About 80% of 31,663 labels were considered to represent English phonemes. A database of British English spoken sentences was used for the present analysis, because each identifiable speech sound was indicated in the speech waveform with a label of a phonetic symbol. Factor analyses were performed on the power fluctuations of the outputs of 19 critical-band filters, which separated British English sentences uttered by two female speakers and one male speaker into narrow-band signals. The acoustic sonority could be related to a few phonological phenomena: 1) A sonorant consonant immediately after an obstruent can be a syllable nucleus, 2) a consonant cluster at the beginning of a word mostly begins with an obstruent, and 3) a short schwa cannot be a nucleus of a stressed syllable.Ībstract = "Our previous study on British English speech was extended into the domain of phonology. Three factors appeared as in our previous research, and one of them corresponding to a frequency range of about 500-1700 Hz was closely related to sonority or aperture described in linguistics literature. Our previous study on British English speech was extended into the domain of phonology.
