Speech Synthesis by a Programmable Digital Filter.

Abstract

An automatic technique was developed to produce recognizable speech from a string of phonetic characters input from a teletype. The technique is based on modeling the acoustical consequences of the various configurations of the vocal tract. The scheme was tested by acoustical feedback (i.e. listening to it) and by the use of the Speech Analysis System developed by the Aerospace Medical Research Laboratory. The Speech Analysis System consists of an analyzer and associated equipment necessary to produce a real-time hardcopy representation of the frequency characteristics of the speech input. The analyzer itself is called a COC filter and its design is based on the hydro-mechanical operation of the inner ear.
