+# Voice Activity Detection with Overlap Detection
+
+This project uses the WebRTC VAD module to perform Voice Activity Detection (VAD) on an audio file. It also applies noise reduction to the audio file before performing VAD.
+
+## Dependencies
+
+- Python 3
+- numpy
+- librosa
+- matplotlib
+- webrtcvad
+- soundfile
+- noisereduce
+
+You can install these dependencies using pip:
+
+```bash
+pip install numpy librosa matplotlib webrtcvad soundfile noisereduce
+```
+
+or
+
+```bash
+pip install -r requirements.txt
+```
+
+## Usage
+
+1. Clone the repo
+
+```bash
+    git clone https://github.com/Manoj-2702/FacialAnalysis-IISc.git
+```
+
+2. Navigate to the directory
+
+```bash
+    cd FacialAnalysis-IISc/OverlappedSpeech
+```
+
+3. Run the script
+
+```
+    python vad.py
+```
+
+```python
+from vad import vad_with_overlap_detection
+
+# Replace 'your_audio_file.wav' with the path to your audio file
+audio_file_path = 'your_audio_file.wav'
+
+# Run VAD with overlap detection and plot the graph
+vad_with_overlap_detection(audio_file_path)
+
+```
+
+4. The output will be a graph showing the overlapping speech regions.
+
+## Audio File
+
+Sample audio file is in this repo. iisc_1.mp3
