Grok TTS is xAI's text-to-speech model. You paste a script of up to 15,000 characters, choose a voice and a language (or leave the language on auto-detect), and it reads the script aloud. Inline tags such as [pause] or [laugh] add a sound at one point, and wrapping tags such as <whisper>...</whisper> change how a passage is delivered. On Versely it costs 4 credits per 1,000 characters.

How do Grok TTS speech tags work?+
There are two kinds. An inline tag in square brackets, such as [pause] or [laugh], makes a sound at the point where you type it; xAI groups these as pauses, laughter and crying, mouth sounds and breathing. A wrapping tag, such as <whisper>it was a secret</whisper>, changes how the words between the opening and closing tag are said; its groups are volume and intensity, pitch and speed, and vocal style such as singing.
