* ABOUT GROK TTS

Working with Grok TTS

Grok TTS turns text into natural speech with five named voices — eve, ara, rex, sal and leo — and detects the language automatically across more than twenty. Inline speech tags control pauses, laughter and whispering, so delivery is directed inside the script.

When to choose Grok TTS

Choose Grok TTS when the read needs personality and you want to mark laughter or a whisper directly in the text. Google's TTS is the alternative with pacing and emphasis tags; MiniMax Speech splits on latency.

About Grok TTS

How many voices does Grok TTS offer?: Five: eve, ara, rex, sal and leo, each usable across the languages the model auto-detects.
What can inline speech tags do?: They mark pauses, laughter and whispering inside the script, so the performance is directed rather than left to chance.
Do I need to specify the language?: No. It auto-detects across more than twenty languages, so mixed-language scripts do not need per-segment configuration.
