# SpaceXAI cuts Grok voice transcription error rate to 6.8%

*2026-09-19 · Source: [MarkTechPost](https://www.marktechpost.com/2026/09/18/spacexai-releases-grok-voice-transcribe-2-0/)*

SpaceXAI released Grok Voice Transcribe 2.0, a speech-to-text API for batch and streaming audio. The company says short-phrase word error rate across 19 languages fell from 20.6% to 6.8% versus version 1.0, while pricing stays at $0.10 per hour for batch and $0.20 per hour for streaming.

**Why it matters:** Cheap, accurate transcription underpins voice agents, meeting tools, and accessibility products, and a roughly threefold error-rate cut at unchanged pricing raises the competitive bar for rival speech APIs from OpenAI and Google.
