Abstract
Official abstract text for this publication.
An utterance state detection device includes an user voice stream data input unit that gets user voice stream data of an user, a frequency element extraction unit that extracts high frequency elements by frequency-analyzing the user voice stream data, a fluctuation degree calculation unit that calculates a fluctuation degree of the high frequency elements thus extracted every unit time, a statistic calculation unit that calculates a statistic every certain interval based on a plurality of the fluctuation degrees in a certain period of time, and an utterance state detection unit that detects an utterance state of a specified user based on the statistic obtained from user voice stream data of the specified user.
First claim
Opening claim text (preview).
What is claimed is: 1. An utterance emotional state detection device, comprising: a memory that stores a reply model including statistically processed information relating to a reply of a user in a normal state; and a processor coupled to the memory, wherein the processor executes a process comprising: acquiring user voice stream data of a specified user; extracting high frequency elements from the user voice stream data by frequency-analyzing; first calculating a fluctuat…
