Ursa
Ursa è la famiglia di modelli di conversione della voce in testo di Speechmatics per trascrivere audio in diretta e registrato in diverse lingue, con accenti e parlanti diversi.
In inglese
Ursa converts speech into text for applications such as captions, search, analytics, voice agents, legal transcription, and healthcare documentation. It supports batch and real-time transcription, speaker information, timestamps, formatting, and translation workflows.
Speechmatics released Ursa 2 as its next-generation model in October 2024. Current Speechmatics pricing is usage-based and is listed by API model and processing mode rather than by the Ursa name; translation, summaries, chapters, sentiment, and topics cost extra.
