We proposed WhisperSeg, utilizing the Whisper Transformer pre-trained for Automatic Speech Recognition (ASR) for both human and animal Voice Activity Detection (VAD). For more details, please refer to our paper:

The model "nccratliri/whisperseg-base-animal-vad" is the checkpoint of the multi-species WhisperSeg-base that was finetuned on the vocal segmentation datasets of five species.
git clone https://github.com/nianlonggu/WhisperSeg.git
cd WhisperSeg; pip install -r requirements.txt
Then in the folder "WhisperSeg", run the following python script:
from model import WhisperSegmenter
import librosa
import json
segmenter = WhisperSegmenter( "nccratliri/whisperseg-base-animal-vad", device="cuda" )
sr = 32000
spec_time_step = 0.0025
audio, _ = librosa.load( "data/example_subset/Zebra_finch/test_adults/zebra_finch_g17y2U-f00007.wav",
sr = sr )
## Note if spec_time_step is not provided, a default value will be used by the model.
prediction = segmenter.segment( audio, sr = sr, spec_time_step = spec_time_step )
print(prediction)
{'onset': [0.01, 0.38, 0.603, 0.758, 0.912, 1.813, 1.967, 2.073, 2.838, 2.982, 3.112, 3.668, 3.828, 3.953, 5.158, 5.323, 5.467], 'offset': [0.073, 0.447, 0.673, 0.83, 1.483, 1.882, 2.037, 2.643, 2.893, 3.063, 3.283, 3.742, 3.898, 4.523, 5.223, 5.393, 6.043], 'cluster': ['zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0', 'zebra_finch_0']}
Visualize the results of WhisperSeg:
from audio_utils import SpecViewer
spec_viewer = SpecViewer()
spec_viewer.visualize( audio = audio, sr = sr, min_frequency= 0, prediction = prediction,
window_size=8, precision_bits=1
)
Run it in Google Colab: For more details, please refer to the GitHub repository: https://github.com/nianlonggu/WhisperSeg
