Re: Origin of the Mel frequency scale equation?

["N.H. Zheng" <nhzheng@xxxxxxxxxxxxxx>]

An earlier paper describing the Mel frequency is:
Comparison of Parametric Representations for Monosyllabic Word Recognition 
in Continuously Spoken Sentences
IEEE TRANSACTIONS ON ACOUSTICS, SPEECH, AND SIGNAL PROCESSING, VOL. ASSP-28, 
NO. 4, AUGUST 1980 pp.357
