Publication number: 20220277744Abstract: A vehicle includes an interface device, an in-vehicle control unit, a functional unit, and a processing circuitry. The interface device receives a spoken command to identify an in-cabin vehicle zone of two or more in-cabin vehicle zones of the vehicle, and receives background audio data concurrently with a portion of the spoken command. The in-cabin vehicle control unit separates the background audio data from the spoken command, and selects which in-cabin vehicle zone of the two or more in-cabin vehicle zones is identified by the spoken command. The functional unit controls a function within the vehicle. The processing circuitry stores, to a command buffer, data processed from the received spoken command, and controls, based on the data processed from the received spoken command, the functional unit using audio input received from the selected in-cabin vehicle zone.Type: ApplicationFiled: May 18, 2022Publication date: September 1, 2022Inventors: Asif Iqbal Mohammad, Sreekanth Narayanaswamy, Rishabh Tyagi, Erik Visser

Patent number: 9936290Abstract: A method for multi-channel echo cancellation and noise suppression is described. One of multiple echo estimates is selected for non-linear echo cancellation. Echo notch masking is performed on a noise-suppressed signal based on an echo direction of arrival (DOA) to produce an echo-suppressed signal. Non-linear echo cancellation is performed on the echo-suppressed signal based, at least in part, on the selected echo estimate.Type: GrantFiled: January 15, 2014Date of Patent: April 3, 2018Assignee: QUALCOMM IncorporatedInventors: Asif Iqbal Mohammad, Lae-Hoon Kim, Ian Ernan Liu, Erik Visser

Patent number: 9769587Abstract: A multi-channel sound (MCS) system features intelligent calibration (e.g., of acoustic echo cancellation (AEC)) for use in dynamic acoustic environments. A sensor subsystem is utilized to detect and identify changes in the acoustic environment and determine a “scene” corresponding to the resulting acoustic characteristics for that environment. This detected scene is compared to predetermined scenes corresponding to the acoustic environment. Each predetermined scene has a corresponding pre-tuned filter configuration for optimal AEC performance. Based on the results of the comparison, the pre-tuned filter configuration corresponding to the predetermined scene that most closely matches the detected scene is utilized by the AEC subsystem of the multi-channel sound system.Type: GrantFiled: April 17, 2015Date of Patent: September 19, 2017Assignee: QUALCOMM IncorporatedInventors: Andre Gustavo Schevciw, Babak Forutanpour, Asif Iqbal Mohammad, Lae-Hoon Kim

Patent number: 9672805Abstract: A crosstalk cancelation technique reduces feedback in a shared acoustic space by canceling out some or all parts of sound signals that would otherwise be produced by a loudspeaker to only be captured by a microphone that, recursively, would cause these sounds signals to be reproduced again on the loudspeaker as feedback. Crosstalk cancelation can be used in a multichannel acoustic system (MAS) comprising an arrangement of microphones, loudspeakers, and a processor to together enhance conversational speech between in a shared acoustic space. To achieve crosstalk cancelation, a processor analyzes the inputs of each microphone, compares it to the output of far loudspeaker(s) relative to each such microphone, and cancels out any portion of a sound signal received by the microphone that matches signals that were just produced by the far loudspeaker(s) and sending only the remaining sound signal (if any) to such far loudspeakers.Type: GrantFiled: July 24, 2015Date of Patent: June 6, 2017Assignee: QUALCOMM IncorporatedInventors: Lae-Hoon Kim, Asif Iqbal Mohammad, Erik Visser

Patent number: 9275625Abstract: Apparatus and methods for audio noise attenuation are disclosed. An audio signal analyzer can determine whether an input audio signal received from a microphone device includes a noise signal having identifiable content. If there is a noise signal having identifiable content, a content source is accessed to obtain a copy of the noise signal. An audio canceller can generate a processed audio signal, having an attenuated noise signal, based on comparing the copy of the noise signal to the input audio signal. Additionally or alternatively, data may be communicated on a communication channel to a separate media device to receive at least a portion of the copy of the noise signal from the separate media device, or to receive content-identification data corresponding to the content source.Type: GrantFiled: March 6, 2013Date of Patent: March 1, 2016Assignee: QUALCOMM IncorporatedInventors: Lae-Hoon Kim, Asif Iqbal Mohammad, Erik Visser, Jongwon Shin
