### Introduction

Sanas [**Speech Enhancement**](https://help.sanas.ai/portalv3/docs/speech-enhancement)( **SE**) features built-in enhancement modes that enable you to optimize audio performance in various use-case scenarios. This article describes each mode and explains how to configure them.

##### Enhancement Modes

- **Standard** - A multi-speaker mode that preserves background human speech while canceling environmental noises. Recommended for shared workstations and open-desk setups.

- **Voice Isolation** - A single-speaker mode that preserves only the primary speaker's voice while canceling distant human speech and environmental noise. Recommended for agents using a headset or personal microphone.

Voice Isolation includes the following sub-modes:

|     |     |     |
| --- | --- | --- |
| **Sub-mode** | **Description** | **Best for** |
| _Auto_ | Automatically detects the headset type. | When app users are using various headset types |
| _Headset mic_ | Detects primary speech in the near field. | Agents using headsets with a boom microphone. |
| _Built-in mic_ | Detects primary speech in the far field. | Agents using a laptop's built-in microphone or headsets without a boom microphone. |

> _Note: Standard is the default enhancement mode for SE._
