Our frame-based pipeline architecture delivers industry-leading response times:

```
User Speech → VAD Detection → STT (streaming) → LLM → TTS (streaming) → Audio Output
     ↓             ↓              ↓            ↓          ↓              ↓
   ~50ms        ~100ms         ~150ms       ~200ms     ~100ms         ~50ms
                                                    Total: ~500ms
```

### Native Audio Support

With Gemini Live 2.0/2.5, bypass STT and TTS entirely for even lower latency:

```
User Speech → Gemini Live (Audio-to-Audio) → Audio Output

```
