Benchmarking STT for Voice Agents

calendar_today February 13, 2026 person Mark Backman domain daily-co

Today we’re releasing a new benchmark for Speech-to-Text (STT) providers, focused on two dimensions that matter most for voice agents: transcription latency and semantic accuracy.Our goal is specifically to evaluate STT performance for realtime voice agents. The best voice agents today can hear a user speak, transcribe their input, reason about a response, and begin generating audio in under a second. To hit that budget, every component in the pipeline needs to be fast.
