Earlybird Predicts Speech Before Words End
Earlybird is a 29M-parameter, 16.8 MB on-device speech-to-text model that predicts words roughly 90 ms before they finish, with confidence scores for each token. Its open weights and code target latency-sensitive voice agents and edge deployments.
Earlybird makes negative-latency speech recognition practical, but its biggest value is giving agents an early, confidence-weighted signal rather than a transcript they must blindly trust.
- –Runs about twice real time on one CPU thread, making local deployment unusually accessible
- –Predicts 69% of audiobook words correctly before they end, substantially ahead of conventional streaming models
- –Confidence scores let developers decide when to prefetch, classify intent, or start planning
- –Early predictions can rewrite frequently, so production agents need provisional-text handling and commit policies
- –Accuracy falls sharply in background noise, and the model currently supports English only
