In one embodiment, a system for canceling acoustic echoes comprises one or more microphones configured to pick up sound generated by a sound source and transferred from the sound source to the one or more microphones via one or more unknown transfer paths having one or more unknown transfer functions, and to provide one or more electrical microphone signals therefrom, one or more adaptive filters for approximating the one or more unknown transfer functions with one or more estimated transfer functions and filtering one or more electrical signals representative of the sound generated by the sound source with the one or more estimated transfer functions to provide one or more estimated signals therefrom, and a microphone calibration block configured to individually attenuate or amplify the one or more electrical microphone signals dependent on the one or more estimated transfer functions. | 2020-05-14 |
20200152220 | ECHO CANCELLATION FOR KEYWORD SPOTTING - Techniques of performing linear acoustic echo cancellation performing a phase correction operation on the estimate of the echo signal based on a clock drift between a capture of an input microphone signal and a playout of a loudspeaker signal. Along these lines, the existence of the clock drift, i.e., a small difference in the sampling rates of the input microphone signal and the loudspeaker signal, can cause processing circuitry in a device configured to perform LAEC operations to generate a filter based on the magnitudes of the short-term Fourier transforms (STFTs) of the input microphone signal and the loudspeaker signal. Such a filter is real-valued and results in a positive estimate of the acoustic echo signal included in the input microphone signal. The phase of this estimate may then be aligned with the phase of the input microphone signal. | 2020-05-14 |
20200152221 | SOUND COLLECTION DEVICE, MOVING BODY, AND SOUND COLLECTION METHOD - A sound collection device includes a sensor, a database, a microphone, and an electronic controller. The sensor detects a state of at least one of the sound collection device or a device equipped with the sound collection device, or both. The database is a database of noise sounds. The electronic controller includes a signal processing unit configured to read at least one noise sound from the database based on a detection value of the sensor and carry out a noise reduction process to reduce noise from a sound signal acquired by the microphone based on the at least one noise sound read from the database. | 2020-05-14 |
20200152222 | PROCESSING OF SOUND DATA FOR SEPARATING SOUND SOURCES IN A MULTICHANNEL SIGNAL - A method for processing sound data for separating N sound sources of a multichannel sound signal sensed in a real medium. The method includes: separating sources to the sensed multichannel signal and obtaining a separation matrix and a set of M sound components, with M≥N; calculating a set of bi-variate first descriptors representative of statistical relations between the components of the pairs of the set obtained of M components, calculating a set of uni-variate second descriptors representative of characteristics of encoding of the components of the set obtained of M components; and classifying the components of the set of M components, according to two classes of components, a first class of N direct components corresponding to the N direct sound sources and a second class of M−N reverberated components, by calculating probability of membership in one of the two classes, dependent on the sets of first and second descriptors. | 2020-05-14 |
20200152223 | SOMATIC, AUDITORY AND COCHLEAR COMMUNICATION SYSTEM AND METHOD - Methods and devices to deliver a tactile speech analog to a person's skin providing a silent, invisible, hands-free, eyes-free, and ears-free way to receive and directly comprehend electronic communications. Embodiments include an alternative to hearing aids that will enable people with hearing loss to better understand speech. A device, worn like watch or bracelet, supplements a person's remaining hearing to help identify and disambiguate those sounds he or she can not hear properly. Embodiments for hearing aids and hearing prosthetics are also described. | 2020-05-14 |
20200152224 | Using Images and Residues of Reference Signals to Deflate Data Signals - A system processes data signals consisting of sums of independent signal terms, zero or more of which signal terms may already have been identified, in order to generate one or more additional terms. Deflated versions of the data signals are created by subtracting from the data signals any previously identified signal terms. Additional independent signal terms are computed using a set of reference signals organized into mutually independent partioning support sets. The images of each support set are computed on the data signals. Computed images on a data signal that are non-zero are identified as additional independent signal terms of that data signal. | 2020-05-14 |
