v8.5 Asynchronous Transcription Model Released

  • Our Asynchronous Speech Recognition model is now even better with the release of v8.5.
  • This update improves overall accuracy by 4% relative to our v8 model.
  • This is achieved by improving the model’s ability to handle noisy or difficult-to-decipher audio.
  • The v8.5 model also improves Inverse Text Normalization for numbers.

New and Improved API Documentation

  • Launched the new AssemblyAI Docs, with more complete documentation and an easy-to-navigate interface so developers can effectively use and integrate with our API. Click here to view the new and improved documentation.

  • Added two new fields to the FinalTranscript response for Real-time Transcriptions. The punctuated key is a Boolean value indicating if punctuation was successful. The text_formatted key is a Boolean value indicating if Inverse Text Normalization (ITN) was successful.

Inverse Text Normalization Added to Real-Time, Word Boost Accuracy Improved

  • Inverse Text Normalization (ITN) added for our /v2/realtime and /v2/stream endpoints. ITN improves formatting of entities like numbers, dates, and proper nouns in the transcription text.

  • Improved accuracy for Custom Vocabulary (aka, Word Boosts) with the Real-Time transcription API.

  • Fixed an edge case that would sometimes cause transcription errors when disfluencies was set to true and no words were identified in the audio file.
