xAI 发布 Grok Voice Transcribe 2.0 语音转写模型
xAI 发布 Grok Voice Transcribe 2.0 语音转写模型,称其准确率是 Grok Voice Transcribe 1.0 的两倍,价格不变。该模型在 Artificial Analysis 公开榜单的 32 个流式模型中准确率排名第一,并支持批量与流式转写、词级时间戳、说话人分离、多声道转写和关键术语偏置等功能。批量转写定价为每小时音频 $0.10,流式为 $0.20,该模型将很快成为 Speech-to-Text API 的默认选项,1.0 版本将在未来几周内弃用。

Grok Voice already powers tens of thousands of customer-support calls a day, transcribes millions of hours of video narration, and runs voice agents in physical products, including the Grok assistant in Tesla vehicles. It is trained on a unique dataset of live, noisy, multilingual audio recorded across a diverse set of environments and refined with post-training. The result is one of the most accurate transcription models for speech in real-world settings. A
