* feat(parakeet-cpp): implement the VAD call and add the vad_model option The backend now serves the VAD gRPC call (POST /vad and /v1/vad) with the standalone VAD of libparakeet. It accepts a Silero VAD GGUF as the model file, or an ASR model with a VAD head (Moondream Ultra and Redux). The request audio is float32 PCM at 16 kHz; the response lists the speech segments in seconds, like the silero-vad backend. A model with neither fails the request with the library message. The vad_threshold, vad_min_pause, vad_min_speech, vad_speech_pad and vad_max_segment options tune the segmenter. Unset values keep the defaults of the detector in use, and a bad value fails the load. The vad_model option names a Silero GGUF, resolved against the models directory like the other companion files. It lets any ASR model cut long audio at pauses through parakeet_capi_transcribe_path_json_vad_with, and it implies vad. vad:true alone still uses the model's own head. The new symbols are probed like the existing optional ones. A library without them still loads; the feature that needs one fails with a clear message only when it is used.

The parakeet-cpp-vad entry installs Silero; it has no variants, because variant ranking prefers the larger build that fits and these are different detectors. Add parakeet-cpp-tdt-0.6b-v3-silero-vad, a v3 entry that sets vad_model so long audio is cut at pauses by Silero. The Silero GGUF entries point at the intended Hugging Face URL of the file; the existing silero-vad entries are unchanged. A test checks the usecases, the shared files and the default entry and the vad_model reference. Assisted-by: Claude:claude-sonnet-5-5 [go test] * docs: describe parakeet-cpp VAD and the vad_model option Document the VAD endpoint on the parakeet-cpp backend (Silero GGUF and the VAD heads of Moondream Ultra and Redux), the vad_* tuning options, and the vad_model option that lets an ASR model without a VAD head cut long audio with Silero. Assisted-by: Claude:claude-sonnet-5-5 * chore(parakeet-cpp): bump parakeet.cpp to 6165e3d Pin the release that adds the standalone VAD (Ultra/Redux head and Silero) and the C API calls the backend now uses.
