Speaker identification using discriminative features selection
نویسندگان
چکیده
A new method of text-dependent speaker identification using discriminative feature selection is proposed in this paper. The characteristics of the proposed method are as follows: feature parameters extraction, vector quantization with the growing neural gas (GNG) algorithm, model building using gaussian distributions and discriminative feature selection (DFS) according to the uniqueness of personal features. The speaker identification algorithm is evaluated on a database that includes 25 speakers each of them recorded in 12 different sessions. All speakers spoke the same phrase for 10 times in each recording session. The test results showed that both FRR (False Rejection Rate) and FAR (False Acceptance Rate) were about 1[%].

In-set/out-of-set speaker identification based on discriminative speech frame selection
In this paper, we propose a novel discriminative speech frame selection (DSFS) scheme for the problem of in-set/out-of-set speaker identification, which seeks to decrease the similarity between speaker models and background model (or antispeaker model), and increase the accuracy of speaker identification. The working scheme of DSFS consists of two steps: speech frame analysis and discriminative...
متن کاملDimension reduction for speaker identification based on mutual information
Dimension reduction is a necessary step for speech feature extraction in a speaker identification system. Discrete Cosine Transform (DCT) or Principal Component Analysis (PCA) is widely used for dimension reduction. By choosing basis vectors from basis vector pool of DCT or PCA which contribute more to data distribution variance or reconstruction accuracy of speech data set, we can transform th...

متن کاملDiscrimination Analysis of Lip Motion Features for Multimodal Speaker Identification and Speech-reading
In this thesis a new multimodal speaker/speech recognition system that integrates audio, lip texture, lip geometry, and lip motion modalities is presented. There have been several studies that jointly use audio, lip intensity and/or lip geometry information for speaker identification and speech-reading applications. This work proposes using explicit lip motion information, instead of or in addi...
متن کاملComparison of Clustering Algorithms for Speaker Identification
In this paper we consider the problem of text-independent speaker identification that refers to acoustic recognition research. Many different techniques have been presented over past several decades. A stateof-the-art technique uses Gaussian Mixtures (GMM) for modeling speaker data distribution presented by MFCC [1] or LPCC [2] features. The classification is obtained by choosing the speaker cl...
