# Can you make voices produce the sound of breathing?

Yes. With Eleven v4 and Eleven v3, you can use audio tags such as `[sighs]` or `[exhales]` to add breathing and similar reactions to generated speech.

See the [prompting guide](/docs/overview/capabilities/text-to-speech/best-practices#prompting-eleven-v4) for more detail on audio tags and delivery control.
