Abstract
A sound state estimating unit detects surrounding sound at a timing at which a notification to a destination user occurs. A user state estimating unit detects a position of the destination user and positions of users other than the destination user at the timing at which the notification occurs. An output control unit controls output of the notification to the destination user at a timing at which it is determined that the surrounding sound detected by the sound state estimating unit is masking possible sound which can be used for masking in a case where the position of the destination user detected by the user state estimating unit is within a predetermined area.
Claims14
A signal processing apparatus comprising:
- a sound detecting unit configured to detect surrounding sound at a timing at which a notification to a destination user occurs;
- a position detecting unit configured to detect a position of the destination user and positions of users other than the destination user at the timing at which the notification occurs;
- and
- an output control unit configured to control output of the notification to the destination user at a timing at which it is determined that the surrounding sound detected by the sound detecting unit is masking possible sound which can be used for masking in a case where the position of the destination user detected by the position detecting unit is within a predetermined area.
A signal processing method executed by a signal processing apparatus, the method comprising:
- detecting surrounding sound in a case where there is a notification to a destination user;
- detecting a position of the destination user and positions of users other than the destination user;
- and
- controlling output of the notification to the destination user at a timing at which it is determined that the surrounding sound detected by the sound detecting unit is masking possible sound which can be used for masking in a case where the position of the destination user detected by the position detecting unit is within a predetermined area.
A program for causing a computer to function as:
- a sound detecting unit configured to detect surrounding sound at a timing at which a notification to a destination user occurs;
- a position detecting unit configured to detect a position of the destination user and positions of users other than the destination user at the timing at which the notification occurs;
- and
- an output control unit configured to control output of the notification to the destination user at a timing at which it is determined that the surrounding sound detected by the sound detecting unit is masking possible sound which can be used for masking in a case where the position of the destination user detected by the position detecting unit is within a predetermined area.
