𝐕 The "Voice-to-Voice" Pipeline Concept The core of this technology is an efficient loop that captures human intent and returns a visual response in milliseconds. · Speech Recognition (ASR): Fast models like NVIDIA Parakeet or Whisper capture speech via mic PCM16 streams, using VAD to detect when a user starts or stops talking. · LLM & Agentic AI: Models like Gemma or GPT process conversation context and retrieve private data, allowing the AI to trigger tools (like gestures or facial expressions) mid-conversation. · Text-to-Speech (TTS): Synthesizers like Qwen3-TTS generate audio that mimics human intonation, returning it quickly alongside the textual transcript. · 3D Avatar & Lip Sync: Engines like Unreal or Three.js drive the model, using audio features (MFCC) to match visemes to sound, achieving sub-50ms latency for mouth movement. · Real-Time Rendering: The avatar is composited in real-time using streaming protocols (RTMP/W...
