SPEAKER-ADAPTIVE APPARATUS FOR LEARNING SHIFT AMOUNT OF FUNDAMENTAL FREQUENCY, APPARATUS FOR GENERATING FUNDAMENTAL FREQUENCY, METHOD FOR LEARNING SHIFT AMOUNT, METHOD FOR GENERATING FUNDAMENTAL FREQUENCY, AND PROGRAM FOR LEARNING SHIFT AMOUNT

摘要

Disclosed is such technology capable of precisely reproducing the feature of a basic frequency of the voice of a target speaker on the basis of only a small amount of learned data. A learning device which learns an amount of the movement of the target F pattern of the target speaker with respect to a fundamental source F0 pattern associates a source F0 pattern corresponding to a learning text with a target F0 pattern corresponding to the same learning text so that crests correspond to crests and troughs correspond to troughs, obtains with respect to each point on the target F0 pattern the amounts of movement in a time-axis direction and a frequency-axis direction from a corresponding point on the source F0 pattern by referring to the result of the association, and .....
