SpaceXAI Launches Grok Voice Transcribe 2.0 with Double the Accuracy

SpaceXAI has launched Grok Voice Transcribe 2.0, a speech transcription model that doubles the accuracy of its predecessor while keeping pricing unchanged. The new model introduces improved multilingual support, speaker labeling, and other features designed to enhance transcription quality for batch and streaming use cases.

Launch and Accuracy Improvements

According to THE BRIDGE, SpaceXAI has released Grok Voice Transcribe 2.0, a new version of its speech transcription model. The company claims the model achieves twice the accuracy of its predecessor, Grok Voice Transcribe 1.0, while maintaining the same pricing.

The new model supports both batch and streaming transcription and is built on the same speech foundation model as SpaceXAI’s Grok Voice voice assistant. It also introduces improvements in multilingual accuracy, which SpaceXAI highlights as the most significant enhancement over the previous version.

Features and Pricing

Grok Voice Transcribe 2.0 includes several features designed to improve transcription quality and flexibility. It assigns start and end times, as well as confidence levels, for each transcribed word. Speaker labeling, which identifies individual speakers in a recording, is available at no additional cost. The model can also transcribe up to 8 channels individually.

Users can specify up to 100 unique terms per request to improve recognition accuracy. The model formats numbers, dates, currencies, phone numbers, and email addresses, while removing speech hesitations and detecting utterance breaks for voice agents.

Multilingual support is a key feature, with the model capable of handling dozens of languages. It automatically detects the language and tracks switches during a recording in a single process. According to THE BRIDGE, external metrics rank the model first in accuracy among 32 streaming-capable models on the Artificial Analysis leaderboard.

Pricing for the new model remains unchanged: $0.10 per hour of audio for batch processing and $0.20 per hour for streaming. Speaker labeling, timestamps, and term specification are included in this price.

Transition Plan for Users

SpaceXAI announced on September 18 that Grok Voice Transcribe 2.0 will soon become the default model for its Speech-to-Text API. The company plans to deprecate Grok Voice Transcribe 1.0 within a few weeks, though the exact timeline has not been disclosed.

Users who wish to continue using the older model during the transition period can do so by specifying the model name as "grok-voice-transcribe-1.0" in their API requests. For most users, integrating 2.0 requires no code changes to achieve improved accuracy.

What this means

LazyFounders analysis — our interpretation, not reported fact.

SpaceXAI’s launch of Grok Voice Transcribe 2.0 reflects a strategic push to improve accuracy and multilingual support without raising costs. For founders and operators relying on transcription services, this update could reduce the need for manual edits or third-party tools, particularly in multilingual use cases. The decision to deprecate the older model quickly may accelerate adoption but could also create urgency for teams needing to test and migrate.

The inclusion of features like speaker labeling and timestamping at no additional cost sets a new benchmark for competitors, potentially forcing them to reevaluate their pricing or feature sets. Startups in the AI and transcription space should monitor how this impacts customer expectations and pricing models.

Key takeaways

• Grok Voice Transcribe 2.0 offers double the accuracy of its predecessor, with a focus on multilingual support.
• Pricing remains unchanged at $0.10/hour for batch processing and $0.20/hour for streaming.
• SpaceXAI will deprecate the older model within weeks, making migration to 2.0 necessary for most users.
