This paper deals with implementing an efficient optimization technique for designing an Automatic Speaker Recognition (ASR) System, which uses average F-ratio score of TESPAR(Time Encoded Signal Processing And Recognition) and MFCC(Mel frequency Cepstral Coefficients) features, to yield high recognition accuracy even in adverse noisy conditions. A new ranking scheme is also proposed in order to...

requires a robust feature extraction unit followed by a speaker modeling scheme for generalized representation of these features. Over the years, Mel-Frequency Cepstral Coefficients (MFCC) modeled on the human auditory system has been used as a standard acoustic feature set for speech related applications. On a recent contribution by authors, it has been shown that the Inverted Mel-Frequency Ce...

In this paper, robust front end features are proposed for improvement in speaker identification (SI) performance by considering the factors of real world situations, like mismatch between training and testing conditions. The most commonly used MFCC features are very much sensitive to effects such as channel and environment mismatch. Characteristics of speech gets changed with room acoustics, ch...

Speech recognition is an important field of digital signal processing. Automatic Speaker Recognition (ASR) objective is to extract features, characterize and recognize speaker. Mel Frequency Cepstral Coefficients (MFCC) is most widely used feature vector for ASR. MFCC is used for designing a text dependent speaker identification system. In this paper the DSP processor TMS320C6713 with Code Comp...

In this paper our main aim to provide the difference between cepstral and non-cepstral feature extraction techniques. Here we try to cover-up most of the comparative features of Mel Frequency Cepstral Coefficient and prosodic features. In speaker recognition, there are two type of techniques are available for feature extraction: Short-term features i.e. Mel Frequency Cepstral Coefficient (MFCC)...

The purpose of this paper is to describe the work carried out for the Violent Scenes Detection task at MediaEval 2013 by team TUDCL. Our work is based on the combination of visual, temporal and audio features with machine learning at segment-level. Block-saliency-map based dense trajectory is proposed for visual and temporal features, and MFCC and delta-MFCC is used for audio features. For the ...

This paper proposes a Mel Frequency Cepstral Coefficient (MFCC) based hybrid algorithm for motor imagery classification of Electroencephalogram (EEG) signal for Brain Computer Interface (BCI). The proposed hybrid algorithm contains MFCC with Hjorth Parameter. Regression coefficient method was used for eye artifacts cancellation. The feature extraction method based on the difference of the diffe...

This full abstract describes our submitted system for the MIREX08 Audio Genre Classification task, the goal of which is to discriminate music excerpts of different genres/styles. The system is based on basic feature of MFCC and modeling framework of GSV-SVM, which has been successfully applied in speaker recognition field. In this submission, the only basic feature we use is MFCC. And the goal ...

Due to the increasing use of fusion in speaker recognition systems, one trend of current research activity focuses on new features that capture complementary information to the MFCC (Mel-frequency cepstral coefficients) for improving speaker recognition performance. The goal of this work is to combine (or fuse) amplitude and phase-based features to improve speaker verification performance. Base...

Speech synthesis and voice conversion techniques can pose threats to current speaker verification (SV) systems. For this purpose, it is essential to develop front end systems that are able to distinguish human speech vs. spoofed speech (synthesized or voice converted). In this paper, for the ASVspoof 2015 challenge, we propose a detector based on combination of cochlear filter cepstral coeffici...
