## Grok Voice Transcribe 2.0 launches
SpaceXAI released Grok Voice Transcribe 2.0, a speech-to-text model that's twice as accurate as version 1.0 while costing the same. It ranks first for accuracy among 32 streaming models on the Artificial Analysis leaderboard.

## Built for real-world audio
Grok Voice Transcribe 2.0 handles the messiest audio: phone lines, overlapping voices, accents, and spoken credentials. It's trained on live, noisy, multilingual recordings from diverse environments.
## Multilingual breakthrough
Grok Voice Transcribe 2.0 transcribes dozens of languages, auto-detects the language, and handles mid-recording switches in one pass. On short phrases, word error rate dropped from 20.6% to 6.8%.
## Existing integrations get better
Current Speech-to-Text API users get the accuracy boost with no code changes. The model supports batch and streaming, word-level timestamps, speaker diarization, multichannel transcription, and key term biasing.
## Atlassian Loom partnership
Atlassian Loom now uses Grok Voice Transcribe 2.0 for video transcription. The accurate transcripts enable new workflows: record an action plan in Loom, pipe it to Cursor, and it generates code updates automatically.

## Same price, better accuracy
Batch transcription costs $0.10 per hour of audio, streaming $0.20 per hour. Diarization, timestamps, and key term biasing are included at no extra cost.
## Version 1.0 being deprecated
Grok Voice Transcribe 2.0 will become the default in the Speech-to-Text API. Version 1.0 will be deprecated in the coming weeks, but users can pin it to stay on the older model during transition.
## Key takeaway

Grok Voice Transcribe 2.0 achieves industry-leading accuracy on real-world audio while maintaining the same pricing as the previous version.
