Librosa uses soundfile and audioread for reading audio. This module can use PyAudio and ffmpeg underneath. It's available in the pypi repository (install with pip). You can play sound files with the pydub module. In this chapter, you'll learn how to use this helpful library to ensure all of your audio files are in the right shape for transcription.

read() extracts the raw audio data, as well as the sampling rate of the file as stored in its RIFF header, and sounddevice. Python-sounddevice In order to play WAV files, numpy and soundfile need to be installed, to open WAV files as NumPy arrays. Similar to this you can have the Jupyter notebook speak and say 'Done'.instead of finding a sound file, you can also specify a numpy array: wave = np.sin(2*np.pi*400*np.arange(10000*2)/10000) and then: Audio(wave, rate=10000, autoplay=True).You could use an external module with python. Audio playback, by default, will normalize the amplitude of the signal being played. If you're working with long signals, or do not want to load the signal into python directly, it may be better to use one of these modes. Audio can also work directly with filenames and URLs.
