## What happened
SpaceXAI released Grok Voice Transcribe 2.0, a speech-to-text (STT) API that claims to be twice as accurate as version 1.0 while maintaining the same pricing ($0.10 per hour for batch and $0.20 for streaming). The model supports multilingual transcription with automatic language detection and handles noisy audio environments effectively.

## Why it matters
Grok Voice Transcribe 2.0 addresses challenges in speech recognition, such as handling diverse accents, competing voices, and noisy conditions. It is particularly useful for applications like customer support calls and voice assistants. The API's improved accuracy can enhance user experience by reducing transcription errors significantly.

## For builders
Developers can integrate Grok Voice Transcribe 2.0 into their projects using the Speech to Text API. Key features include batch and streaming modes, word-level timestamps, speaker diarization, multichannel transcription, key term biasing, text formatting, filler word removal, and smart turn detection.
