Grok TTS
by xAI
xAI's text-to-speech — five expressive voices at the standard rate.
Grok TTS is xAI's speech model, available in Z1 Canvas with five built-in voices: Ara, Eve, Leo, Rex and Sal. It is priced at the same per-character rate as OpenAI Standard, so switching is a matter of taste rather than budget.
Reach for it when you want a different character of voice than the OpenAI set — it reads with a little more energy, which suits short, punchy ad copy.
