F0 and F1

[Pierre Divenyi <pdivenyi@xxxxxxxxx>]

Dear List,

Our colleague Jean-Sylvain
Liénard (Paris) asked me to post this
note for him.

Best,

Pierre

Dear Daniel,

    Increases of F0 and F1 are the most noticeable effects
of  an increase of voice intensity, i.e. vocal effort. You may get
some valuable info, as well as some earlier references, in the following
paper:

J.-S.LIENARD and M.-G. DI BENEDETTO  : "Effect of vocal effort
on spectral properties of vowels", Journal of the Acoustical Society
of America, 106 (1), 411-422, july 1999

    In my opinion, controlling the physical intensity of
voice production in a vowel perception experiment is a mandatory (though
often neglected)  precaution. It changes everything in the spectrum.

Yours cordially,

Jean-Sylvain
