Android speech recognizing and audio recording in the same time

Question

My application records audio using MediaRecorder class in AsyncTask and also use Google API transform speech to text - Recognizer Intent - using the code from this question

Answer 1

Recent projects on 'google-speech' and on 'android-opus' (opuslib) allow simple, concurrent recognition along with audio record to an opus file in android ext. storage.

Looking at the VoiceRecorder in the speech project , with only a few extra lines of code after reading the microphone buffer, the buffer can also be consumed by a fileSink (PCM16 to Opus-codec) in addition to the current speech-observer.
