Introduction

Sanas 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.
