Publication number: 20250078855Abstract: A signal filtering device includes: an information generation unit that generates feature information on related information on a target signal; an extraction unit that extracts mask information from a mixed signal including the target signal on the basis of the feature information; and a mask processing unit that estimates the target signal from the mixed signal using the mask information. The information generation unit may encode the related information into a multidimensional vector and generate a linear transformation result of the multidimensional vector as the feature information. The information generation unit may encode the related information into a first multidimensional vector, encode the mixed signal into a second multidimensional vector, derive a similarity in time series between the first multidimensional vector and the second multidimensional vector, and generate a result of a weighted sum of the similarity in time series and the mixed signal as the feature information.Type: ApplicationFiled: December 27, 2021Publication date: March 6, 2025Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Yasunori OISHI, Marc DELCROIX, Tsubasa OCHIAI, Shoko ARAKI, Daiki TAKEUCHI, Daisuke NIIZUMI, Akisato KIMURA, Kunio KASHINO, Noboru HARADA

Publication number: 20250069614Abstract: A signal filtering device includes: a separation unit that separates a predetermined number of possibility signals from a mixed signal as possibilities of a target signal; an encoding unit that encodes related information of the target signal into a first feature vector and encodes the predetermined number of possibility signals into the predetermined number of second feature vectors; and a selection unit that derives a similarity between the first feature vector and the second feature vector for each of the possibility signals, and selects a possibility signal of the possibility signals having the highest similarity as the target signal from the predetermined number of possibility signals. The selection unit may derive an inner product of the first feature vector and the second feature vector as the similarity. The predetermined number of possibility signals may be voice signals associated with the predetermined number of sound sources.Type: ApplicationFiled: December 27, 2021Publication date: February 27, 2025Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Yasunori OISHI, Marc DELCROIX, Tsubasa OCHIAI, Shoko ARAKI, Daiki TAKEUCHI, Daisuke NIIZUMI, Akisato KIMURA, Noboru HARADA, Kunio KASHINO

Patent number: 8036699Abstract: It is possible to surely protect the user's ear from a sudden large volume and enable the user to surely and clearly hear a sound as information to be alarmed. In case an incoming call signal is received when the user holds a mobile telephone (1) at the speaking position and listens to a message output from an audio output unit (8), a control unit (17) makes a vibrator (27) generate a vibration as an alarm to call user's attention. At the timing when the user has sufficiently separated the mobile telephone (1) from his/her ear, the control unit (17) makes the audio output unit (8) output a ringtone of large volume. Thus, it is possible to surely protect the user's ear from a sudden large volume. Even when a music composition to notify the receipt of incoming call signal is used as a ringtone, the user can surely and clearly hear the sound as information to be alarmed.Type: GrantFiled: March 1, 2006Date of Patent: October 11, 2011Assignee: NEC CorporationInventor: Daisuke Araki
