STATE DETECTOR, STATE DETECTION METHOD AND PROGRAM FOR STATE DETECTION

摘要

PROBLEM TO BE SOLVED: To provide a state detector for precisely detecting a state of a specific speaker while reducing the load.

SOLUTION: The state detector includes first model generating means that generates, in the state detector, a first specific speaker model in which voice characteristics of a specific speaker under a non-suppression state are modeled for precisely detecting a state of the specific speaker by utilizing information included in the voice; second model generating means that generates a second specific speaker model in which voice characteristics of the specific speaker under a suppression state are modeled by reflecting a displacement to a second non-specific speaker model with respect to a first non-specific speaker model to the first specific speaker model based on the corresponding relationship information; likelihood calculation means that calculates a first likelihood representing the likelihood of the first specific speaker model with respect to input voice characteristics and a second likelihood representing the likelihood of the second specific speaker model with respect to an input voice; and state determination means that determines the state of the speaker of the input voice based on the first likelihood and the second likelihood.
