<P>PROBLEM TO BE SOLVED: To provide a method capable of measuring intonation variations underlying a speech under natural conditions. <P>SOLUTION: The method of measuring intonation variations includes a step 80 of preparing a prescribed set of citation values 56 of fundamental frequency (F0) targets for each of lexical tones obtained from isolated syllables 50 of a loudspeaker. The set of citation values of F0 targets characterizes a corresponding lexical tone. The method further includes a step 82 of extracting F0 target values for each syllable in sample speech data 52 of the loudspeaker and a step of calculating a prescribed first parameter 58 that measures the change from a citation value of a lexical tone of a syllable to an F0 target value, for each of the F0 target values of each syllable in the sample speech data 52. <P>COPYRIGHT: (C)2007,JPO&INPIT |
