    摘要: A method and apparatus for recognizing an activity of a monitored individual in an environment are described including receiving a first acoustic signal, performing audio feature extraction on the first acoustic signal in a first temporal window, classifying the first acoustic signal by determining a location of the monitored individual in the environment based on the extracted features of the first acoustic signal in the first temporal window, receiving a second audio signal, performing audio feature extraction of the second acoustic signal in a second temporal window and classifying the second acoustic signal by determining an activity of the monitored individual in the location in the environment based on the extracted features of the second acoustic signal in the second temporal window.

    摘要: A recording is usually a mixture of signals from several sound sources. The directions of the dominant sources in the recording may be known or determined using a source localization algorithm. To isolate or focus on a target source, multiple beamformers may be used. In one embodiment, each beamformer points to a direction of a dominant source and the outputs from the beamformers are processed to focus on the target source. Depending on whether the beamformer pointing to the target source has an output that is larger than the outputs of other beamformers, a reference signal or a scaled output of the beamformer pointing to the target source can be used to determine the signal corresponding to the target source. The scaling factor may depend on a ratio of the output of the beamformer pointing to the target source and the maximum value of the outputs of the other beamformers.

    摘要: The present principles generally relate to audio apparatus, methods, and computer program products and in particular, to improvements that adjust the sound level or levels of one or more audio outputs of an audio system based on the determined origin and/or direction of propagation of a detected human voice in a location. Such an adjustment may be to decrease, mute, or increase the sound level of an audio output producing sound in the direction of the origin of the voice. A sound level produced by other audio outputs may be unchanged.

    摘要: A method and a system (20) of audio source separation are described. The method comprises: receiving (10) an audio mixture and at least one text query associated to the audio mixture; retrieving (11) at least one audio sample from an auxiliary audio database; evaluating (12) the retrieved audio samples; and separating (13) the audio mixture into a plurality of audio sources using the audio samples. The corresponding system (20) comprises a receiving (21) and a processor (22) configured to implement the method.
