Speech synthesis system and its method

A speech synthesizing method, comprising the steps of:

• (a) detecting, before inputting of an 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 a speech synthesis system is constructed;
• (b) adjusting, based on a detection result of said performance or said conditions, word information which is derived from a word lexicon and is given to a language processing module and speech data which is derived from a speech lexicon and is given to an acoustic processing module;
• (c) performing language processing for speech synthesis of the input text by using adjusted word information;
• and
• (d) generating a synthesized speech signal of the input text by using adjusted speech data, in response to a result of the language processing.

A speech synthesizing method, comprising the steps of:

• (a) setting at least one of performance and conditions of a hardware part of a computer in which a speech synthesis system is constructed, by a dialogic processing between a user and the computer, before inputting of the input text to be speech-synthesized and without depending thereupon;
• (b) adjusting, based on a setting result of said performance or said conditions, word information which is derived from a word lexicon and is given to a language processing module and speech data which is derived from a speech lexicon and is given to an acoustic processing module;
• (c) performing language processing for speech synthesis of an input text by using adjusted word information;
• and
• (d) generating a synthesized speech signal of the input text by using adjusted speech data, in response to a result of the language processing.

A storage medium storing information and data describing a sequence for controlling a speech synthesis system, the storage medium comprising:

• a word lexicon managing word information;
• a speech lexicon managing speech data;
• a language processing module performing language processing for speech synthesis of an input text by using word information of the word lexicon;
• an acoustic processing module generating a synthesized speech signal of the input text by using speech data of the speech lexicon, based on a processing result of the language processing module;
• 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 system is implemented;
• and
• an adjustment module adjusting lexicon information which is to be given to said language processing module and said acoustic processing module, in response to a detection result of said detection module.
