Assignee: THE TRUSTEES OF COLUMBIA UNIVERSITY IN THE CITY OF NEW YORK
Field: Computer technology (Electrical engineering)
Classification: CPC G  A | IPC G

Claim 12:
13. A system comprising:
at least one microphone to obtain a combined sound signal for signals combined from multiple sound sources in an area in which a person is located;
one or more neural sensors to obtain neural signals for the person, the neural signals being indicative of one or more target sound sources, from the multiple sound sources, the person is attentive to; and
a controller in communication with the at least one microphone and the one or more neural sensors, the controller configured to:
determine a separation filter based, at least in part, on the neural signals obtained for the person; and
apply the separation filter to a representation of the combined sound signal to derive a resultant separated signal representation associated with sound from the one or more target sound sources the person is attentive to;

wherein the controller configured to determine the separation filter is configured to derive, using a trained learning model, a time-frequency mask that is applied to a time-frequency representation of the combined sound signal, including to derive the time-frequency mask based on a representation of an estimated target envelope for the one or more target sound sources the person is attentive to, determined based on the neural signals obtained for the person, and based on a representation for the combined sound signal.
