Building an AI Voice Assistant in 1 Minute (Mac Terminal)

The author created an AI Voice Assistant in MacOS Terminal using OpenAI models. The assistant converts voice to text, processes it with an LLM, and streams the response back as audio. Three OpenAI models are utilized: Whisper for speech-to-text, GPT for text processing, and TTS for text-to-speech. An OpenAI API key is required and must be exported before running the commands. The process involves recording audio using SoX, transcribing it with Whisper, processing the text with GPT-3.5, and streaming the reply as audio using TTS and SoX. These steps can be automated using a shell script called assist.sh, making the assistant accessible via the command line. The script records a three-second audio clip, transcribes it, gets a response from GPT, and streams the reply as speech. The author suggests further extensions like using silence detection or hot-key activation. They've also implemented the assistant within an Express server for enhanced control and streaming capabilities.
