A semiconductor structure, such as a CMOS structure, includes a gate electrode that has a laterally variable work function. The telecommunication device is further configured to determine whether to handle the audio input as a command, as a request of a telecommunication device application, or as a network search request, the determining being based on one or more user-configurable rules or priorities. The operating section is capable of tilting in a radial direction from a reference position where the contact point is in a nonconductive state. The classification time represents the earliest time at which a classification can be made with a predetermined level of confidence.
