Abstract
Methods and devices for voice operated control are provided. The method can include measuring an ambient sound received from at least one Ambient Sound Microphone, measuring an internal sound received from at least one Ear Canal Microphone, detecting a spoken voice from a wearer of the earpiece based on an analysis of the ambient sound and the internal sound, and controlling at least one voice operation of the earpiece if the presence of spoken voice is detected. The analysis can be a sound pressure level (SPL) difference, a correlation, a coherence, or a spectral difference.
