Grok TTS API debuts, five voices

This looks less like a cute TTS add-on and more like xAI staking out the full voice stack around Grok.

• –xAI now exposes voice agents, text to speech, and speech to text under one umbrella, which reduces the need to stitch together multiple vendors.
• –The API returns raw audio and supports inline expressive tags, so it is built for product UX, not just demo playback.
• –Five voices and a beta label suggest the surface area is still narrow, but the 20-language support makes it immediately usable.
• –Pricing at $4.20 per 1M characters is a clear production signal, even if the product is still early.
• –Product Hunt’s Grok launch trail suggests xAI is methodically turning Grok into an API family, not a single chatbot feature.
