Subject: Principal components analysis From: Stuart Rosen <stuart(at)PHONETICS.UCL.AC.UK> Date: Mon, 15 Mar 1993 10:56:10 GMT------------------------------------------------ A number of workers in the Netherlands used principal components to great effect on vowel spectra in the 60's and 70's. These are reviewed in brief (along with the psychoacoustical background) on pp 427-431 of: Rosen, S. & Fourcin, A.J. (1986) Frequency selectivity and the perception of speech. In: Frequency Selectivity in Hearing, ed. B.C.J. Moore. London: Academic Press, pp 373-487. The main papers I know about are (although perhaps not the last 2 - I'm just not sure): Pols, L. C. W., Kamp, L. J. Th. van der, and Plomp, R. (1969). Perceptual and physical space of vowel sounds, J. Acoust. Soc. Am., 46, 458-467. Plomp, R., Pols, L. C. W. and Geer, J. O. van der (1967). Dimensional analysis of vowel spectra, J. Acoust. Soc. Am., 41, 707-712. Klein, W., Plomp, R., and Pols, L. C. W. (1970). Vowel spectra, vowel spaces and vowel identification, J. Acoust. Soc. Am., 48, 999-1009. Nierop, D. J. P. J. van, Pols, L. C. W. and Plomp, R. (1973). Frequency analysis of Dutch vowels from 25 female speakers, Acustica, 29, 110-118. Pols, L. C. W., Tromp, H. R. C. and Plomp, R. (1973). Frequency analysis of Dutch vowels from 50 male speakers, J. Acoust. Soc. Am., 53, 1093-1101. Yours - Stuart Rosen
