Speech recognition models

Flexible model options let you pick the best one for the job.


Unmatched performance and value

Our next-gen model surpasses all competitors in speed, accuracy, and cost. Compared to the nearest competitor, Nova is 22% more accurate, more than 20 times faster, and over 3x cheaper.


Improvements you can't miss

Our fully managed Whisper APIs are faster, more reliable, and cheaper than OpenAI's. Includes built-in diarization, word-level timestamps, and an 80x higher file size limit.


Boost performance using your data

Custom trained speech models give accuracy a noticeable boost, especially on unique customer jargon. High throughput models are also available to meet enterprise scalability requirements.

Setting new benchmarks in ASR performance

All ASR providers strive to have the most accurate transcripts possible, but what about other critical features you require? We advise performing side-by-side comparisons and testing with the real-world audio you'll use in production to determine the best speech solution for your needs.
