Grok TTS

What we know about Grok TTS

Grok TTS is a text-to-speech apis platform: usage-priced hosted TTS from xAI, part of the Grok Voice stack (TTS, STT, and a speech-to-speech Voice Agent API), aimed at developers who want low-latency voice output alongside Grok models. This profile tracks what we have verified about Grok TTS, each fact linked to a primary source and dated.

Grok TTS does not publish a public per-minute rate we have been able to verify, so the price figure here stays blank until we can confirm one. We would rather show nothing than a guessed number; if you have a current Grok TTS quote, it is the fastest way for us to close that gap.

On capabilities, Grok TTS covers streaming audio output, realtime websocket api, instant voice cloning, and emotion / style controls, and does not offer self-host / on-prem option. Each of those is verified against Grok TTS's own docs or dashboard, not marketing copy.

In total we track 12 verified facts for Grok TTS today, and add coverage as the ingestion pass revisits it. Where a number is a vendor claim rather than our own measurement, it is labeled as such on the Grok TTS fact sheet below, and each row links the primary source it came from so you can check our work.

Whether Grok TTS is the right call depends on your use case more than any single spec, which is why the head-to-head verdicts below score it per scenario rather than crowning one overall winner. Use the fact sheet for the raw numbers, and the matchups for how Grok TTS actually fares against the platforms buyers most often weigh it against.
