Abstract
An automated voice operated transmitter control (VOX) arrangement devoid of any separate manual actuation requirement and adaptable to a dynamic acoustic environment is described. The VOX decides whether it should be operating, automatically selects a threshold condition (70) from a predetermined list according to a average acoustic signal level over a first time period, and provides a VOX PTT signal to activate a radio frequency transmitter (24) when the acoustic signal level, over a second time period that is less than the first time period and exceeds a debounce time (78), exceeds the threshold condition.
