Voice biometric feature using Gammatone filterbank and ICA

Gammatone auditory filterbank and independent component analysis for speaker identification

Feature extraction is the key procedure when aiming at robust speaker identification. The most commonly used feature extraction techniques work successfully only in clean or matched environments. Accurate speaker identification is made difficult due to a number of factors, with handset/channel mismatch and environmental noise being the most prominent. This paper presents a novel technique which...

Gammatone Auditory Filterbank and Independent Component Analysis for Speaker Identification systems

ABSTACT Speaker identification is the process of recognizing who is speaking on the basis of information extracted from the speech signal. It has a number of applications in security and voice controlled service area. However, the most commonly used speaker recognition techniques work successfully only in clean or matched environment. Accurate speaker identification is made difficult due to a n...

Personal Recognition Using ICA

Independent Component Analysis (ICA) has been recently used to find representation of images with neurophysiological plausibility. Here we extended it to the problem of extract features suitable for personal identification from both face images and speech signal. A two-channel biometric system is presented in this paper. Both the face recognition module and voice recognition subsystem of it are...

Selective gammatone filterbank feature for robust sound event recognition

This paper introduces a novel feature based on the raw output of the gammatone filterbank. Channel selection is used to enhance robustness over a range of signal-to-noise ratios (SNR) of additive noise. The recognition accuracy of the proposed feature is tested on a sound event database using a Hidden Markov Model (HMM) recogniser. A comparison with a series of similar features and the conventi...
