AssemblyAI claims Universal-3 Pro beats Deepgram Nova-3 on critical speech-to-text accuracy

By PulseAugur Editorial · [1 sources] ·

AssemblyAI has published a comparison of its Universal-3 Pro model against Deepgram's Nova-3 for speech-to-text services. The comparison emphasizes "missed-entity rate" over traditional Word Error Rate (WER), arguing that accuracy on critical terms like phone numbers or medical names is more important for production applications. AssemblyAI claims its Universal-3 Pro has a lower missed-entity rate, particularly in challenging audio conditions, and offers more robust prompting capabilities for customization. AI

IMPACT Highlights the importance of entity accuracy over raw word error rate for production speech-to-text applications.
