Abstract: A presence and absence prediction method includes: acquiring electric power data of a predetermined building at a first point in time; acquiring learning data obtained by learning, for each predetermined time period, a correspondence relationship between electric power data of the building at a point in time preceding the first point in time and information indicating whether the person was actually present in the building; predicting, on the basis of the electric power data of the building at the first point in time and the learning data, whether the person is present in the building; and generating presence and absence information that indicates a result of the prediction and outputting the presence and absence information to a predetermined terminal.

Abstract: A speaker identification system (100) includes a microphone (2) which acquires speech information of a speaker; a sex/age range information acquisition unit (7) which acquires age range information relating to a range of the age of the speaker, based on the speech information; a specific age information acquisition unit (8) which acquires specific age information relating to the specific age of the speaker, based on the speech information; a date and time information acquisition unit (9) which acquires date and time information representing the date and time when the speech information has been acquired; and a speaker database (4) which accumulates the specific age information, and the date and time information in association with each other.

Abstract: The hearing aid makes conversation sound easier to hear. The hearing aid device (100) comprises a first audio controller (40) that receives a center signal (C), a left-front signal (L), a right-front signal (R), a left-rear signal (SL), and a right-rear signal (SR), and second audio controller (20) that receives the output signal from the first audio controller (40). The first audio controller (40) has a sound image localization processor (42) that locates a sound image in a specific direction with respect to the left-front signal (L), the right-front signal (R), the left-rear signal (SL), and the right-rear signal (SR).

Abstract: A hearing aid for improving diminished hearing caused by reduced temporal resolution includes: a speech input unit which receives a speech signal from outside; a speech analysis unit which detects a sound segment and a segment acoustically regarded as soundless from the speech signal received by the speech input unit and detects a consonant segment and a vowel segment within the detected sound segment; and a signal processing unit which temporally increments the consonant segment detected by the speech analysis unit and temporally decrements at least one of the vowel segment and the segment acoustically regarded as soundless detected by the speech analysis unit.

Abstract: A hearing aid (100) fits in an ear of a user and amplifies a sound and outputs the amplified sound.

Abstract: A hearing aid for improving diminished hearing caused by reduced temporal resolution includes: a speech input unit (201) which receives a speech signal from outside; a speech analysis unit (202) which detects a sound segment and a segment acoustically regarded as soundless from the speech signal received by the speech input unit and detects a consonant segment and a vowel segment within the detected sound segment; and a signal processing unit (204) which temporally increments the consonant segment detected by the speech analysis unit (204) and temporally decrements at least one of the vowel segment and the segment acoustically regarded as soundless detected by the speech analysis unit (204).

Abstract: A sound image localization device (10) comprising: band division means (11) for dividing an inputted acoustic signal to a high-band acoustic signal and a low-band acoustic signal; a first filter (12) and a second filter (13) for localizing the high-band acoustic signal; low-band localization means (16) having a third filter (14) and a fourth filter (15) for localizing the low-band acoustic signal; a first adder (17) for adding the output signals of the first filter (12) and the third filter (14), and a second adder (18) for adding the output signals of the second filter (13) and the fourth filter (15). The sound image localization device (10) having such a configuration mitigates the limit of the listening position as compared to the conventional one and enables localization of the sound image in any direction around a listener.
