About Voice-based chatGPT

A free and open-source tool that enables voice-based conversations with ChatGPT. It uses the ChatGPT API to process voice input (recorded via microphone) and responds with synthesized speech, allowing for a hands-free, interactive dialogue. Built in Python, it requires Ubuntu with dependencies like espeak, ffmpeg, and portaudio19-dev. The tool normalizes ambient noise before starting and maintains a single conversation session. The repository includes future plans such as interrupting ChatGPT mid-speech, silencing PyAudio errors, and developing a web-based version.
