To build an AI Voice Assistant in MacOS Terminal, the process involves using OpenAI models like Whisper for speech-to-text conversion, GPT for text processing, and TTS for text-to-speech conversion.
The setup includes exporting the OpenAI API key and running commands to record audio, convert it to text using Whisper model, process the text with GPT-3.5, and stream back the reply as speech.
By creating a script named assist.sh, users can easily record audio, transcribe it, chat with GPT, and convert the output to speech using the TTS API. The script automates the entire process.
The AI assistant built within MacOS Terminal can be extended for various functionalities like listening until silence, using hot-keys for activation, or integrating with an express server for better control and streaming on embedded devices.
