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 1):
A method of enhancing speech of a headphone user, the method comprising:\n receiving a primary signal derived from at least one microphone associated with the headphone, the primary signal configured to include a component of speech from the user; generating an echo reference signal by pre-filtering at least one playback signal, the at least one playback signal provided by an audio source to be rendered into an acoustic signal by an acoustic driver associated with the headphone; receiving a noise reference signal representative of acoustic noise in the environment of the headphone; and filtering the 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.
