会話評価装置およびプログラム
Document Type and Number:
Japanese Patent JP6464703
Kind Code:
B2
Abstract:
Information related to voice of a question and information related to voice of a response to the question are received. On the basis of the received information, an analysis section (106) acquires a representative pitch of the question (e.g., a pitch of the end of the question), and a representative pitch of the response (e.g., an average pitch of the response). Further, on the basis of comparison between the representative pitch of the question and the representative pitch of the response, an evaluation section (110) evaluates the voice of the response to the question on the basis of how much a difference (interval) between the respective representative pitches of the question and the response is away from a predetermined reference value (e.g., a consonant interval of a fifth below). Further, a conversation interval detection section (109) is provided for detecting a conversation interval, i.e., a time interval from the end of the question to the start of the response. The evaluation section further evaluates the response to the question on the basis of the detected conversation interval. In this manner, a non-linguistic characteristic of the response to the question (whether an impression given by the response is good or bad) can be evaluated in an objective fashion.
