### VIVA SDK — Voice Intelligence for Voice AI Agents
Server-side models that sit in front of your VAD or STT pipeline, optimized for on-server CPU deployment.
| Model | Description |
|---|---|
| **Voice Isolation** | Removes background noise, secondary voices, and cross-talk from agent audio streams. Language and accent independent. |
| **Turn Prediction** | Predicts when a speaker is likely to finish their turn, enabling natural conversation flow without awkward pauses or premature interruptions. Audio-only, no transcription required. |
| **Voice Activity Detection** | Accurate real-time speech and silence detection for clean voice pipelines. Reduces false triggers and improves system responsiveness. |
### RTC SDK — Speech Enhancement for Human-to-Human Calls
Client-side and server-side models for noise cancellation, accent conversion, and voice translation.
| Model | Description |
|---|---|
| **Noise Cancellation** | Inbound and outbound noise removal, background voice cancellation, and de-reverberation. |
| **Accent Conversion** | Real-time accent transformation for contact center agents — improves CSAT and AHT. |
| **Voice Translation** | Bidirectional real-time voice-to-voice translation across multiple languages. |
