摘要
PROBLEM TO BE SOLVED: To provide the hearing aid with the speaking speed converting function which can convert a speech signal to a proper speaking speed and output it whatever voicing speed (speaking speed) the speech signal has. ;SOLUTION: When the speech signal is inputted, the length Lpth of the vowel of the syllable at the head is measured. For example, when 'ohayou'(Good morning in English) is inputted, 'o' is inputted first, so when this 'o' is detected, its length is measured. On the basis of the length of the 'o', the speaking speed of the input speech signal is detected and a conversion rate for the speaking speed is calculated from the detected length and a target speaking speed value. Then 'hayou' inputted following the 'o' is converted with this conversion rate to perform speaking speed conversion corresponding to the speaking speed of the input speech signal almost in real time, so that the speech signal can be outputted at the target speaking speed all the times.;COPYRIGHT: (C)1998,JPO
