问题
I'm programming an App for iOS which should recognise the human user speech with MonoTouch. I need to use the microphone and convert the Voice-File into FLAC format, in order to send it to the Google Speech API.
Are there any Libraries/Code examples, or is it possible to build a Speech-Recognition App for iOS using MonoTouch and for example the Google Speech API?
Or is it possible to convert the audio Output(a .caf file) to a .flac file?
