<a name="voice-for-audio-prompts"></a>

You select the text-to-speech voice and language in the [Set voice](set-voice.md) block. 

You can also use SSML in Amazon Lex bots to modify the voice used by a chat bot when interacting with your customers. For more information about using SSML in Amazon Lex bots, see [Managing Messages](https://docs.aws.amazon.com/lex/latest/dg/howitworks-manage-prompts.html#msg-prompts-response) and [Managing Conversation Context](https://docs.aws.amazon.com/lex/latest/dg/context-mgmt.html#special-response) in the Amazon Lex Developer Guide.

**Tip**  
If you enter text that isn't supported for the Amazon Polly voice you are using, it won't be played. However, any other supported text in the prompt will be played. For a list of supported languages, see [Languages Supported by Amazon Polly](https://docs.aws.amazon.com/polly/latest/dg/SupportedLanguage.html).
