In this paper, hum of a person is used in voice biometric system. In addition, recently proposed feature set, i.e., Variable length Teager Energy Based Mel Frequency Cepstral Coefficients (VTMFCC), is found to capture perceptually meaningful source-like information from hum signal. For person recognition, MFCC gives EER of 13.14% and %ID of 64.96%. A reduction in equal error rate (EER) by 0.2% ...

Information world meet many confronts nowadays and one such, is data retrieval from a multidimensional and heterogeneous data set. Han & et al carried out a trail for the mentioned challenge. A novel feature co-selection for web document clustering is proposed by them, which is called Multitype Features Co-selection for Clustering (MFCC). MFCC uses intermediate clustering results in one type of...

In this paper, we continue our investigation of the warped discrete cosine transform cepstrum (WDCTC), which was earlier introduced as a new speech processing feature [1]. Here, we study the statistical properties of the WDCTC and compare them with the mel-frequency cepstral coefficients (MFCC). We report some interesting properties of the WDCTC when compared to the MFCC: its statistical distri...

The Mel-frequency cepstral coefficients (MFCC) are commonly used in speech recognition systems. But, they are high sensitive to presence of external noise. In this paper, we propose a noise compensation method for Mel filter bank energies and so MFCC features. This compensation method is performed in two stages: Mel sub-band filtering and then compression of Mel-sub-band energies. In the compre...

Log area ratio coefficients (LAR) derived from linear prediction coefficients (LPC) is a well known feature extraction technique used in speech applications. This paper presents a novel way to use the LAR feature in a speaker identification system. Here, instead of using the mel frequency cepstral coefficients (MFCC), the LAR feature is used in a Gaussian mixture model (GMM) based speaker ident...

This paper evaluates the impact of low-level features on speaker verification performance, with an emphasis on the recently proposed MFCC variant based on asymmetric tapers (MFCC asymmetric from now on) standalone as features or followed by PCA as linear projection technique applied before the GMM-UBM back-end classifier in clean and noisy environments. The performances of the MFCC-asymmetric f...

Eigen-MLLR coe cients are proposed as new feature parameters for speaker-identi cation in this paper. By performing principle component analysis on MLLR parameters among training speakers, the eigen-MLLR coe cients (EMCs) are derived as the coe cients for the eigenvectors. The discriminating function of the new EMC features based on the Fisher criterion is found to be ten times larger than that...

This paper briefly describes the language recognition system developed by the Sofware Technology Working Group (http://gtts.ehu.es) at the University of the Basque Country in collaboration with IKERLAN Technological Research Center, and submitted to the NIST 2009 Language Recognition Evaluation. The system consists of a hierarchical fusion of individual subsystems: two acoustic GLDS-SVM systems...
