Multi-voice Text-to-Speech System
Introduction
The text-to-speech (TTS) system converts any computer
readable text into human-like synthetic speech. The
TTS system is composed of three basic parts: linguistic,
phonetic, and acoustic module. The Text Analysis Module
converts the input text into a phonetic transcription
through morphological and syntactic analysis. The module
accesses a dictionary that has occurrence frequency
information extracted from the text corpus. The Korean
text analysis module performs two tasks: Korean sentence/Eojeol
segmentation; and Korean morphological/syntactic analysis.
The Prosody Generation Module predicts segmental duration
and amplitude of each phoneme, and pitch contour of
the input sentence. The module uses prosody rules extracted
from the speech corpus. The Korean prosody generation
modules performs three tasks: Prosodic phrasing; Predicting
phoneme duration/amplitude; and Predicting fundamental
frequency contour of a sentence. The Waveform Synthesis
Module generates synthetic speech signals by selecting
and concatenating synthesis units. The module modifies
the synthesis units to fit predicted duration, amplitude,
and pitch. Specifications: Operating System: Windows/95/98/NT,
UNIX Hardware: IBM compatible 486DX2 or above Minimum
