VoiceArena Diarization Bench Ranks 12 Speaker-Diarization Systems
A leaderboard number for diarization is meaningless without knowing the collar tolerance, so teams comparing vendors should check scoring settings before trusting published DER figures. Developers building multi-speaker voice agents can use the bench to pick a system that holds up under overlap. VoiceArena's suites now cover diarization alongside STT, TTS and conversational agents, making it a one-stop evaluation point.
