Apparatus for electronically generating a spoken message

Abstract

An improved apparatus for generating a spoken message is of the type formed by (i) first recording speech and (ii) then utilizing the recording so as to obtain at least one carrier, each carrier having at least one fixed part and at least one open slot, and then (iii) inserting an argument into each open slot. The improvement provides a phonetico-prosodic parameter generator for characterizing the message in terms of a sequence of phonetico-prosodic parameters for each carrier. An electronic memory stores the phonetico-prosodic parameters corresponding to each carrier and a controller constructs sequences of phonetico-prosodic parameters corresponding to the argument of each open slot. From the phonetico-prosodic parameters, a phonetics-to-speech converter generates a digital sound wave pattern which is converted, by a D/A converter, into an analog sound wave pattern. An output unit provides audible sound waves corresponding to the analog sound wave pattern. In a preferred embodiment, an input is provided for entering the arguments as orthographic or phonetic text which is converted to phonetico-prosodic parameters as well, so that the entire spoken message can be synthesized by a phonetics-to-speech system, resulting in enhanced consistency, even when the carriers are generated from the recording of different human subjects.
