STT, TTS , LLM Video Autoreply System

Job ID: 39983629

Budget: $30 – $250 USD

I need a lightweight, end-to-end solution that listens to spoken Indonesian during a live video call, converts the speech to text, passes that text through a small language model to craft an automatic reply, and then speaks the response back in a natural-sounding English voice.

Scope and key points
• Speech-to-Text: real-time transcription of incoming audio (Whisper, Google Speech, or a comparable engine).
• Language Model: compact LLM (OpenAI API, Llama.cpp, or similar) that turns the transcript into a concise reply.
• Text-to-Speech: natural voice rendering—no robotic tone—ready to play back with minimal latency.
• Pipeline: audio in ➜ STT ➜ LLM ➜ TTS ➜ audio out, all wrapped in a script or small service that I can trigger during a call.
• Compatibility: desktop environment (Windows or Linux); bonus if it can hook into common video-meeting tools via virtual audio cable or WebRTC.
• Deliverables: source code, quick-start guide, and a short demo video proving the loop works in real time.

Timing is critical—I’m aiming to see a working first cut as soon as possible, then iterate quickly if tweaks are needed. If you’ve built anything similar, I’d love to hear about it when you reply.
