Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 6:
7. An electronic device comprising:
a plurality of microphones; and
a processor configured to:
analyze a plurality of audio signals output from a plurality of sources received through the plurality of microphones and obtain information on directions in which the plurality of audio signals is received and information on input times of the plurality of audio signals;
determine signal sizes and input duration times of the plurality of audio signals based on the information on the input times of the plurality of audio signals;
identify at least one audio signal having a signal size exceeding a predetermined size and having an input duration time exceeding a predetermined time;
determine whether each of the directions in which the plurality of audio signals is input, has been changed more than a predetermined angle among the identified at least one audio signal;
determine at least one source outputting an audio signal of which the determined direction in which the audio signal is input has been changed more than the predetermined angle;
determine a source outputting an audio signal having shortest input duration time among the at least one source as a target source for speech recognition; and
process an audio signal obtained from the determined target source,
wherein the processor is configured to:
based on at least one audio signal being input continuously for a preset time, increase counter of the at least one audio signal, the counter representing continuity of the at least one audio signal,
determine a source outputting an audio signal of which counter is lowest among the plurality of the audio signals as the source outputting the audio signal having the shortest input duration time.
