PURPOSE: To restrict the existing position of a word by selecting a hypothesis that the fundamental frequency shape between supposed division points corresponds to any one of all reference shapes as a real hypothesis. CONSTITUTION: Since a pause is not generated in a level smaller than a word, the pause is detected at least and a conversation sentence is divided at the pause. Then the minimum position of fundamental frequency in the divided section is detected and the position is set up a divided candidate point. A division hypothesis supporting when each division point is a division point or when each division point is not a division point is set up and a hypothesis that the fundamented frequency shape between a divided point and a supposed point in each hypothesis corresponds to any one of all standard shapes is selected. When plural hypotheses are selected, the hypothesis having the highest reliability is selected as a real hypothesis. Thus, the division and shape of the conversation sentence is determined based upon the division point of the selected hypothesis and the obtained standard shape. |
