Patent ID: 8577062

Claim:
A method for personalized voice operable control, the method comprising the steps of: capturing an ambient sound from at least one Ambient Sound Microphone (ASM) to produce an electronic ambient signal; delivering audio content to an ear canal by way of an Ear Canal Receiver (ECR) of an earpiece to produce an acoustic audio content; capturing in the ear canal an internal sound from at least one Ear Canal Microphone (ECM) to produce an electronic internal signal, wherein the electronic internal signal includes an echo of the acoustic audio content and a sound signal; suppressing the echo of the acoustic audio content in the electronic internal signal to produce a modified electronic internal signal containing the sound signal; detecting a presence of a spoken voice signal generated by a wearer of the earpiece in the modified electronic internal signal based on an analysis of both the electronic ambient signal and the modified electronic internal signal, the analysis including comparing the modified electronic internal signal to the electronic ambient signal to determine whether the sound signal originates in the ear canal or external to the ear canal, the sound signal indicating the presence of the spoken voice signal when the sound signal originates in the ear canal; and controlling at least one voice operation of the earpiece if the spoken voice signal is detected.
