oto

oto builds the datasets, models, and benchmarks that voice AI labs use to ship full-duplex speech-to-speech systems. Real two-channel conversation, end to end.

Every record oto accepts produces an immutable receipt on Trace. Everything below is read live from those receipts — nothing here is self-reported.
