INFORMATION PROCESSING DEVICE AND METHOD AND PROGRAM
First Claim
1. An information processing device comprising:
- output means for performing notification to a user by outputting ringing sound;
sound pickup means for picking up surrounding sound as ambient sound;
adaptive filtering process means for performing an adaptive filtering process using the picked-up ambient sound and the ringing sound output from the output means, to thereby extract, from the ambient sound, estimated environmental sound from which the ringing sound picked up by the sound pickup means has been removed; and
control means for controlling, on the basis of the feature quantity of a predetermined feature extracted from the estimated environmental sound, the adjustment of at least one of the sound volume and the sound quality of the ringing sound.

Abstract
An information processing device includes: an output device configured to perform notification to a user by outputting ringing sound; a sound pickup device configured to pick up surrounding sound as ambient sound; an adaptive filtering process device configured to perform an adaptive filtering process using the picked-up ambient sound and the ringing sound output from the output device, to thereby extract, from the ambient sound, estimated environmental sound from which the ringing sound picked up by the sound pickup device has been removed; and a control device configured to control, on the basis of the feature quantity of a predetermined feature extracted from the estimated environmental sound, the adjustment of at least one of the sound volume and the sound quality of the ringing sound.

10. An information processing method performed by an information processing device including
output means for performing notification to a user by outputting ringing sound, sound pickup means for picking up surrounding sound as ambient sound, adaptive filtering process means for performing an adaptive filtering process using the picked-up ambient sound and the ringing sound output from the output means, to thereby extract, from the ambient sound, estimated environmental sound from which the ringing sound picked up by the sound pickup means has been removed, and control means for controlling, on the basis of the feature quantity of a predetermined feature extracted from the estimated environmental sound, the adjustment of at least one of the sound volume and the sound quality of the ringing sound, wherein the information processing method comprises the steps of: -
causing the output means to output the ringing sound; causing the sound pickup means to pick up the ambient sound; causing the adaptive filtering process means to perform the adaptive filtering process and extract the estimated environmental sound; and causing the control means to control, on the basis of the feature quantity of the estimated environmental sound, the adjustment of the sound volume or the sound quality of the ringing sound.

11. A program for causing a computer to perform processing comprising the steps of:
-
causing output means to perform notification to a user by outputting ringing sound; causing sound pickup means to pick up surrounding sound as ambient sound; performing an adaptive filtering process using the picked-up ambient sound and the ringing sound output from the output means, to thereby extract, from the ambient sound, estimated environmental sound from which the ringing sound picked up by the sound pickup means has been removed; and controlling, on the basis of the feature quantity of a predetermined feature extracted from the estimated environmental sound, the adjustment of at least one of the sound volume and the sound quality of the ringing sound.
