Recently, we have often heard the term "artificial intelligence", or AI for short. Artificial intelligence is a branch of computer science that seeks to understand the nature of intelligence and produce a new type of intelligent machine that can react in a similar way to human intelligence. Research in this area includes robotics, speech recognition, image recognition, natural language processing, and expert systems.
Now,Many TV manufacturers have also begun to make every effort to promote"Artificial intelligence TV",But from the current artificial intelligence TV on the market,The main function is still in the intelligent voice part,And intelligent voice mainly involves speech recognition、Semantic understanding、Scene coverage and other different aspects。
So is AI voice "really smart" or "pseudo-intelligent"? To this end,Wanwei Home Grid selected Haier、Weijing、PPTV、Changhong、LETV、Thunderbird, etc.6The most representative smart TV of TV brands,From the dialect type、Accuracy、Recognition speed、Recognition method、Speech recognition test in terms of adaptability。

1. Can AI voice TV recognize dialects?
Although Mandarin is very popular, there are still many areas where people do not speak Mandarin and only speak dialects, which is a big challenge for AI voice TV. So, can AI voice TV recognize dialects? How many dialects can be recognized?
To this end, WWG testers conducted a dialect test on each product, in addition to seeing if the language settings had a dialect function, but also tested the dialect type.
Test Results:
Test Reviews:
We can see that, in addition to microcrystalline TV, Haier, PPTV, Changhong, LETV, and Thunderbird cannot recognize dialects. It can be seen that,In terms of voice recognition,Most smart voice TVs have not yet perfected the dialect recognition function,The dialect recognition function needs to be further developed。
2. How high is the accuracy of artificial intelligence voice TV recognition?
Nowadays, AI TVs all wear a "smart" hat, but when you use the intelligent voice function, can it understand what you say?
The testers of the World Wide Home Grid used the same operation instructions to test the recognition accuracy of the TV, and divided it into three difficulty levels:
Difficulty 1: Hello;
Difficulty 2: I want to watch "The Legend of Chu Qiao";
Difficulty 3: I want to listen to Lin Junjie's "Jiangnan";
Test Method:
For difficulty 1 instructions, the tester asks the same question 10 times; For the Difficulty 2 and 3 instructions, the tester initiates the same question 5 times.
Test Results:
1、Haier TV responds very smoothly to the command of difficulty1,For the command of difficulty2 and difficulty3,Haier TV shows《Chu Qiaobiography》and cover song"Jiangnan"The search interface,But it can't be played directly。
2、Weijing TV has three different responses to the command of difficulty1,And the commands of difficulty2 and difficulty3are the same as Haier TV,Can't be played directly;
3. PPTV TV displays the screen of searching movies and TV for the command of difficulty 1; Difficulty 2 commands are not properly recognized and searched; Difficulty 3 commands are directly searched for movies and TV, and the commands cannot be correctly recognized;
4、Changhong TV has 1 to 5 ways to answer the instructions of difficulty 1,And the answers are humorous; For the instructions of difficulty 2 and difficulty 3, you can directly find and play;
5、LETVThe command response to level 1 difficulty is concise; Level 2 difficulty command test, which can be recognized and searched, but cannot be played; Level 3 difficulty commands, which can be searched and played, but the songs played are cover songs;
6、For level 1 instructions,Thunderbird TV has 1 to 4 simple normal responses; For Level 2 and Level 3 commands, they can be directly recognized and played.
Test Reviews:
Through the test of the accuracy of intelligent voice recognition, we have a simple impression of smart voice TV. Haier、Viking、Changhong、LETV、Thunderbird's voice recognition ability is very strong,You can search directly,But the search results of LETV's third-level command are cover songs,It should be a copyright issue。 PPTV's voice recognition function needs to be improved. In general, AI voice TV can be said to have developed very well, but it has not yet reached the level of true intelligence.
3. Is AI TV speech recognition fast?
We all know that,AIThe biggest advantage of voice TV is that there are no buttons,Save us the time of pressing the keys to search for programs,So its response speed is very important。 If the voice recognition speed of a smart voice TV takes longer than the time it takes us to search for a program by pressing a button, then it doesn't make sense. That's why we've tested the speed of speech recognition.
Test Method:
The testers tested the speech recognition speed of these smart voice TVs by recording the time when the smart voice TVs executed the "I want to listen to JJ Lin's "Jiangnan" command.
Test Results:
Test Reviews:
We can see that Haier, WeTV, PPTV, and LeTV all display search results within 1-3 seconds, while Changhong and Thunderbird take 4 seconds to display search results. This shows that smart voice TV is still doing well in voice recognition speed. The recognition speed of a few seconds allows us to find the program we want to watch, which is really convenient and time-saving.
4. What are the speech recognition methods of artificial intelligence TV?
We've all had the experience of wanting to change shows, but the remote control is far away and we don't want to get up to get it. Therefore,We still have high expectations for artificial intelligence TV,Can we switch programs directly through mobile phones or TV speakers?
In response to this pain point of users, our evaluators have also conducted relevant speech recognition tests, let's take a look at the test results.
Test Method:
Our testers searched the voice control settings on these TVs to see if they supported control methods other than the remote.
Test Results:
Test Reviews:
Through the test results, we know that,Although these six smart voice TVs cannot achieve the purpose of controlling the TV through the speaker,But it can be controlled by remote control、Mobile phone APPThe TV can be controlled by voice。 So don't worry too much if you can't find the remote control, we can control it from our mobile phone.
5. How adaptable is AI TV voice recognition?
Everyone speaks differently, maybe what you say is different, but there is only one purpose, so whether artificial intelligence TV voice recognition can deal with different problems is a key factor in testing whether it is "true intelligence" or "pseudo-intelligence".
In order to verify the adaptability of smart voice TV,Our testers set up the following test instructions,Let's take a look at the test results。
Test Instructions:
1. Find some Andy Lau movies;
2. What are Andy Lau's movies?
3. Andy Lau's films shot in recent years;
Test Method:
Perform the above test instructions separately for each TV model;
Test Results:
1、Haier TV command 1 and command 2 search results are the same,Can't play; Command 3 also can't be searched;
2. The search results of command 1 and command 2 are the same for microcrystalline TV, and they cannot be played; Command 3 cannot be searched;
3、PPTV is the same as Weiying TV,The search results of command 1 and command 2 are the same,It cannot be played; Command 3 cannot be searched;
4、The search results of command one and order two are the same for Changhong TV,Can't be played; The answer to order three is "order Andy Lau's movies in recent years", and the resources searched are different from the previous two and cannot be played;
5、Order1 and Order2The search results are the same on LETV,Can't be played; Command 3 is unrecognizable and cannot be searched;
6. Thunderbird can search for command 1 and command 2, and play the first search result, but command 3 cannot be recognized, showing "Play Andy's movies in recent years", but it can't find any movies.
Test Reviews:
After testing,Haier、Weijing、PPTV、Changhong、LETV、Thunderbird, etc. cannot fully recognize commands,It can be seen that the adaptability of smart TV voice recognition is still limited,It cannot recognize all commands,Therefore, when the next command cannot be executed,You can try to change to other commands。
Through the above evaluation content, we can know,Smart voice TV has done a good job in voice recognition,Although it is not good enough in dialect recognition,But voice search、Basic operations such as program switching are still OK,Voice recognition is very good in accuracy and recognition speed,At the same time, voice recognition also supports mobile phone APPThe control。 So how does it perform in terms of semantic understanding and scene coverage? If you are interested, you can continue to pay attention to Wanwei Home Grid, and then our testers will conduct a detailed evaluation of semantic understanding and scene coverage.
