Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 7:
8. A system for processing sound data, the system comprises:
a processor; and
a memory storing computer-executable instructions that when executed by the processor cause the system to:
receive predetermined spectrogram data of sound data for training, wherein the sound data comprises a plurality of sound sources, and wherein one sound source of the plurality of sound sources is dominant at a first set of time frequency points and at a second set of time frequency points;
generate, based on training, a convolutional neural network (CNN) using the received predetermined spectrogram data,
wherein the convolutional neural network includes parameters,
the convolutional neural network generates a plurality of embedded vectors as output based on the received predetermined spectrogram as input,
the plurality of embedded vectors includes a first set of embedded vectors corresponding to the first set of time frequency points and a second set of embedded vectors corresponding to the second set of time frequency points, and
the parameters are configured to generate the first set of embedded vectors corresponding to the first set of time frequency points to be within a predetermined threshold of deviation from the second set of embedded vectors corresponding to the second set of time frequency points at which the one sound source of the plurality of sound sources is dominant; and

provide the plurality of embedded vectors as output.
