To obtain a text sentence selecting method for corpus-based speech synthesis which evaluates a quality index of a text sentence set while searching for suitable text sentences from an expanded range, and is small in computational amount.
The text sentence selecting method for corpus-based speech synthesis includes: a step of providing a thesaurus dictionary 110 containing synonyms of an object category of speech synthesis, selecting one arbitrary sentence from a text corpus, and selecting a text sentence (selected sentence) such that when the text is added to a work text sentence set, the corpus quality becomes maximum; a step of generating a similar sentence group by substituting synonyms that the thesaurus dictionary holds for words and phrases constituting the selected sentence; a re-decision step of selecting one arbitrary sentence from a group of sentences similar to the selected sentence and finding a text sentence (best sentence) such that when the sentence is added to the work text sentence set, the corpus quality becomes maximum; and a step of adding the best sentence obtained in the re-decision step to the work text sentence set.
