    Abstract: A speech processing device includes a distance acquisition unit configured to acquire a distance between a sound collection unit configured to record speech from a sound source and the sound source, a reverberation characteristic estimation unit configured to estimate a reverberation characteristic based on the distance acquired by the distance acquisition unit, a correction data generation unit configured to generate correction data indicating a contribution of a reverberation component from the reverberation characteristic estimated by the reverberation characteristic estimation unit; and a dereverberation unit configured to remove the reverberation component from the speech by correcting the amplitude of the speech based on the correction data.

    Abstract: A speech processing device includes a speech recognition unit configured to sequentially recognize recognition segments from an input speech, a reverberation influence storage unit configured to store a degree of reverberation influence indicating an influence of a reverberation based on a preceding speech to a subsequent speech subsequent to the preceding speech and a recognition segment group including a plurality of recognition segments in correlation with each other, a reverberation influence selection unit configured to select the degree of reverberation influence corresponding to the recognition segment group which includes the plurality of recognition segments recognized by the speech recognition unit from the reverberation influence storage unit, and a reverberation reduction unit configured to remove a reverberation component weighted with the degree of reverberation influence from the speech from which at least a part of recognition segments of the recognition segment group is recognized.

    Abstract: A reception system includes: a visitor recognition unit that recognizes a visitor; a receiving person recognition unit that recognizes a receiving person that corresponds to the visitor; a receiving person contact information storage unit that stores contact information of the receiving person; a notification unit that notifies the receiving person of a visit of the visitor at the contact information of the receiving person stored by the receiving person contact information storage unit; and a receiving person selection unit that selects a substitute receiving person associated with the receiving person in a case where the receiving person is absent when the notification unit notifies the receiving person at the contact information of the receiving person, wherein the notification unit notifies the substitute receiving person selected by the receiving person selection unit when the receiving person is absent.
