The Agentic Data Company released Open Yap 1K, billed as the world's largest free conversational speech dataset: 1,000 hours (1,602 conversations, 239 speakers) of natural English two-speaker audio at 48 kHz dual-channel, free for commercial and research use. Unlike Fisher or Switchboard, speakers are friends/family talking freely, preserving interrupts, backchannels, and short turn gaps that full-duplex models must learn. Transcriptions are word-level from Deepgram Nova-3 (not human-verified), and it's part of a larger licensed corpus built with frontier labs.
