7th International Conference on Spoken Language Processing
September 16-20, 2002
In this study, we describe and evaluate a subjective test to determine the importance of subbands in perceiving the speaker identity. Pairs of sound files have been generated where the first sound file is the full-band version of a word and the second file is a subband of the same word in the first part and a subband of a different word in the second part of the experimental work. Words in each pair are uttered by either the same speaker or different speakers. Subjects were asked to score each pair of sound files they listened to according to the similarity of the speakers uttering each word. Also a consistency score is calculated for each subject to render the statistics more reliable. The experiment demonstrates that the second subband (1034 Hz-1895 Hz range) is the most important subband for speaker identification.
