Unlimited Vocabulary Synthesis Using Line Spectrum Pairs
In: DTIC AND NTIS (1991)
Abstract: This report describes a new speech synthesis system based on the line spectrum pair (LSP) representation of the speech signal. The system includes a library of approximately 250 stored speech segments, represented by LSP parameters, that are concatenated to produce an unlimited output vocabulary. All components of the system are discussed, and particular emphasis is placed on the methods used to adjust the pitch, duration, and amplitude of concatenated segments to generate natural sounding speech. A new method of computing fundamental frequency contours for sentential intonation patterns is presented. Test results show good segmental intelligibility for the synthesized speech: a score of 86.3 was obtained on the Diagnostic Rhyme Test (DRT); a score of 86.7 was obtained on the Modified Rhyme Test (MRT).
