N2 - In this paper, line spectral frequencies (LSF) and five types of transformed LSF are studied for robust text-independent speaker identification. Transformations are constructed by considering the physical aspect of vocal tract. They are location of formants/nulls, bandwidth of formants/nulls, bandwidth and location of formants, bandwidth and location of nulls, and interval of adjacent formant and null location. Identification tests using TIMIT database verify that all features are useful for speaker recognition, especially the bandwidth and location of formants show the best performance. Simulation results also show that LSF and some of transformed LSF give better performance than MFCC.
