Patent number: 10784989Abstract: A system includes a transmitter configured to transmit an original packet. The system also includes a receiver comprising a processing device. The processing device is configured to receive a corrupted Bluetooth® packet of the original packet and at least one retransmitted packet of the original packet. The processing device is also configured to generate an accumulated packet based on the corrupted packet and the at least one retransmitted packet, and generate a decision packet for the original packet based on the accumulated packet. The processing device is further configured to verify the decision packet to determine whether the decision packet is correct.Type: GrantFiled: September 14, 2018Date of Patent: September 22, 2020Assignee: Cypress Semiconductor CorporationInventor: Robert Zopf

Patent number: 10587954Abstract: The present disclosure is directed to systems, apparatuses, and methods for wirelessly delivering multi-channel audio over a packet based network with tight synchronization, high fidelity, and/or low delay as described above. The systems can include a source device that provides multi-channel audio to a distributor device, which wirelessly distributes the multi-channel audio over the packet based network to audio rendering devices, referred to as “sink” devices. The distributor device and the sink devices each include a playback clock that is used to read audio samples of the multi-channel audio from a local memory and drive a digital-to-analog converter (DAC) coupled to a speaker to render the audio samples.Type: GrantFiled: June 19, 2019Date of Patent: March 10, 2020Assignee: Avago Technologies International Sales Pte.

Patent number: 10468020Abstract: An example apparatus provides an input signal based on sound waves received by one or more microphones. The input signal includes a voice command component and one or more interference components. The apparatus receives audio data over one or more computer networks and the audio data corresponds to the one or more interference components. The apparatus uses the audio data to remove a portion of the one or more interference components from the input signal to generate an output signal, and provides the output signal, as an estimate of the voice command component, for speech recognition.Type: GrantFiled: September 26, 2017Date of Patent: November 5, 2019Assignee: Cypress Semiconductor CorporationInventors: Ashutosh Pandey, Robert Zopf

Publication number: 20190279641Abstract: A phrase detection device includes a high latency pipeline to transmit a first portion of audio data from an audio data source to a processing unit, where the high latency pipeline includes a history buffer to store the first portion of the audio data, and a low latency pipeline to transmit a second portion of the audio data from the audio data source to the processing unit with a lower latency than the high latency pipeline. A sound onset detector coupled with the audio data source detects a sound onset event based on the audio data. A synchronization circuit coupled with the high latency pipeline and the low latency pipeline, in response to the sound onset event, synchronizes output to the processing unit of the first portion of the audio data stored in the history buffer and the second portion of the audio data via the low latency pipeline.Type: ApplicationFiled: June 5, 2018Publication date: September 12, 2019Applicant: Cypress Semiconductor CorporationInventors: Victor Simileysky, Robert Zopf

Publication number: 20080052068Abstract: A system and method for processing of audio and speech signals is disclosed, which provide compatibility over a range of communication devices operating at different sampling frequencies and/or bit rates. The analyzer of the system divides the input signal in different portions, at least one of which carries information sufficient to provide intelligible reconstruction of the input signal. The analyzer also encodes separate information about other portions of the signal in an embedded manner, so that a smooth transition can be achieved from low bit-rate to high bit-rate applications. Accordingly, communication devices operating at different sampling rates and/or bit-rates can extract corresponding information from the output bit stream of the analyzer. In the present invention embedded information generally relates to separate parameters of the input signal, or to additional resolution in the transmission of original signal parameters.Type: ApplicationFiled: August 10, 2007Publication date: February 28, 2008Inventors: Joseph Aguilar, David Campana, Juin-Hwey (Raymond) Chen, Robert Dunn, Robert McAulay, Xiaoquin Sun, Wei Wang, Craig Watkins, Robert Zopf

Publication number: 20060064301Abstract: A system and method are provided for processing audio and speech signals using a pitch and voicing dependent spectral estimation algorithm (voicing algorithm) to accurately represent voiced speech, unvoiced speech, and mixed speech in the presence of background noise, and background noise with a single model. The present invention also modifies the synthesis model based on an estimate of the current input signal to improve the perceptual quality of the speech and background noise under a variety of input conditions. The present invention also improves the voicing dependent spectral estimation algorithm robustness by introducing the use of a Multi-Layer Neural Network in the estimation process. The voicing dependent spectral estimation algorithm provides an accurate and robust estimate of the voicing probability under a variety of background noise conditions. This is essential to providing high quality intelligible speech in the presence of background noise.Type: ApplicationFiled: October 28, 2005Publication date: March 23, 2006Inventors: Joseph Aguilar, Juin-Hwey Chen, Wei Wang, Robert Zopf
