Speaker individualities in speech spectral envelopes

Tatsuya Kitamura, Masato Akagi

Physical characteristics representing speaker individualities embedded in the spectral envelopes of vowels are investigated through four psychoacoustic experiments. The LMA analysis-synthesis system is used to prepare stimuli varying specific frequency bands in the spectral envelopes and the frequency bands having speaker individualities are estimated. The experimental results suggest that speaker individualities mainly exist at above the 23.5 ERB rate (2340 Hz) in the spectral envelopes and that they can be controlled without influencing vowel identification. More detailed information on the spectral envelopes is required for speaker identification than for vowel identification.
