The Efficiency of Different Formant Parameters for Speaker Discrimination

Original language description

This study examines the efficiency of different ways of capturing vowel formants for speaker discrimination. It compares the speaker-discriminating potential of static (F1-F4) and dynamic formant values (F1-F3), and assesses the usefulness of long-term formant distribution (LTF of F1-F4) for discriminating 16 female speakers of Czech. The results show that dynamic parameters overall perform slightly better than static ones; the most useful parameter of all is static F4. The study found no systematic differences in discriminability of speakers with regards to the position of word stress, i.e. speaker-specific information can be present in stressed as well as unstressed syllables. LTF seems to be a promising complement to the segment-based methods as itprovides an overall picture of the behaviour of each formant. The distribution of all four formants (especially F4) has been shown to have some speaker-discriminating potential, which has been assessed both visually and statistically.
