Voice-Pishing Detection Algorithm Based on 3GPP2 SMV
Kye-Hwan Lee, Joon‐Hyuk Chang · Journal of the Institute of Electronics Engineers of Korea · 2008
We propose an effective voice-pishing detection algorithm based on the 3GPP2 selectable mode vocoder (SMV). The detection of voice pishing is performed based on a Gaussian mixture model (GMM) using decoding parameters of the SMV directly extracted from the decoding process of the transmitted speech information in the mobile phone. The experimental results indicate that SMV decoding parameters are effective in discriminating between general voice and phisher's voice and the performance is significantly acceptable when the proposed technique is applied.
