# SpeechDetector.SensitivityLevel

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

```
enum SensitivityLevel
```

## Overview

[`SpeechDetector.SensitivityLevel.low`](/documentation/Speech/SpeechDetector/SensitivityLevel/low) will allow for a more “forgiving” VAD model, whereas selecting [`SpeechDetector.SensitivityLevel.high`](/documentation/Speech/SpeechDetector/SensitivityLevel/high) will make the model more aggressive. [`SpeechDetector.SensitivityLevel.medium`](/documentation/Speech/SpeechDetector/SensitivityLevel/medium) is the recommended level for most use cases.
