/ 100
Established

Extends Kaldi's dynamic grammar compilation to enable per-utterance activation/deactivation of individual rules, allowing context-aware recognition that improves accuracy by constraining the active grammar set. Bundles pre-compiled binaries for Windows/Linux/macOS and includes a general English nnet3 chain model trained on ~3000 hours of audio, plus native integration with the Dragonfly speech recognition framework for command-and-control applications.
