1. A prosodic control rule generation method including:
- dividing an input text into language units;
estimating a punctuation mark incidence at a boundary between the language units, the punctuation mark incidence indicating a degree that a punctuation mark occurs at the boundary, based on attribute information items of a plurality of language units adjacent to the boundary; and
generating a prosodic control rule for speech synthesis including a condition for the punctuation mark incidence based on a plurality of learning data items each concerning prosody and including the punctuation mark incidence.

Abstract
A prosodic control rule generation method includes dividing an input text into language units, estimating a punctuation mark incidence at a boundary between language units in the input text, the punctuation mark incidence indicating a degree that a punctuation mark occurs at the boundary, based on attribute information items of a plurality of language units adjacent to the boundary, and generating a prosodic control rule for speech synthesis including a condition for the punctuation mark incidence based on a plurality of learning data items each concerning prosody and including the punctuation mark incidence.
