2、ity, Nanjing 210093, China E-mail: jlu Abstract: Speech segmentation is the foundation of some applications such as speech recognition and spoken document retrieval. An improved algorithm is proposed here which include: (1 GLR variance based threshold adaptive algorithm is to improve the threshold s

3、election approach in speaker based speech segmentation under various acoustic environments;(2 BICs Detection Ability is referred to determine when BIC is effective;(3 Besides to verify the candidate segmentation points, BIC is used to calibrate their bias caused by GLR variance. Experimental results

4、 indicate that the improved algorithm is prior to the original one. Key words: speaker-based speech segmentation; Bayesian information criterion (BIC; generalized likelihood ratio (GLR; mel-frequency cepstral coefficient (MFCC; hypothesis testing á Received May 10, 2000; accepted August 3, 2000
