  • Patent number: 11006201
    Abstract: Disclosed is a signal processor for headphone off-ear detection. The signal processor includes an audio output to transmit an audio signal toward a headphone speaker in a headphone cup. The signal processor also includes a feedback (FB) microphone input to receive a FB signal from a FB microphone in the headphone cup. The signal processor also includes an off-ear detection (OED) signal processor to determine an audio frequency response of the FB signal over an OED frame as a received frequency response. The OED processor also determines an audio frequency response of the audio signal times an off-ear transfer function between the headphone speaker and the FB microphone as an ideal off-ear response. A difference metric si generated comparing the received frequency response to the ideal off-ear frequency response. The difference metric is employed to detect when the headphone cup is disengaged from an ear.

  • Patent number: 10547930
    Abstract: A head-mounted wearable device (HMWD) may incorporate bone conduction speakers (BCS) to generate audio output that is perceptible to a wearer. Due to the mechanical connection between the BCS and the rest of the device, when the output amplitude of the BCSs is too great, the air-conducted audio “leaks” and may be heard by other people. This leakage may result in eavesdropping by, or generate a nuisance to, those other people. The noise level in the environment around the HMWD is determined and used to dynamically adjust the amplitude of the audio output generated by the BCS. This adjustment improves the comfort and intelligibility of the audio output to the wearer while minimizing audio leakage to the surrounding environment.

The application then constructs an identity model and excites the identity model with an identical input under identical conditions, to generate a set of spreading function filters. The application computes the inverse of the spreading function filters and convolves the inverse spreading function filters with the Farina harmonic response filters to generate a set of spreading corrected filters. Finally, the application constructs the unmixing Chebyshev matrix and convolves the spreading correction filters with the unmixing Chebyshev matrix to remove the spreading and generate harmonically pure and phase-corrected filters.

  • Patent number: 10304448
    Abstract: Environmental conditions, along with other information, are used to adjust a response of a conversational dialog system. The environmental conditions may be used at different times within the conversational dialog system. For example, the environmental conditions can be used to adjust the dialog manager's output (e.g., the machine action). The dialog state information that is used by the dialog manager includes environmental conditions for the current turn in the dialog as well as environmental conditions for one or more past turns in the dialog. The environmental conditions can also be used after receiving the machine action to adjust the response that is provided to the user. For example, the environmental conditions may affect the machine action that is determined as well as how the action is provided to the user. The dialog manager and the response generation components in the conversational dialog system each use the available environmental conditions.

  • Patent number: 10224016
    Abstract: A noise cancelling headset includes an earpiece, the earpiece including a feedback microphone, a feed-forward microphone, and an output driver. A first feedback filter receives an input from at least the first feedback microphone and produces a first filtered feedback signal. A first feed-forward filter receives an input from at least the first feed-forward microphone and produces a first filtered feed-forward signal. A first summer combines the first filtered feedback signal and the first filtered feed-forward signal and produces a first output signal. An output interface provides the first output signal as an output from the headset.

  • Patent number: 10141903
    Abstract: An audio system for a vehicle is described. The audio system includes an audio control computer device and an exterior audio assembly. The audio control computer device is in communication with a memory device. The audio control computer device is configured to store, in the memory device, at least one limited volume level and a corresponding speed range, receive a speed-related parameter indicative of an actual speed of the vehicle from a vehicle control system, determine if the actual speed of the vehicle is within the stored speed range based on the speed-related parameter, and permit operation of the exterior audio assembly at the at least one limited volume level when the actual speed of the vehicle is within the speed range.

  • Patent number: 10104472
    Abstract: An acoustic capture device includes an acoustic transducer, an acoustic detector, an analog-to-digital converter, and a processing element. The acoustic transducer captures an acoustic wave to generate an analog signal. The acoustic detector detects, according to the analog signal, a specific event to generate a trigger signal. The analog-to-digital converter converts the analog signal to generate a digital signal. The processing element receives the trigger signal to execute a control process. The control process includes: analyzing the digital signal to determine ambient information; determining a first set of parameters of the acoustic detector according to the ambient information; performing a control information protocol to adjust the acoustic detector according to the first set of parameters; and performing, according to the ambient information, an enhancement processing on the digital signal to generate an enhanced digital signal.

  • Patent number: 10084423
    Abstract: Systems and methods provide a solution to a common nuisance of loud background noise encountered when watching television, allowing the issue to be solved with little or no user interaction. Systems and methods automatically modulate device volume based on background noise level. The systems and methods record a background level of noise, and if that background level of noise increases, the systems and methods automatically increase the content volume which had been set by the user. Exceptions are made for brief sounds or for viewer conversations.

  • Patent number: 10079030
    Abstract: A device may be configured to alert a user while the user is listening to audio over headphones. For example, the device may be configured to alert the user of the device, such as by reducing the volume of an audio signal output through the headphones and/or by providing a visual alert to the user on a display of the device. The device may compare a volume level of an outputted audio signal to a threshold. The device may activate a microphone based on the comparison of the volume level to the threshold. When the microphone is activated, the device may provide an alert to a user based on a determination that a received audio signal includes a portion that corresponds to a predetermined value.

  • Patent number: 10045116
    Abstract: A system includes a first earpiece having an earpiece housing configured to isolate an ambient environment from a tympanic membrane by physically blocking ambient sound, a microphone disposed within the housing and configured to receive a first ambient audio signal from the ambient environment, a processor operatively connected to the microphone wherein the processor is configured to receive the first ambient audio signal from the microphone and determine if the first ambient signal exceeds a threshold sound level, and a speaker operatively connected to the processor. In a first mode of operation the processor determines that the first ambient audio signal exceeds the threshold sound level and processes the first ambient audio signal to modify the first ambient audio signal. In a second mode of operation the processor determines that the first ambient audio signal does not exceed the threshold sound level and reproduces the first ambient audio signal at the speaker.
