Grok now offers standalone Speech-to-Text and Text-to-Speech APIs for developers. The new voice stack covers real-time and batch transcription, multispeaker diarization, multichannel audio, text formatting, expressive TTS with speech tags, multilingual support, and simple usage-based pricing.
With the new transcription (Speech-to-Text) API now available, combined with their Voice Agent capabilities, it’s clear that @Grok is making a systematic push to capture the entire Voice AI ecosystem.
Looking specifically at the STT model, they have shipped a highly pragmatic feature set. It includes native WebSocket support for real-time streaming, built-in speaker diarization (a must-have for meetings), and intelligent text formatting that automatically handles numbers and currencies (it's cool and pretty useful in production!).
The pricing is also very aggressive: $0.10 per hour for batch and $0.20 per hour for streaming. xAI is once again putting some real price pressure on the market, isn't it?
