Ursa: Scaling up as a Solution to Domain Generalization

Ursa is a new generation model for Speechmatics' Automatic Speech Recognition (ASR) system that achieves market-leading accuracy in speech transcription and demonstrates impressive performance in specialized domains through domain generalization. The model's success is driven by significant scaling up of self-supervised learning models and neural language models, which enables better understanding of every voice and expanded coverage of domain-specific vocabulary.
