Abstract: To ensure optimization of a voice output timing. A voice synthesis apparatus that performs voice synthesis based on a statistical acoustic model includes a processor that executes a program and a storage device that stores the program. The voice synthesis apparatus performs a selection process and a synthesis process. The selection process selects a synthesis method applied to an input voice among a plurality of synthesis methods in combination of sizes of the statistical acoustic models with voice synthesis processes based on the input voice. The synthesis process synthesizes the input voice by the synthesis method selected in the selection process.

Abstract: A robot dialogue system includes a robot with a processor and memory that communicates with a user and a dialogue server with a processor and memory that controls the robot. From a user inquiry the robot calculates speech content and a confidence factor and transmits the speech content and the confidence factor to the dialogue server, which stores an action and a confidence factor corresponding to the speech content in state information. The dialogue server selects a new action having the highest confidence factor in the state information, calculates a cost incurred when the new action is implemented from the robot's present state, selects a combination of candidates excluding the highest confidence factor action as a new candidate of action, calculates a cost incurred when the new candidate of action is implemented, and selects an action or a candidate of action with the lowest cost as a new action.
