# blocksOtherRecognizers

A Boolean value that indicates whether the speech recognizer object should block all other recognizers (that is, other applications attempting to understand spoken commands) when listening.

```
var blocksOtherRecognizers: Bool { get set }
```

## Discussion

When the value of this property is <doc://com.apple.documentation/documentation/Swift/true>, all other speech recognition commands on the system are disabled until the speech recognizer is released, listening is stopped, or the property is set to <doc://com.apple.documentation/documentation/Swift/false>. Setting this property to <doc://com.apple.documentation/documentation/Swift/true> effectively takes over the computer at the expense of other applications using speech recognition, so you should use it only in circumstances that warrant it, such as when listening for a response important to overall system operation or when an application is running in full-screen mode (such as games and presentation software). The default is value of this property is <doc://com.apple.documentation/documentation/Swift/false>.
