Does anyone have any figures on the formant ranges? Schafer & Rabiner
(JASA-47:634-648 1970) quote for male speech:
	F1  200-900 Hz
	F2  550-2700 Hz
	F3  1100-2950 Hz
and I know that formant spacing has to be about 1kHz (from the resonances
of a uniform tube) but can anyone give me some pointers to formant
distributions observed in practice, preferably with F4 as well, or
even better a theoretical derivation of the formant ranges?

Cheers,

HB.
