Abstract
In this paper, an approach based on Kekre‟s fast code book Generation (KFCG) Algorithm in the transform domain has been proposed. KFCG is used for feature extraction in both the training and testing phases. Three methods for codebook generation have been used. In the 1 st method, codebooks are generated from the speech samples by using Discrete Fourier Transform (DFT). In the 2 nd method, the codebooks are generated using Discrete Cosine Transform (DCT). In the 3 rd method, the codebooks are generated using the Discrete Sine Transform (DST). For speaker identification, the codebook of the test sample is similarly generated and compared with the codebooks of the reference samples stored in the database. The results obtained for the above methods in the transform domain are compared with the results obtained in the time domain analysis. The results show that KFCG gives better results in transform domain than in time domain. Also the results improve as the vector dimension while generating the codebook is increased.
