Powering incredible companies


New PII and Entity Detection Model

We’ve upgraded to a new and more accurate PII Redaction model, which improves credit card detections in particular.

We’ve made stability improvements regarding the handling and caching of web requests. These improvements additionally fix a rare issue with punctuation detection.


Multilingual and stereo audio fixes, & Japanese model retraining

We’ve fixed two edge cases in our async transcription pipeline that were producing non-deterministic results from multilingual and stereo audio.

We’ve improved word boundary detection in our Japanese automatic speech recognition model. These changes are effective immediately for all Japanese audio files submitted to AssemblyAI.
