Fast voice assistant powered by Groq, Cartesia, and Vercel.

Swift

Swift is a fast AI voice assistant.

• Groq is used for fast inference of OpenAI Whisper (for transcription) and Meta Llama 3 (for generating the text response).
• Cartesia's Sonic voice model is used for fast speech synthesis, which is streamed to the frontend.
• VAD is used to detect when the user is talking, and run callbacks on speech segments.
• The app is a Next.js project written in TypeScript and deployed to Vercel.

Thank you to the teams at Groq and Cartesia for providing access to their APIs for this demo!
