How to simulate audio input to Microphone using .wav file [closed]

Question

My target is to use a .wav file as a substitute for microphone input in the Emulator. The .wav file has to be recognized and processed by the Speech Recorder in the Android emulator.

I want to test the Speech Recorder by giving voice commands from the .wav file, as if the app had received them through the microphone input.

Is this possible?

Don't know if this is helpful or not, but on non-android systems you could use a Loopback Driver. On OSX and Linux you can use Jack Audio or Soundflower for this. Maybe searching for an android equivalent of those might lead to something? – Antinode
