    摘要： The present disclosure provides systems and methods for processing a signal. The system for processing a signal may include at least one microphone and at least one vibration sensor. The at least one microphone may be configured to collect a sound signal, and the sound signal may include at least one of user voice and environmental noise. The at least one vibration sensor may be configured to collect a vibration signal, and the vibration signal may include at least one of the user voice and the environmental noise. The system for processing a signal may also comprise a processor. The processor may be configured to determine a relationship between a noise component in the sound signal and a noise component in the vibration signal, and obtain a target vibration signal by performing, based at least on the relationship, noise reduction processing on the vibration signal.

    摘要： A method of real-time noise reduction including generating spectral data using temporally localized spectral representations of a received audio signal, determining detection of voice by comparing first and second filtered data, and generating noise-reduced audio output by attenuating noise based on the determined detection of voice. The first and second filtered data are formed by attenuating temporal variations of the spectral data based on, respectively, a first timescale and a second timescale. A noise reduction system, comprising processing circuitry configured to execute a method of real-time noise reduction to generate an output that is transmitted via an output port of the noise reduction system. A noise-reduction microphone comprising a housing having a transducer coupled to a processor therein to execute a method of real-time noise reduction, and an output port. A non-transitory computer-readable medium having instructions to cause a processor to perform a method of real-time noise reduction.

    摘要： The present subject matter provides a method for de-noising an audio visual speech. The method includes modeling a noise in the audio visual speech using a noisy speech from audio data associated with the audio visual speech to generate a reconstructed noise signal. The method includes estimating the reconstructed noise signal in the audio visual speech using an audio signal and a plurality of visual frames. The method includes partitioning the reconstructed noise signal into a plurality of windows and calculate an energy associated with each window. The method includes estimating a noise strength in each window by performing a soft max operation to obtain one or more refined audio features. The method includes fusing the one or more refined audio features and one or more visual features using the noise strength to generate an output that is passed through a decoder to obtain a de-noised audio visual speech.

    摘要： An apparatus configured to: identify a POI in an audio scene, wherein one or more input audio signals represent the audio scene and at least one further input audio signal represents at least part of the audio scene, wherein the POI comprises a portion of the audio scene to be replaced during rendering using reconstructed audio parameters; generate, from the at least one further input audio signal, one or more complementary audio parameters that represent the POI in the audio scene; process the one or more input audio signals to obtain input audio parameters so as to enable replacement of the POI using the one or more complementary audio parameters; and combine the one or more complementary audio parameters with the input audio parameters, to create reconstructed audio parameters, so as to replace the POI in the audio scene at least partially using the one or more complementary audio parameters.
