+# Positive Transfer Of The Whisper Speech Transformer To Human And Animal Voice Activity Detection
+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:
+> [**Positive Transfer of the Whisper Speech Transformer to Human and Animal Voice Activity Detection**](https://doi.org/10.1101/2023.09.30.560270)

+> University of Zurich and ETH Zurich
+
+*Accepted to the 2024 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP 2024)*
+
+
+The model "nccratliri/whisperseg-base-animal-vad-ct2" is the Ctranslate2 version of "nccratliri/whisperseg-base-animal-vad". It can only be used for faster inference. For finetuning the model, use "nccratliri/whisperseg-base-animal-vad" instead.
+
+The "xxx-ct2" model need to be loaded by WhisperSegmenterFast (instead of WhisperSegmenter)
+
+## Usage
+### Clone the GitHub repo and install dependencies
+```bash
+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:
+```python
+from model import WhisperSegmenterFast
+import librosa
+import json
+segmenter = WhisperSegmenterFast( "nccratliri/whisperseg-base-animal-vad-ct2", 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:
+```python
+from audio_utils import SpecViewer
+spec_viewer = SpecViewer()
+spec_viewer.visualize( audio = audio, sr = sr, min_frequency= min_frequency, prediction = prediction,
+                       window_size=8, precision_bits=1 
+                     )
+```
