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!
