Abstract

An inertial sensor unit, including a sensor element for detecting and converting movements and vibrations into an electrical sensor signal, a signal processing element for evaluating the sensor signal, and an interface for signaling a detected speech activity. The signal processing element includes a first processing stage which checks a first criterion for the presence of a speech activity, and a second processing stage which checks a second criterion for the presence of a speech activity, the second processing stage being passed through only if the sensor signal has passed through the first processing stage and the first criterion for the presence of a speech activity has been met. The signal processing element is designed to activate the interface for signaling a speech activity only if the sensor signal has passed through the second processing stage, and the second criterion for the presence of a speech activity has been met.
