲ Far-field voice boot test
The first function to be tested is far-field speech. Changhong Q5K was tested at 1 m, 2 m, 3 m, 4 m and 5 m respectively, and the sound level was the same. The test statement is: "Changhong Xiaobai, turn on the TV". It is found that Q5K's speech recognition is very accurate within 5 meters. When the author tries a longer distance, he can accurately identify it as long as the volume is slightly increased, which is difficult to achieve on other TVs.
Voiceprint recognition automatically recognizes users.
With the help of voiceprint recognition technology, TV will provide personalized visual and content services according to the recognized roles (such as men, women and children). Changhong Q5K supports multi-person voiceprint registration and role classification. It will distinguish who is currently using TV according to the different voices of each person, and learn to analyze the habits of users using TV, so as to achieve accurate content recommendation.
The actual effect is that boys and girls say "I want to watch movies" to Changhong Q5K respectively, and Q5K will present different visual effects and recommend movies according to identity recognition. The interface for women is soft pink, and the recommended films are mainly romantic films. Men will see dark blue vision and some action and science fiction films. If you are a child, you will get some recommended results of cartoons.
Basic skills test of semantic understanding
At present, mainstream smart TVs in the market basically have the function of speech recognition, and the difficulty of speech interaction lies in semantic understanding. Whether we can understand the user's intention is a big test of artificial intelligence technology. Therefore, we have specially selected several types of test items, each of which uses a variety of instructions to see if the TV can be accurately executed.
In the most basic function test, we tested some functions that users use the most every day, including finding films, checking weather, checking names and so on. Can be accurately realized. In the process of playing, Changhong Q5K TV can also complete operating instructions such as mute, setting, return, volume increase and decrease through voice control. Advanced, such as "too bright" and "too dark", Changhong Q5K can recognize the user's intention to "adjust brightness". Changhong Q5K can accurately find Deng Chao's movies and Chen Xiao's TV series by saying "I want to watch Sun Li's husband's movies" and "I want to watch Michelle Chen's husband's TV series" in the process of finding films.
Fuzzy search is not afraid of not remembering the film title.
In the interactive mode with voice as the carrier, it is inevitable that there will be a slip of the tongue. Sometimes users may mispronounce words at once, and sometimes uncommon words are easy to say wrong. In the case of user's objective instruction error or machine's own identification error, whether the TV set has the self-correcting ability to find correct audio and video content for users is a competitive point to be tested in this test.
We deliberately confused "the brother who sleeps in your upper bunk" with "the brother who sleeps in your lower bunk", but we didn't really get what we wanted. It can be said that Changhong Q5K can automatically correct any typos, homophones and missing words, and find the correct content referred to by users.
Summary:
Changhong artificial intelligence TV Q5K can be said to be the most natural, accurate and efficient artificial intelligence in the TV industry at present. Voice input is no longer a gimmick, so you can really get rid of the remote control.
How is the picture quality? The measured results give you the answer.
As a high-end 4K TV, the image quality is the core factor, and the actual performance of Changhong 55Q5K is also our concern. Tested by professional instrument BM-7 (brightness meter), the specific picture quality performance parameters of Changhong Q5K TV are: when the LED backlight is adjusted to the maximum, the measured brightness reaches 408.3 nits, and the contrast reaches 1236: 1, in which the brightness is obviously higher than the average level of 300 nits on the market at present, and the performance is excellent.
▲ Measurement results of image quality
The measured NTSC color gamut is 78.23%, which basically covers the color gamut range of 100%SRGB, slightly higher than the NTSC color gamut range of ordinary TV about 74%, and its performance is relatively good. (Note: The following color gamut range diagram shows the color ranges displayed by different standard color gamuts. )
▲ Measured color gamut range
In terms of clarity, we specially played the test film source. In the actual test, this TV has reached a high level, and there is no obvious tailing phenomenon in the dynamic picture.
▲ Dynamic definition test film source
As a 4K ultra-high definition TV, the performance of picture details is also worthy of attention. Let's release a set of real ultra-high definition pictures and videos. Screenshots will inevitably be slightly distorted, but through the comparison of different pictures, we can still see the accuracy and transitional nature of color performance. For example, the skin color of the characters in the picture below and the display of red and green are all excellent levels in the same level of TV.

During the test, we played the local files, and there was no frame skipping during the full HD or 4K ultra-clear resources. Play smoothly, fast forward and fast backward operation is also very sensitive, which fully reflects the decoding ability of the whole TV. Especially when playing movies in 4K HDR format, it can be clearly seen that both the bright part and the dark part are optimized, and the light and dark details are very obvious, which is better than most products of the same price at present.
▲4K HDR format movie playback test
Nowadays, for a TV, sound quality is as important as picture quality, and consumers are eager to get the shocking effect of the cinema version without leaving home. Changhong artificial intelligence TV Q5K adopts the front waterfall sound setting, has a large sound cavity of 1500ml, and combines the latest Dolby MS 12 surround experience technology to make stereo surround sound everywhere, which is more outstanding than traditional LCD TV speakers in effect performance.
▲ The speaker cavity is hidden at the bottom of the fuselage.
In the testing part, we selected a special audition CD and a high-definition blockbuster "Iron Man 3" to play the experience.
▲ HD DTS surround sound source
In terms of performance, the sound source is purer and the bass is more shocking, which further enhances the sense of presence when watching TV. Judging from the playback effect, the most impressive thing is undoubtedly the low frequency, which brings rich bass texture. From missile launch to explosion and the impact of Iron Man armor, we can clearly perceive it.
Summary:
Excellent picture quality and sound quality, true and natural color reproduction, smooth color transition, better dynamic picture effect and strong sound quality shock.
