| Abstract(in English) | This paper describes a method of voice characteristic similarity focusing on difference of voice characteristics conveyed by instantaneous spectrum information. Speech data of sentences or words include various factors affecting voice characteristics, such as prosody and time-varying properties. Isolated Japanese vowels (/a/ and /i/) which are uttered with a fixed F0 frequency are used for a listening test and training a model of automatic estimation of the voice characteristic similarity. In the listening test, subjects were asked to judge identity for each pair of speakers. It is confirmed that it is possible to measure similarity of speakers by listening isolated vowels. Weighted Euclidean distance of acoustic features is a measure of automatically estimated similarity of voice characteristic MFCC parameters are used as acoustic features. The performance of estimation is increased by using high order MFCC up to 16. Weighted Euclidean distance shows higher correlation with listening test results than simple Euclidean distance. |
