    • There is provided a prosody generator that generates prosody information for implementing highly natural speech synthesis without unnecessarily collecting large quantities of learning data. A data dividing means 81 divides into subspaces the data space of a learning database as an assembly of learning data indicative of the feature quantities of speech waveforms. A density information extracting means 82 extracts density information indicative of the density state in terms of information quantity of the learning data in each of the subspaces divided by the data dividing means 81. A prosody information generating method selecting means 83 selects either a first method or a second method as a prosody information generating method based on the density information, the first method involving generating the prosody information using a statistical technique, the second method involving generating the prosody information using rules based on heuristics.

    • State duration creation means creates a state duration indicating a duration of each state in a hidden Markov model, based on linguistic information and a model parameter of prosody information. Duration correction degree computing means derives a speech feature from the linguistic information, and computes a duration correction degree which is an index indicating a degree of correcting the state duration, based on the derived speech feature. State duration correction means corrects the state duration based on a phonological duration correction parameter and the duration correction degree, the phonological duration correction parameter indicating a correction ratio of correcting a phonological duration.
