摘要:
A fundamental frequency pattern generation apparatus includes a first storage including representative vectors each corresponding to a prosodic control unit and having a section for changing the number of phonemes, a second storage unit including a rule to select a vector corresponding to an input context, a selection unit configured to select a vector from the representative vectors by applying the rule to the context and output the selected vector, a calculation unit configured to calculate an expansion/contraction ratio of the section of the selected vector in a time-axis direction based on a designated value for a specific feature amount related to a length of a fundamental frequency pattern to be generated, the designated value of the feature amount being required of the fundamental frequency pattern to be generated, and an expansion/contraction unit configured to expand/contract the selected vector based on the expansion/contraction ratio to generate the fundamental frequency pattern.
