# language

A BCP 47 code that contains the voice’s language and locale.

## Declaration

```swift
var language: String { get }
```

## Discussion

Discussion The language of a voice controls the conversion of text to spoken phonemes. For best results, ensure that the language of an utterance’s text matches the voice for the utterance. The locale of a voice reflects regional variations in pronunciation or accent. For example, a voice with a language code of en-US speaks English text with a North American accent, and a language code of en-AU speaks English text with an Australian accent.
