I'm doing an app which converts from speech to text. I have googled and find that google speech api is a google choice. Now I meet a question: When user speak to ios device, how can I capture the audio file? does any Frameworks or APIs should be introduced? And what's the type of raw audio file, WAV or MP3? Thank you.
