Abstract
A method of isolating voice signal from a user, the method including capturing a first audio signal by a first microphone; capturing a second audio signal by a second microphone, the second microphone located at a distance from the first microphone; transmitting the first audio signal from the first microphone and the second audio signal from the second microphone to a processor; comparing, by the processor, the first audio signal and the second audio signal with a time delay corresponding to the distance between the first microphone and the second microphone; and finding a commonality between the first audio signal and the second audio signal if the first audio signal and the second audio signal are substantially different.
Claims13
An electronic device comprising:
- a first microphone configured to capture a first audio signal;
- a second microphone configured to capture a second audio signal, the second microphone located at a distance from the first microphone;
- and
- a processor in communication with the first microphone and the second microphone, the processor configured to receive the first audio signal from the first microphone and the second audio signal from the second microphone;
- wherein the processor is further configured to:
- compare the first audio signal and the second audio signal with a time delay corresponding to the distance between the first microphone and the second microphone;
- and
- generate an isolated audio signal by finding a commonality between the first audio signal and the second audio signal if the first audio signal and the second audio signal are substantially different.
