The present disclosure provides a method and system for voice enhancement. The method and system of the present disclosure may simultaneously perform signal processing of two paths on an input signal. The first path signal processing includes receiving an audio source input and performing dynamic loudness balancing on the audio source input based on a first gain control parameter. The second path signal processing includes: performing voice detection on the audio source input and calculating a detection confidence; and calculating a second gain control parameter based on the detection confidence. The first path signal processing and the second path signal processing may be synchronous or asynchronous. The method of the present disclosure also includes updating the first gain control parameter with the second gain control parameter calculated by a second processing path and performing the first path signal processing based on the updated first gain control parameter.

Abrégé

Training a user-specific perturbation generator for an audio feature detection model includes receiving one or more positive audio samples of a user, each of the one or more positive audio samples including an audio feature; receiving one or more negative audio samples of the user, each of the one or more negative audio samples sharing an acoustic similarity with at least one of the one or more positive audio samples; and adversarially training a user-specific perturbation generator model to generate a user-specific perturbation, the training based on the one or more positive audio samples and the one or more negative audio samples. Perturbing audio samples of the user with the user-specific perturbation can cause an audio feature detection model to recognize the audio feature in audio samples that include the audio feature and/or to refrain from recognizing the audio feature in audio samples that do not include the audio feature.

Various embodiments include techniques for recovering a cryptographic key in a system that includes secure storage. A computer system implementing these techniques determines that the cryptographic key stored in a first secure storage is corrupted. The computer system retrieves an emergency key from a second secure storage. The computer system establishes communications with a server by using the emergency key.

Abrégé

A method and system for controlling power delivery to an electronic device having default and proprietary power modes. A default power delivery protocol between the power delivery adapter and the electronic device is completed upon connecting the power delivery adapter to the electronic device. When a proprietary power mode is available, it is verified and communicated to the power delivery adapter, wherein the power delivery adapter delivers power to the electronic device according to the proprietary power mode. When a proprietary power mode is not available, the power delivery adapter continues to deliver power in the default mode.

Abrégé

In at least one embodiment, an apparatus for providing a virtual sound effect in a listening environment is provided. The apparatus includes at least one controller and an audio playback device. The audio playback device includes the at least one controller that is programmed to receive an audio input signal from an audio input source and to apply a head related transfer function (HRTF) to the audio input signal. The at least one controller is further programmed to apply crosstalk cancellation to the audio input signal and to generate an audio output signal after applying the HRTF and the crosstalk cancellation to the audio input signal for playback by at least one loudspeaker that is invisible to a listener in the listening environment.

Abrégé

A computing device for adjusting audio output in a listening environment having a user interface to select a source, from a plurality of sources, to be played at a sound zone in a plurality of sound zones; A processor receives user input source selections to determine combined sources for the plurality of sound zones and adjust audio parameters for the sound zones having combined sources based on combined sources and individual inputs for audio settings from each sound zone. The processor applies adjusted audio parameters to a sound zone algorithm for the sound zones having combined sources, and outputs audio based on the adjusted sound zone algorithm. A designated occupant may select the sound zones to which the adjusted sound zone algorithm is to be applied.
