A PROGRAM STRUCTURE FOR EVENT-BASED SPEECH SYNTHESIS BY RULES WITHIN A FLEXIBLE SEGMENTAL FRAMEWORK
Abstract
A program structure based on recently developed techniques
for operating system simulation has the required flexibility for use as a speech
synthesis algorithm research framework. Synthesis is possible with less
rigid time and frequency component structure than with simpler schemes,
and it allows much of the speech knowledge required for synthesis to be
removed from the main driving structure and embodied as tables and
procedures that may easily be modified or replaced. The program also
meets real time operation and memory size constraints. The resulting view of
speech structure, at the acoustic segmental level, is that of time ordered,
perceptually relevant events, and is related to that used in the
author's work on automatic speech pattern discrimination. The flexibility of the
scheme for synthesis, and the excellent mutual independence of the many
processes, with differing objectives, that must be run for realistic
approximations to real speech variation, have proved a welcome release
from earlier problems. The author acknowledges with gratitude the
support of the National Research Council of Canada.
