Abstract

|
In this paper, we propose two kinds of chaos dimensions, they fuzzy correlation and fuzzy Lyapunov dimensions, for speaker necognition. The proposal is based on the point that chaos enables us to analyze the non-linear information contained in individual´s speech signal and to obtain superior discrimination capability.
We confirm that the proposed fuzzy chaos dimensions play an important role in enhancin speaker recognition ratio, by absorbing the variations of the reference and test pattern attractors.
In order to evaluate the proposed fuzzy chaos dimensions, we suggest speaker recognition using the proposed dimensions. In other words, we investigate the validity of the speaker recognition parameters, by estimating the recognition error according to the discriminnation error of an individual speaker from the reference pattern.
Keywords : speaker recognition, fuzzy chaos dimensions, discrimination error
