Abstract
The audio input system (6) of a terminal, such as a mobile telephone, is powered up during the standby mode, either with the paging channel or any other short duration channel such as a monitoring channel, and is then used to recognize narrow bandwidth sounds such as a whistle, to activate the telephone. Once activated, the telephone may then be responsive to voice commands and may then support a speaker phone mode of application.
