AI Interviewer
A voice-based AI interview simulator powered by LLaMA 3.2 and Google Whisper. It enables candidates to practice real-time interviews using speech recognition and language generation.
Voice Interaction Features
- • Real-time speech-to-text via Google Whisper
- • Natural conversation flow using LLaMA 3.2
- • Headless interface (Mic/Speaker only)
- • Dynamic audio response with TTS engine
Backend Pipeline
- • Audio capture module receives mic input
- • Whisper STT transcribes speech to text
- • LLaMA 3.2 processes and generates replies
- • TTS engine converts responses to audio
- • Response audio streamed back to client speaker
Performance Highlights
- • End-to-end latency under 1.5 seconds
- • Seamless offline/on-device speech inference (optional)
- • Modular STT/LLM/TTS components for easy scaling
