Automatic segmentation of speech ir on important problem that is useful in speed recognition, synthesis and coding. We explore in this paper: the robust parameter set, weightingfunction and distance measure for reliable segmentation of noisy speech. It is found that the MFCC parometers, successful in speech recognition. holds the best promise far robust segmentation also. We also explored a variery of symmetric and asymmetric weighting lifter, from which it is found that a symmetric lifter of the form $1+{Asin^{1/2}}{(\pi n/L)}$, ${0}\leq{n}\leq{L-1}$, for MFCC dimension L, is most effective. With regard to distance measure. the direct $L_2$ norm is found adequate.
