Paper Abstract

We argue that when individuals enunciate sounds which are perceived to be the same, the sounds have the commonalty that their spectra can be transformed into a new domain which results in identical spectra except for a speaker dependent translation factor. We call the transformation function the speech scale. The speech scale is experimentally obtained. In this paper we explore the mathematical issues involved and obtain various criteria for when a transformation to a new domain results in a speaker independent transform.
