20150341722 | METHODS AND DEVICES FOR REVERBERATION SUPPRESSION - In one embodiment, a process for suppressing reverberation begins with a device of a user obtaining a reverberant speech signal from a voice of the user. The device determines a first estimated reverberation component of the reverberant speech signal. The device generates a first de-reverberated output signal with a first reverberation suppression based on the reverberant speech signal and the first estimated reverberation component. Then, the device generates a second improved reverberation component using the first de-reverberated output signal. The device generates a second de-reverberated output signal with a second reverberation suppression based on the reverberant speech signal and the second improved reverberation component. | 2015-11-26 |
20150341723 | MULTITASK LEARNING METHOD FOR BROADBAND SOURCE-LOCATION MAPPING OF ACOUSTIC SOURCES - A method involves acoustic source localization by capitalizing on the sparse nature of a source location map (SLM). Sparsity arises naturally since one seeks the location of K sources in a grid of G tentative locations where G>>K. The source localization problem is cast as a regularized LS regression problem with a sparsity constraint whose solution yields the SLM. An iterative solver based on block coordinate descent (BCD) is used. BCD leads to scalar closed-form updates rendering the method's computational complexity per iteration linear with respect to the grid size. The disclosed method enables high resolution location estimation with fewer array measurements than classical matched field processing methods. | 2015-11-26 |
20150341724 | NEW METHOD OF WIRELESS TRANSMISSION OF DIGITAL AUDIO - A method of wireless communication of data sets includes: transmitting a first data set of a first data category from a transmitter for reception by a receiver; and re-transmitting the first data set at a time after the first data set is transmitted if there is an absence of an acknowledgement of receipt from the receiver, or transmitting a second data set of a second data category that is different from the first data category from the transmitter to the receiver at the time if there is a presence of the acknowledgement of receipt from the receiver. | 2015-11-26 |
20150341725 | ELECTROACOUSTIC TRANSDUCER - An electroacoustic transducer includes a diaphragm including: a wing-pair portion; and a cone portion. The wing-pair portion includes a pair of convex surfaces having respectively convex surfaces of a pair of longitudinal split tubular members. A valley is formed between one side portions of the pair of convex surfaces. The cone portion surrounds an outer peripheral portion of the wing-pair portion and extends in a conical shape. The electroacoustic transducer further includes: a converter configured to convert between a vibration of the diaphragm in a depth direction of the valley and an electric signal corresponding to the vibration; and a supporter supporting an outer peripheral portion of the cone portion to allow the diaphragm to vibrate in a direction of the vibration. | 2015-11-26 |
