Language Model/transcripts
Some of the recent /transcripts endpoint language model updates (de, en, en-GB, fr) have been rolled back so that performance of asynchronous audio file processing can be improved. An update is expected November 2025 to improve performance.Until such time, speech recognition accuracy from /transcripts asynchronous audio file processing may be degraded as compared to real-time audio processing via the /stream and /transcribe APIs, which are not impacted by this issue.

API/transcripts
Definition of the parameter modelName is no longer required in /transcripts API requests. The latest and greatest model available per language will be applied automatically.If the argument is included in the request, then it will be ignored. If the configuration is otherwise valid, then the request will process as expected. See full specification here.

API/transcribe
The preview (interim) results feature of the transcribe API is not performing as expected. As a result, it is being disabled for most languages to prevent issues with speech lag, speech recognition accuracy, or web socket connectivity. Please reach out to us directly if you have questions or concerns about this dictation feature.
