pyannotevoice-activity-detection
PyannoteVAD¶
Applies pyannote VAD with separate onset and offset thresholds.
Parameter metadata: Not reported: the audited metadata available for the registered default does not provide an exact parameter total.
Usage¶
Complete the VoiceHub installation once, then run this repository-authored example. Model pages intentionally contain no package-install command.
This example is maintained against VoiceHub's public API; it is not copied from an upstream demo or package README.
Model-specific path: Applies pyannote VAD with separate onset and offset thresholds.
Inputs and controls: The repository can be gated; authenticate through the normal Hugging Face token flow before loading.
from pathlib import Path
from voicehub import AutoModelForVoiceActivityDetection
AUDIO_FILE = Path("speech.wav")
if not AUDIO_FILE.is_file():
raise FileNotFoundError(AUDIO_FILE)
model = AutoModelForVoiceActivityDetection.from_pretrained(
'pyannote/voice-activity-detection',
model_type='vad_pyannote',
device="cpu",
lazy_load=True,
)
output = model.detect(
AUDIO_FILE,
onset=0.55,
offset=0.45,
min_speech_duration_ms=100,
)
for segment in output.segments:
print(segment.start, segment.end, segment.score)
Use authorized recordings. Verify hardware needs and pin a revision in production.
Overview¶
vad_pyannote is a VoiceHub voice activity detection
integration. This page is generated from its registry contract. Open the vad_pyannote Colab notebook.
| Property | Value |
|---|---|
| Task | Voice activity detection |
| Architecture | pyannet |
| Runtime | VoiceHub-native |
| Languages | Not text-language conditioned |
| Capabilities | voice-activity-detection, voicehub-native, gated-checkpoint, trusted-checkpoint-conversion, safetensors, frame-scores, fine-tuning |
| Reusable components | — |
| Normalized output | VADOutput |
Language support¶
The public VAD contract does not select a spoken language; validate checkpoint acoustic coverage on the target languages and recording conditions.
Paper and GitHub¶
- Paper: pyannote.audio: neural building blocks for speaker diarization
- Upstream GitHub: pyannote.audio
- VoiceHub source: VoiceHub model implementation
Configuration¶
Load configuration without constructing the model:
from voicehub import AutoConfig
config = AutoConfig.for_model('vad_pyannote')
print(config.model_type)
| Property | Value |
|---|---|
| Canonical model type | vad_pyannote |
| Configuration class | PyannoteVADConfig |
| Architecture class | PyannoteVADForVoiceActivityDetection |
Processing¶
Create the registered processor without allocating model weights:
from voicehub import AutoProcessor
processor = AutoProcessor.from_pretrained(
'pyannote/voice-activity-detection',
model_type='vad_pyannote',
)
print(type(processor).__name__)
Inference¶
The Usage example returns VADOutput through AutoModelForVoiceActivityDetection.
Input and output contract¶
| Property | Value |
|---|---|
| Label boundary | Clip-, frame-, or segment-level labels |
| Required training inputs | waveforms, labels |
Use authorized audio and preserve annotation provenance. See the ASR and VAD data workflow.
Training and optimization¶
Use available_optimization_passes() to discover reversible public passes.
Unsupported runtime or hardware fails closed before mutation.
Training contract¶
| Property | Value |
|---|---|
| Support | native |
| Family | frame-classification |
| Recipe | single-phase |
| Default phase | segmentation |
| Training checkpoint | pyannote/voice-activity-detection |
| Native training graph | yes |
| Phase | Kind | Components | Required inputs | Loss keys |
|---|---|---|---|---|
segmentation |
objective | model |
waveforms, labels |
loss |
The integration accepts its declared source or prepared contract directly. Call model.validate_training_support() first, then follow the
training workflow.
Checkpoints, provenance, license, and limitations¶
| Property | Value |
|---|---|
| Default checkpoint | pyannote/voice-activity-detection |
| Hugging Face ID | pyannote/voice-activity-detectionRepository availability verified through the Hugging Face model API on 2026-08-11; pin a revision before production use. |
| Checkpoint status | Registry default; pin an immutable revision for production and reproducible evidence |
| Optional dependency extra | Core package |
| Hardware and runtime | Usage selects cpu; verify checkpoint-specific requirements |
| Real-checkpoint evidence | Release evidence; a registry default alone is not execution evidence |
| Implementation | voicehub.models.vad_pyannote.modeling_vad_pyannote.PyannoteVADForVoiceActivityDetection |
| Configuration | voicehub.models.vad_pyannote.configuration_vad_pyannote.PyannoteVADConfig |
| Source provenance | voicehub/architectures/pyannet/SOURCE.json |
| License | Checkpoint-specific |
No VoiceHub-specific license override is registered. Verify the checkpoint and upstream source terms before use.
Confirm the checkpoint revision, access terms, provenance, and license.
Limitations¶
- No integration-specific checkpoint limitation is registered. Verify the selected checkpoint revision and its documented runtime requirements.
- Validate memory, precision, and optional dependencies on the target system.
- Public optimizations fail closed when the runtime or hardware cannot satisfy their validation contract; an unavailable pass is not reported as applied.
- Contract tests do not replace the linked released-checkpoint evidence.
