Why can't voice input be converted into text?

According to the encyclopedia, the reasons why you can't input text by voice are as follows:

1, with limited functions. When chatting on WeChat, you can send all kinds of files, and "voice to text" needs to call the microphone, receiver, speaker, browsing storage memory and other permissions of the mobile phone system. If the user closes the corresponding permissions, it will lead to "speech to text failure". After opening the corresponding permissions, it can be converted normally.

2. Network failure. Under normal circumstances, users will directly receive the voice sent by their friends, but they need to recognize the audio again and use the network when converting. If the network fluctuates or fails, it will lead to "speech-to-text failure" and the conversion will succeed again.

3. Mandarin is not standard. Although WeChat can recognize most international languages, it can't recognize Chinese dialects. When some users use WeChat to send voice, they will have some hometown accent and some local dialect, which cannot be recognized by artificial intelligence, nor can they be directly translated into Mandarin or text, so there will be a prompt of "voice-to-text failure" unless the other party speaks Mandarin, otherwise it cannot be solved.

4. There is no audio. This situation is quite special. Under normal circumstances, when friends send audio to themselves, there must be sound. However, if the microphone of the other party's mobile phone is damaged, or WeChat's permission to use the microphone of the mobile phone is turned off, although voice can be sent, the voice only contains the duration, and there is no sound, so the artificial AI cannot recognize the voice, so it cannot be converted into text, and the prompt "Voice to text failed" appears. If you can't hear, you can listen to the sound.

5. Illegal documents. When some users send voice, they use the plug-in version of WeChat. This kind of WeChat can compress audio files, and the 30-second voice file may only be displayed for 3-5 seconds after being compressed and sent. When the system recognizes this compressed audio file, there may be a prompt that "speech to audio failed", which is normal, just let the other party resend it directly.

6. System problems. It may be that the system is under maintenance or the system is stuck. In this case, just wait until the maintenance is over.
