Introduction

This video demonstrates building a voice-activated chat assistant using Node.js, OpenAI's Whisper API for speech-to-text, the Chat Completions API for generating responses, and the TTS API for text-to-speech output. The tutorial aims to guide viewers through the process in under five minutes.

Key Takeaways

• A functional voice assistant is built using Node.js and OpenAI APIs (Whisper, Chat Completions, and TTS).
• The process involves transcribing user speech, processing it through the Chat Completions API, and converting the response to speech using the TTS API.
• The code utilizes several functions, including setting up a readline interface for user input, starting and stopping audio recording, transcribing audio, processing the transcript via the Chat Completions API, and streaming the audio response.
• The code is available in the video description.
• Error handling and context management (for maintaining conversation history) are included in the code.
