Abstract:
A headphone, headphone system, and method is provided to enhance speech pick-up from a user of a headphone, by removing noise and echo components. A primary signal is derived from at least one microphone associated with the headphone. The primary signal is configured to include a component of speech from the user. A noise reference signal is representative of acoustic noise in the environment of the headphone. A playback signal is provided by an audio source to be rendered by an acoustic driver associated with the headphone, and an echo reference signal is representative of the playback signal. The systems and methods filter the primary signal to reduce noise and echo components, based on the noise reference signal and the echo reference signal, respectively, to provide a voice estimate signal.

Claim (Index 11):
An audio system, comprising:\n at least one left microphone coupled to a left earpiece to provide a left primary signal; at least one right microphone coupled to a right earpiece to provide a right primary signal; and a signal processor configured to:\n receive at least one playback signal, \n derive an echo reference signal by pre-filtering the at least one playback signal, \n provide a combined signal from the left and right primary signals, \n provide a noise reference signal from the left and right primary signals, and \n filter the combined primary signal to reduce components correlated to the noise reference signal and to reduce components correlated to the echo reference signal, to provide a voice estimate signal.
