Synthesis of speech from text

摘要

An apparatus for synthesizing speech from text includes a language processing section which determines an accent environment of each mora of the text. In a basic accent pattern table, a basic accent pattern is classified according to the accent environment of the mora. The basic accent pattern includes a pitch data which is edited from real voice data according to the accent environment. A basic accent pattern processing section selects the basic accent pattern of each more from the basic accent pattern table according to the accent environment and processes the basic accent pattern in pitch according to the accent environment. A correcting section receives the corrected pitch data in the basic accent patter processing section and corrects the corrected pitch data according to the number of mora in each phrase and the position of the mora in phrase so as to correct the data into the corrected accent component. A phrase pattern processing section determines a phrase component according to the number of mora in each phrase which is of the accent environment. A speech synthesizing section synthesizes speech according to an accent control pattern of the text which is obtained by adding the accent pattern and the phrase pattern.
