Speaker library for Picovoice.

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}
