You may get some valuable info, as=20 well as some earlier references, in the following paper: J.-S.LIENARD and M.-G. DI BENEDETTO : "Effect of vocal effort on spectral= =20 properties of vowels", Journal of the Acoustical Society of America, 106=20 (1), 411-422, july 1999 In my opinion, controlling the physical intensity of voice production= =20 in a vowel perception experiment is a mandatory (though often=20 neglected) precaution. It changes everything in the spectrum.
