Patent

CA 2614840

The present invention relates to the provision of natural-soundingphonemes and accents for text. There is provided a system that outputs phonemes and accents of texts.The system has a storage section storing a first corpus in which spellings, phonemes, and accents of a text input beforehand are recorded separately for individual segmentations of the words that are contained in the text. A text for which phonemes and accents are to be output is acquired and the first corpus is searched to retrieve at least one set of spellings that match the spellings in the text from among sets of contiguous spellings. Then, the combination of a phoneme and an accent that has a higher probability of occurrence in the first corpus than a predetermined reference probability is selected as the phonemes and accent of the text.

Fourniture de phonèmes et d'accents dont la perception paraît naturelle, pour du texte. On décrit un système qui fournit ces phonèmes et accents en liaison avec du texte. Le système comporte un étage d'enregistrement qui enregistre un premier corpus dans lequel des orthographes, des phonèmes et des accents de texte saisi à l'avance sont enregistrés séparément pour des segmentations individuelles relatives aux mots que contient le texte. Un texte pour lequel des phonèmes et accents doivent être fournis est acquis et le premier corpus est exploré à la recherche d'au moins une série d'orthographes correspondant aux orthographes dans le texte, parmi les séries d'orthographes contiguës. Ensuite, la combinaison d'un phonème et d'un accent présentant une probabilité d'occurrence plus élevée dans le premier corpus qu'une probabilité de référence préétablie est choisie pour phonème et accent dans le texte.
