PvSpeaker Demo for Python
This project contains a Python command-line demo for PvSpeaker that demonstrates how to use PvSpeaker to play audio from a WAV file.
PvSpeaker
PvSpeaker is an easy-to-use, cross-platform audio player designed for real-time speech audio processing. It allows developers to send raw PCM frames to an audio device's output stream.
Compatibility
Python 3.8+
Runs on Linux (x86_64), macOS (x86_64 and arm64), Windows (x86_64), and Raspberry Pi (3, 4, 5).
Installation
pip3 install pvspeakerdemo
Usage
In the following instructions, we will refer to {AUDIO_DEVICE_INDEX} as the index of the audio device to use, and {INPUT_WAV_PATH} as the path to the pcm wav file that will be played.
{AUDIO_DEVICE_INDEX} defaults to -1 and {INPUT_WAV_PATH} must not be empty.
To show the available audio devices run:
pv_speaker_demo --show_audio_devices
To run PvSpeaker run:
pv_speaker_demo --audio_device_index {AUDIO_DEVICE_INDEX} --input_wav_path {INPUT_WAV_PATH}
Hit Ctrl+C if you wish to stop playing audio before it completes. If no audio device index (-d) is provided, the demo will use the system's default audio player device.
