NOISE REDUCTION IN A MICROPHONE USING VOWEL DETECTION

摘要

In an approach for reducing feedback in a device, wherein a first audio signal is received by a device. A processor determines that an intensity value of the first audio signal is increasing above a predetermined threshold value. A processor determines whether the first audio signal includes a vowel type sound. A processor responsive to determining that the first audio signal does not include the vowel type sound clips the first audio signal.

1. A method for reducing feedback in a device, the method comprising:
receiving, by one or more processors, a first audio signal in a device; determining, by one or more processors, that an intensity value of the first audio signal is increasing above a predetermined threshold value; determining, by one or more processors, whether the first audio signal includes a vowel type sound; and responsive to determining that the first audio signal does not include the vowel type sound, clipping, by one or more processors, the first audio signal.
