Nowadays, many television manufacturers have also begun to push forward "artificial intelligence television". However, from the perspective of artificial intelligence televisions currently on the market, the main function is still in the part of intelligent speech, and intelligent speech mainly involves speech recognition, semantic understanding, and scenes. Coverage and other aspects.
So is artificial intelligence voice really intelligent or pseudo-smart? To this end, Wanwei’s home network selected Haier, Microwhale, PPTV, Changhong, LeTV, and Thunderbird as the most representative types of smart TVs from different types of dialects, accuracy, speed of recognition, recognition methods, and resilience. Perform speech recognition tests.
Test Products: Haier LQ65AL88M92, Microwhale 49D2U3000, PPTV N55, Changhong 55Q5N, Music Super 4X55M, Thunderbird I55C-UI
First, can artificial intelligence voice TV be able to recognize dialects?
Although Mandarin is very popular at present, people in many regions do not speak Mandarin and speak only dialects, which is a big challenge for artificial intelligence voice TV. So, can artificial intelligence voice TV be able to recognize dialects? There are several types of identification dialects?
For this purpose, testers of Wanwei home network conducted a dialect test on each product. By checking whether there is a dialect function on the language setting, the type of its dialect was also tested.
Test Results:
Test Comments:
We can see that except for the small whale TV, which has a dialect recognition function, Haier, PPTV, Changhong, LeTV, and Thunderbird cannot recognize dialects. It can be seen that in speech recognition, most intelligent speech TVs have not perfected the dialect recognition function, and the dialect recognition function still needs to be developed.
Second, the accuracy of artificial intelligence voice TV recognition how high?
AI TVs are now wearing a hat called "smart", but when you use smart voice, can it understand what you say?
The testers of the Wanwei home network used the same instructions to test the accuracy of the TV's recognition and divided it into three difficulty levels:
Difficulty 1: Hello
Difficulty 2: I want to see Chu Chuo Biography;
Difficulty 3: I want to hear Lin Junjie's "Jiangnan";
Test Methods:
For the difficulty one instruction, the testers initiated the same questioning 10 times; difficulty two and difficulty three instructions, and the testers initiated the same questioning five times.
Test Results:
1. Haier TV responded easily to the difficulty one instruction; for the difficulty two and difficulty three instructions, Haier TV appeared in the search field of “Chu Qiao Biography†and cover song “Jiangnan†and could not be played directly;
2. Little whale TV has three different answers to the difficulty one instruction. The instructions for difficulty two and difficulty three, like Haier TV, cannot be played directly;
3, PPTV TV for the difficulty of a command, displayed as a search for film and television pictures; difficulty two commands can not correctly identify and search; for the difficulty of three instructions, direct search for film and television, can not correctly identify the instructions;
4, Changhong TV for the difficulty of a command, respectively, 1 - 5 kinds of answer, and answer humor; for difficulty two and difficulty three instructions can be directly search and play;
5, LeTV as for the difficulty of a command, made a simple response; for the difficulty of two command tests, can identify and search, can not play; for the difficulty of the three commands, can search and play, but the song is played cover songs;
6, Thunderbird TV for the difficulty of a command, there are 1 - 4 kinds of simple and normal answer; for difficulty two and difficulty three instructions can be identified and played directly.
Test Comments:
We passed a test of the accuracy of intelligent speech recognition, probably having a simple impression of intelligent speech TV. Haier, Microwhale, Changhong, LeTV, Thunderbird are still very capable of speech recognition, and can search directly. However, LeTV has searched for songs that are difficult to find but it is a copyright issue. PPTV still needs to be strengthened in voice recognition function. In general, artificial intelligence voice TV can be said to have developed very well, but it has not really reached the point of intelligence.
Third, the artificial intelligence TV's speech recognition speed?
We all know that the biggest advantage of artificial intelligence voice TV is that it is free of keystrokes, which saves us the time it takes to search for programs by key, so its response is very important. If the voice recognition speed of a smart voice TV is faster than the time it takes for us to search for programs by key More, then it doesn't make any sense. For this purpose, we have specifically done a speech recognition speed test.
Test Methods:
The testers measured the speed of their voice recognition by recording the time they spent on the "I want to hear Lin Junjie's "Jiangnan"" instruction on these intelligent voice TVs.
Test Results:
Test Comments:
We can see that Haier, Micro whale, PPTV, and LeTV all have search results within 1-3 seconds. Changhong and Thunderbird need 4 seconds to have the results of the search. This shows that intelligent voice TV is in terms of voice recognition speed. It's still very good, a few seconds of recognition speed let us find the program we want to see, it is indeed a lot of convenience and save time.
Fourth, what kind of voice recognition methods do artificial intelligence television have?
We all have this experience, want to switch programs, remote control does not want to get up in the distance to get up, so we still have great expectations for artificial intelligence TV, is it right? Can be directly through the mobile phone or TV speakers, we switch programs purpose?
In response to the user's pain point, our reviewers also conducted relevant speech recognition tests. Let's take a look at the test results.
Test Methods:
Our testers look through the settings to find out how these TVs are controlled by voice and see if they support any control other than the remote control.
Test Results:
Test Comments:
Through the test results, we learned that although these six intelligent voice TVs fail to achieve the purpose of controlling the TV by a speaker, they can use the remote control and the mobile phone APP to control the TV in a voice manner, so if the remote control is found, No need to worry about it too much, we can control it with a mobile phone.
Fifth, the adaptability of artificial intelligence TV voice recognition is not strong in the end?
Everyone's way of speaking is different. Maybe you say something different, but your purpose is only one. So the adaptability of artificial speech recognition in artificial intelligence TV can't cope with different questions. This is also a test of what it is. "True intelligence" is also a key factor in "pseudo intelligence."
In order to verify the resilience of intelligent voice TV, our testers set up the following test instructions. Let's take a look at the test results.
Test instructions:
First, look for Andy Lau's films;
2. What are the films of Andy Lau?
3. The films that Andy shot during these years;
Test Methods:
Perform the above test instructions for each TV separately;
Test Results:
1. Haier TV has the same search results for both Order One and Order Two and cannot be played. For Command Three, it cannot be searched.
2. Little whale TVs have the same search results for instruction one and instruction two and cannot be played; for instruction three, they cannot be searched;
3, PPTV and micro-whale TV, the search results for the instruction one and instruction two are the same, can not play; for the instruction three, can not search;
4. Changhong TV has the same search results for both Order One and Order Two and cannot be played. For Order Three, the answer result is "On Demandy Andy Lau's films for these years", and the resources searched out are different from the previous two and cannot be played.
5, LeTV as the search results for the command one and the second command is the same, can not play; for the command three, can not identify, can not search;
6. The Thunderbird can search for the first order and the second order, and play the first search result; while the order three cannot be identified, it can be displayed as "During the movie of Dehua over the years."
Test Comments:
After testing, we can know that Haier, Micro whale, PPTV, Changhong, LeTV, and Thunderbird can't completely recognize the command. It can be seen that the adaptability of voice recognition for intelligent voice TV is limited, and it is not possible to identify all instructions. Therefore, when the issuing instructions cannot be implemented, you can try to replace other instructions.
After the above evaluation content, we can learn that intelligent voice TV does a good job in speech recognition, although the recognition of dialects is not good enough, but it can do basic operations such as voice search, switching programs, voice recognition accuracy The recognition speed is very good. At the same time, the voice recognition method also supports the mobile phone APP control. How does it function in terms of semantic understanding and scene coverage? Interested friends can continue to pay attention to the World Wide Web, and our testers will then conduct a detailed evaluation of semantic understanding and scene coverage.
