AI voice products need to know who spoke and what they said. That is harder than transcription or diarization alone, especially when speakers talk over each other. Pulse by @smallest_AI is now #1 on the Diarization + ASR track of the @voicearena_ai's Diarization Bench, with 24.4% DER. DER is an error rate, so lower is better. The next system in the track scores 40.7%.
