VoiceDesk

Lightweight Python voice assistant pipeline using Groq Whisper for ASR, Llama 3.3 70B for response generation, and gTTS for speech output — with custom conversation memory.

Source Code

The Challenge

Existing voice assistants rely on expensive cloud APIs and lack privacy. Users needed a local-first solution that works without paid subscriptions.

Engineering Solution

Built a complete voice assistant pipeline using open-source models — Groq Whisper for speech recognition, Llama 3.3 for intelligence, and gTTS for responses.
