Product improvements

Our Speaker Diarization service now supports Ukrainian speech. This update enables automatic speaker labeling for Ukrainian audio files, making transcripts more readable and powering downstream features in multi-speaker contexts.

Here's how you can get started obtaining Ukrainian speaker labels using our Python SDK:

import assemblyai as aai

aai.settings.api_key = "<YOUR_API_KEY>"
audio_file = "/path/to/your/file"

config = aai.TranscriptionConfig(
  speaker_labels=True,
  language_code="uk"
)

transcript = aai.Transcriber().transcribe(audio_file, config)

for utterance in transcript.utterances:
  print(f"Speaker {utterance.speaker}: {utterance.text}")

As previously announced, we sunset Claude 2 and Claude 2.1 for LeMUR on February 6th.

If you were previously using these models, we recommended switching to Claude 3.5 Sonnet, which is both more performant and less expensive than Claude 2. You can do so via the final_model parameter in LeMUR requests. Additionally, this parameter is now required.

Additionally, we have sunset the lemur/v3/generate/action-items endpoint.

We have reduced Universal-2's hallucination rate for the string "sa" during periods of silence.

We have fixed a rare bug in our Speaker Labels service that would occasionally cause requests to fail and return a server error.

We've fixed an issue which caused the audio_start_from and audio_end_at parameters to not be respected for multichannel audio.

We have reduced Universal-2's hallucination rate for the word "it" during periods of silence.
