1. A fundamental frequency pattern generation apparatus comprising:

  • a first storage unit to store a plurality of representative vectors each corresponding to a prosodic control unit and having a section for changing the number of phonemes;

    a second storage unit to store a rule to select a representative vector corresponding to an input context;

    a selection unit configured to select the representative vector corresponding to the input context from the plurality of representative vectors by applying the rule to the input context and output the selected representative vector;

    a calculation unit configured to calculate an expansion/contraction ratio of the section of the selected representative 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 representative vector based on the expansion/contraction ratio to generate the fundamental frequency pattern.
