DEVICE FOR LEARNING AMOUNT OF MOVEMENT OF BASIC FREQUENCY FOR ADAPTING TO SPEAKER, BASIC FREQUENCY GENERATION DEVICE, AMOUNT OF MOVEMENT LEARNING METHOD, BASIC FREQUENCY GENERATION METHOD, AND AMOUNT OF MOVEMENT LEARNING PROGRAM

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 learns a decision tree with language information being an analytic result of the learning text as an input feature amount and the calculated amounts of movement as output feature amounts.
