Abstract:
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.
