Updated Danish (
da) language model is now available for dictation (/transcribe) and ambient (/stream) use cases. The language is rated as Premier since over 158,000 medical terms were included in the training and validation data sets.Updated French (
fr) language model is now available for dictation (/transcribe) and ambient (/stream) use cases. The language is rated as Premier since over 170,000 medical terms were included in the training and validation data sets.Norwegian (
no) and Dutch (nl) are now available for use on the /transcribe endpoint for dictation use cases. As a result they have been moved to the Enhanced language tier. Additionally, Hungarian (hu) medical terminology has been expanded and improved.See more information about supported functionality for dictation here and language tiers here.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.Updated English (
en) Premier language model is now available for dictation (/transcribe), ambient (/stream), and transcription (/transcripts) use cases. Over 170,000 medical terms were included in the training and validation data sets.Update to both streaming and asynchronous audio file processing so that transcoding is supported. Previously audio files were required to conform to 16-bit, 16kHz formatting. Now, assuming proper file types are used, any precision and sample rate are accepted. See more details here.
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.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.
