How to check if an Android device has voice capabilities

Question

Does anyone know a good way of programmaticaly checking if an Android device, phone or tablet, has voice capabilities? By voice capabilities I mean capability to make phone call

Answer 1

I would assume that prepare() would fail if there is not mic available:

  mRecorder = new MediaRecorder();
  mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
  mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
  mRecorder.setOutputFile(audio_file);
  mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
  try {
      mRecorder.prepare();
      mRecorder.start();
  } catch (Exception e) {}
