Smart phone can't send voice message, indicating that it can't be connected. What's going on here?

Phonetic text can be used to send short messages, which requires a lot of calculation, can not be done locally, and needs to occupy network traffic. The principle is to upload the voice audio you say to the voice cloud for processing, and then download the translated text to the mobile phone. So ~ check whether your mobile phone is connected to the internet and try again!
