Title: Speech response device
Inventor: HARA YOSHIYUKI
IPC: G10L13/02
Filed: 1989-05-12
Abstract: PURPOSE:To synthesize a highly natural synthetic voice by gathering pieces of frequency information on words which are successful in matching with an accent dictionary and deleting words which has low frequencies. CONSTITUTION:A host computer 3 supplies character string information (word) to a voice rule synthesis part 7 and the accent dictionary 8 is referenced for rule synthesis. In this case, the appearance frequency of a word which is successful in matching is increased. The threshold value for the deletion of words which are low in frequency is set and inputted and the computer 2 deletes the words which are smaller than the threshold value. Important words are excluded from objects of deletion even when they are low in frequency. Thus, pieces of accent information on only the important words and words which are high in use frequency are left in the dictionary 8, so a highly natural voice can be synthesized.
