Speech synthesis apparatus and method thereof

Abstract

A speech synthesis apparatus includes a text obtaining device that obtains text data for speech synthesis from the outside, a language processor that carries out morphological analysis / parsing to the text data, a prosodic processor that outputs, to a speech synthesizer, a synthesis unit string based on the prosodic and language related attributes of the text data such as accents and word classes, the speech synthesizer that generates synthesized speech from the synthesis unit string, and a speech waveform output device that reproduces a prescribed amount of output synthesized speech after it is accumulated or sequentially as it is output.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims the benefit of priority from a prior Japanese Patent Application No. 2006-92489 filed on May 29, 2006, the entire contents of which are hereby incorporated by reference. technical field [0003] The present application relates to a speech synthesis device, a speech synthesis method, and a speech synthesis program that allow speech to be synthesized from phonemic symbols such as phoneme symbols / syllable symbols or character sequences used in natural language representation. Background technique [0004] As described on pages 369-370 of the Proceedings of the 2004 Autumn Meeting of the Acoustical Society of Japan, it is known that increasing available waveform data is effective as a method of improving the sound quality of conventional speech synthesizers. The recommended solution for implementing this method is to distribute and use large amounts of waveform data between memory ...
