# init(voice:)

Initializes the receiver with a voice.

```
init?(voice: NSSpeechSynthesizer.VoiceName?)
```

## Parameters

`voice`

Identifier of the voice to set as the current voice. When `nil`, the default voice is used. Passing in a specific voice means the initial speaking rate is determined by the synthesizer’s default speaking rate; passing `nil` means the speaking rate is automatically set to the rate the user specifies in Speech preferences.

## Return Value

Initialized speech synthesizer or `nil` when the voice identified by `voiceIdentifier` is not available or when there’s an allocation error.

## See Also

[`availableVoices`](/documentation/AppKit/NSSpeechSynthesizer/availableVoices)
