# setObject(_:forProperty:)

Specifies the value of a receiver’s property.

## Declaration

```swift
func setObject(_ object: Any?, forProperty property: NSSpeechSynthesizer.SpeechPropertyKey) throws
```

## Parameters

- `object`: The property’s new value. The supported properties are listed in NSSpeechStatusProperty Dictionary Keys.
- `property`: The property to set.

## Discussion

Discussion note: In Swift, this method returns Void and is marked with the throws keyword to indicate that it throws an error in cases of failure. You call this method in a try expression and handle any errors in the catch clauses of a do statement, as described in Error Handling in The Swift Programming Language and About Imported Cocoa Error Parameters.
