chappie-kws

Mirror of k2-fsa's sherpa-onnx-kws-zipformer-gigaspeech-3.3M-2024-01-01 (int8), carrying only the five files sherpa-onnx's KeywordSpotter loads.

Used as the wake-word model for Chappie, a Reachy Mini robot. Mirrored here because the upstream model is published only as a GitHub release tarball, and the robot app fetches its model with huggingface_hub.snapshot_download.

Upstream: https://github.com/k2-fsa/sherpa-onnx/releases/tag/kws-models License: Apache-2.0, unchanged from upstream.

Note: this model is phase-sensitive — it emits a verdict only on a decode grid anchored to the stream's first sample (period 16 chunks at 100ms/chunk), so an utterance's detectability depends on its alignment to that grid. Consumers that restart a stream mid-conversation should replay a few hundred ms of lookback into the fresh stream.
