Abstract
At least one exemplary embodiment is directed to an acoustic device including an ear canal microphone configured to detect a first acoustic signal, an ambient microphone configured to detect a second acoustic signal, and a processor operatively coupled to the ear canal microphone and the ambient microphone. The processor is configured to detect a predetermined speech pattern based on an analysis of the first acoustic signal and the second acoustic signal and upon detection of the predetermined speech pattern, subsequently process acoustic signals from the ear canal microphone for a predetermined time or until the ear canal microphone detects a lack of an acoustic signal for a second predetermined time. After the predetermined time or after a second predetermined time, the processor processes acoustic signals from the ear canal microphone and the ambient microphone.
