ChatGPT Voice Assistant

A simple interface to the OpenAI ChatGPT model with speech to text for input and text to speech for the output. chatgpt-voice-assistant uses Google Translate's text-to-speech free API for audio input and output (not OpenAI Whisper).

Setup

Mac Prerequisites

Install dependencies:

brew install portaudio
brew link portaudio

Update your pydistutils config file for portaudio usage by running the following:

echo "[build_ext]" >> $HOME/.pydistutils.cfg
