# supportedLanguages

A list of BCP 47 codes that identify the languages a voice supports.

## Declaration

```swift
var supportedLanguages: [String] { get }
```

## Discussion

Discussion These languages are what a voice supports — when given a multi-language phrase — without the need to switch voice. For example, if the primary language is zh-CN, and this value contains zh-CN and en-US, a synthesizer that receives a phrase with both languages would speak the entire phrase.
