摘要： A method for blind source separation based spatial filtering on an electronic device includes obtaining a first source audio signal and a second source audio signal. The method also includes applying a blind source separation filter set to the first source audio signal and to the second source audio signal to produce a spatially filtered first audio signal and a spatially filtered second audio signal. The method further includes playing the spatially filtered first audio signal over a first speaker to produce an acoustic spatially filtered first audio signal and playing the spatially filtered second audio signal over a second speaker to produce an acoustic spatially filtered second audio signal. The acoustic spatially filtered first audio signal and the acoustic spatially filtered second audio signal produce an isolated acoustic first source audio signal at a first position and an isolated acoustic second source audio signal at a second position.

摘要： A device includes one or more processors configured to perform signal processing including a linear transformation and a non-linear transformation of an input signal to generate a reference target signal. The reference target signal has a linear component associated with the linear transformation and a non-linear component associated with the non-linear transformation. The one or more processors are also configured to perform linear filtering of the input signal by controlling adaptation of the linear filtering to generate an output signal that substantially matches the linear component of the reference target signal.

摘要： A device includes a memory configured to store category labels associated with categories of a natural language processing library. A processor is configured to analyze input audio data to generate a text string and to perform natural language processing on at least the text string to generate an output text string including an action associated with a first device, a speaker, a location, or a combination thereof. The processor is configured to compare the input audio data to audio data of the categories to determine whether the input audio data matches any of the categories and, in response to determining that the input audio data does not match any of the categories: create a new category label, associate the new category label with at least a portion of the output text string, update the categories with the new category label, and generate a notification indicating the new category label.

摘要： A method of operation of a device includes receiving an input signal at the device. The input signal is generated using at least one microphone. The input signal includes a first signal component having a first amount of wind turbulence noise and a second signal component having a second amount of wind turbulence noise that is greater than the first amount of wind turbulence noise. The method further includes generating, based on the input signal, an output signal at the device. The output signal includes the first signal component and a third signal component that replaces the second signal component. A first frequency response of the input signal corresponds to a second frequency response of the output signal.
