Speech synthesis system and its method
First Claim
1. A speech synthesis system having a word lexicon stored in a storage device for managing word information, a speech lexicon stored in the storage device for managing speech data, a language processing module carrying out language processing of an input text by using said word information, an acoustic processing module generating a synthesized speech signal by using said speech data in response to a processing result of the language processing module, and a D/A converter converting the synthesized speech signal to an analog signal, the system comprising:
- a detection module detecting, before inputting of the input text to be speech-synthesized and without depending thereupon, at least one of performance and conditions of a hardware part of a computer in which said speech synthesis system is implemented; and
an adjustment module adjusting at least one of said word information and said speech data to be given to said language processing module and said acoustic processing module, based on a detection result of said detection module to make speech-synthesis processing suitable for detected computer hardware conditions.

Abstract
A speech synthesis system has a word lexicon stored in a storage device for managing word information, a speech lexicon stored in the storage device for managing speech data. A language processing module carries out language processing of an input text by using the word information, and an acoustic processing module generates a synthesized speech signal by using the speech data in response to a processing result of the language processing module. A D/A converter converts the synthesized speech signal to an analog signal. The system further includes a detection module detecting performance or conditions of a hardware part of a computer in which the system is implemented, and an adjustment module adjusting the word information and/or the speech data which are to be given to the language processing module and the acoustic processing module, based on a detection result of the detection module. Therefore, an optimum speech-synthesis processing suitable for any computer is performed.
