See the examples/ directory in the repository root for usage examples:
Recognize speech input from the microphone
Transcribe an audio file
Save audio data to an audio file
Show extended recognition results
Calibrate the recognizer energy threshold for ambient noise levels (see recognizer_instance.energy_threshold for details)
Listening to a microphone in the background
Various other useful recognizer features
