This article introduces the relevant knowledge of "how to achieve android voice input". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Voice input is integrated with iFLYTEK's SDK, which simply realizes the process of converting speech into text. Of course, iFLYTEK also provides a lot of interfaces to achieve a more complex speech recognition system.

Layout file:

MainActivity comments are very detailed, do not repeat, do not understand can leave a message to learn together.
