New Apple Patent Equips Headphones With Accelerometer To Recognise When Your Speaking

A new patent that has been registered by Apple that indicates the company is working on a new technology designed to enable their headphones to recognise when a user is talking.
The Apple patents reveal that a future design of their headphones, which are included with Apple’s mobile devices could include an accelerometer to help identify and recognise the voice activity.

As soon as the headphones recognise a user talking this would then activate and June beam forming microphone arrays explains the penitent which has been published by the U.S. Patent and Trademark Office this week called “System and method of detecting a user’s voice activity using an accelerometer”. The patent explains:

“A method of detecting a user’s voice activity in a mobile device is described herein. The method starts with a voice activity detector (VAD) generating a VAD output based on acoustic signals received from microphones included in the mobile device and data output by an inertial sensor that is included in an earphone portion of the mobile device.

The inertial sensor may detect vibration of the user’s vocal chords modulated by the user’s vocal tract based on vibrations in bones and tissue of the user’s head. A noise suppressor may then receive the acoustic signals from the microphones and the VAD output and suppress the noise included in the acoustic signals received from the microphones based on the VAD output. The method may also include steering one or more beamformers based on the VAD output. Other embodiments are also described.”
