# SE - Voice Isolation

> Real-time voice isolation for any acoustic environment.

The Voice Isolation SE (`VI_G_SE`) is a best-in-class model for denoising audio and clarifying speech. It extracts voices from any noisy environment in real time, removing unwanted background noise and background speech while preserving natural voice quality. With low latency and minimal computing cost, SE delivers clean speech waveforms suitable for human communication.

## Hear the Difference

Voice Isolation SE preserves only the primary speaker by removing background voices, noise, and chatter.

## Code Example

Create an audio processor with the Voice Isolation SE model:

```python theme={null}
audio_params = sanas_remote_sdk.AudioParams()
audio_params.modelName = "VI_G_SE"
audio_params.sampleRate = 16000  # Or up to 24kHz

processor, create_result = sdk.CreateAudioProcessor(audio_params)
```
