Abstract: An acoustic noise suppressing apparatus outputs a first suppression audio signal in which the acoustic noise is suppressed by subtracting a first pseudo noise signal from the picked up audio signal, the first pseudo noise signal being generated based on a first delay signal and a first filter updated by a first algorithm which is valid when a plurality of talkers are talking, and outputs a second suppression audio signal in which the acoustic noise is suppressed by subtracting a second pseudo noise signal from the picked up audio signal, the second pseudo noise signal being generated based on a second delay signal and a second filter updated by a second algorithm which is valid when one talker is talking. The apparatus outputs a suppressed one of the first suppressed audio signal or the second suppressed audio signal.

Abstract: An authentication device includes an acquisition unit configured to acquire a voice signal of a speaker; a detection unit configured to detect a first utterance period during which the speaker is speaking; and an authentication unit configured to authenticate the speaker based on a comparison between a voice signal of the first utterance period and a database. The detection unit detects a second utterance period different from the first utterance period when the authentication unit determines that the speaker authentication is impossible, and the authentication unit authenticates the speaker based on a comparison between the voice signal of the first utterance period and a voice signal of the second utterance period, and the database.
