Product improvements

We've fixed an edge-case which would sometimes occur due to language fallback when Automatic Language Detection (ALD) was used in conjunction with language_confidence_threshold, resulting in executed transcriptions that violated the user-set language_confidence_threshold. Now such transcriptions will not execute, and instead return an error to the user.

We've made improvements to our Automatic Language Detection (ALD) model, yielding increased accuracy, expanded language support, and customizable confidence thresholds.

In particular, we have added support for 10 new languages, including Chinese, Finnish, and Hindi, to support a total of 17 languages in our Best tier. Additionally, we've achieved best in-class accuracy in 15 of those 17 languages when benchmarked against four leading providers.

Finally, we've added a customizable confidence threshold for ALD, allowing you to set a minimum confidence threshold for the detected language and be alerted if this threshold is not satisfied.

We've made improvements to our Speaker Diarization model, especially robustness in distinguishing between speakers with similar voices.

We've fixed an error in which the last word in a transcript was always attributed to the same speaker as the second-to-last word.

We've made improvements to error handling for file uploads that fail. Now if there is an error, such as a file containing no audio, the following 422 error will be returned:

Upload failed, please try again. If you continue to have issues please reach out to support@assemblyai.com

We've made scaling improvements that reduce p90 latency for some non-English languages when using the Best tier

We've made improvements to notifications for auto-refill failures. Now, users will be alerted more rapidly when their automatic payments are unsuccessful.
