Re: head directivity data & phoneme spectral statistic

[Pierre Divenyi <pdivenyi@xxxxxxxxx>]

Dear Zoltan,

If by "directivity function of the human head" you mean 
anthropometric data, there have been extensive measurements made on a 
fair number of subjects at the University of California CIPIC 
laboratory, by Ralph Algazi and Dick Duda. It would be best to 
contact them and ask them directly what in particular ou are interested in.

With regard to average spectral (spectro-temporal?) characteristics 
of English phonemes, in your place I would ask Jont Allen for his 
data or data he has been working with. The caveat of course is that 
no matter how precise those measurements may be, they go to pot in 
coarticulation and, more generally, in spontaneous and often sloppy 
spoken language. Beware of the phoneme -- it may be only a mirage!
