# SpeechDetector.SensitivityLevel

Determines how “aggressive” the voice activity detection (VAD) model will be.

## Declaration

```swift
enum SensitivityLevel
```

## Overview

Overview SpeechDetector.SensitivityLevel.low will allow for a more “forgiving” VAD model, whereas selecting SpeechDetector.SensitivityLevel.high will make the model more aggressive. SpeechDetector.SensitivityLevel.medium is the recommended level for most use cases.
