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 16MB RAM 152 MB free hard disk space Sound Card (supporting Microsoft Windows)
