- W3003199575 abstract "Speaker identification (SID) systems need to be robust to extrinsic variations in the speech signal, such as background noise, to be applicable in many real-life scenarios. Mel-frequency cepstral coefficient (MFCC)-based i-vector systems have been defined as the state-of-the-art technique for speaker identification, but it is well-known that the performance of traditional methods, in which features are mostly extracted from the properties of the acoustic signal, degrades substantially under noisy conditions. This study proposes a robust SID system using the neural responses of a physiologically-based computational model of the auditory periphery. The 2-D neurograms were constructed from the simulated responses of the auditory-nerve fibers to speech signals from the TIMIT database. The neurogram coefficients were trained using the i-vector based systems to generate an identity model for each speaker, and performances were evaluated and compared in quiet and under noisy conditions with the results from existing methods such as the MFCC, frequency-domain linear prediction (FDLP) and Gammatone frequency cepstral coefficient (GFCC). Results showed that the proposed system outperformed all existing acoustic-signal-based methods for both in quiet and under noisy conditions." @default.
