# init(voice:)

Initializes the receiver with a voice.

## Declaration

```swift
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

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