Title: MICROPHONE ASSEMBLY WITH AUTHENTICATION
Abstract:
A microphone assembly is disclosed including a microelectromechanical system (MEMS) transducer and an electrical circuit disposed in a housing having an external-device interface. The electrical circuit is configured to determine whether a speech characteristic is present in an electrical signal produced by the transducer, attempt to authenticate the speech characteristic, and provide an interrupt signal to the external device interface only upon successful authentication of the speech characteristic.
