Voice activity detection based on complex Laplacian model
Joon‐Hyuk Chang, Nam Soo Kim · Electronics Letters · 2003
A voice activity detector (VAD) based on the complex Laplacian model is proposed. The likelihood ratio based on the Laplacian model is computed and then applied to the VAD operation. According to experimental results, it is found that the Laplacian statistical model is more efficient for the VAD algorithm compared to the Gaussian model.
