Abstract:
A sound source generation device characterized in that the device comprises:calculating component for sound source generating parameters for outputting fundamental frequency at least as sound source generating parameters, upon receiving the command concerning prosody and according to the said command; andsound source generating component for generating sound source upon receiving sound source generating parameters from calculating component for sound source generating parameters and according to the said sound source generating parameters;wherein the generation of fundamental frequency is represented in the model with two forces:a force .tau.1 that causes the thyroid cartilage to rotate, by virtue of contraction of the cricothyroid muscle, toward the vocal folds stretch and a force .tau.2 that causes the cricoid cartilage to rotate toward the vocal folds contraction; andboth the accent command corresponding to the said force .tau.1 and the descent command corresponding to the said force .tau.2 are given for calculating fundamental frequency; andcalculating component for sound source generating parameters calculates sound source generating parameters according to the accent command and the descent command.
