Patent number: 11594240Abstract: A headphone, headphone system, and speech enhancing method is provided to enhance speech pick-up from the user of a headphone and includes receiving a plurality of signals from a set of microphones and generating a primary signal by array processing the microphone signals to steer a beam toward the user's mouth. A noise reference signal is also derived from one or more microphones via a delay-and-sum technique, and a voice estimate signal is generated by filtering the primary signal to remove components that are correlated to the noise reference signal.Type: GrantFiled: July 16, 2020Date of Patent: February 28, 2023Assignee: Bose CorporationInventors: Alaganandan Ganeshkumar, Xiang-Ern Yeo, Mehmet Ergezer

Patent number: 10616676Abstract: The technology described in this document can be embodied in a method that includes receiving, at one or more processing devices of a headset that includes a sidetone generation circuit, an input signal representing ambient audio, and determining, by the one or more processing devices of the headset, that at least a portion of the input signal represents voice activity that satisfies a threshold condition. The method also includes, responsive to determining that the voice activity in the input signal satisfies the threshold condition, a control signal configured to cause the sidetone generation circuit to generate sidetone signals, and generating, by an acoustic transducer of the headset, an audio signal that represents, at least in part, the sidetone signals generated in accordance with the control signal.Type: GrantFiled: April 2, 2018Date of Patent: April 7, 2020Assignee: Bose CorporatonInventor: Xiang-Ern Yeo

Patent number: 10366708Abstract: A headphone system is provided that includes a left and right earpiece having a left and right microphone, respectively, to receive left and right acoustic signals and provide left and right signals for processing. The left and right signals are added to provide a principal signal, and the left and right signals are subtracted to provide a reference signal. A detection circuit compares the principal signal to the reference signal and selectively indicates whether a user is speaking.Type: GrantFiled: March 20, 2017Date of Patent: July 30, 2019Assignee: BOSE CORPORATIONInventors: Xiang-Ern Yeo, Mehmet Ergezer, Alaganandan Ganeshkumar
