AssemblyAI vs Deepgram: Accuracy & Speed Compared
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
