# supportsOnDeviceRecognition

A Boolean value that indicates whether the speech recognizer can operate without network access.

## Declaration

```swift
var supportsOnDeviceRecognition: Bool { get set }
```

## Discussion

Discussion An SFSpeechRecognitionRequest can only honor its requiresOnDeviceRecognition property if supportsOnDeviceRecognition is true. If supportsOnDeviceRecognition is false, the SFSpeechRecognizer requires a network in order to recognize speech.
