Two-way radio communication device, e.g. personal transceiver, has speech recognition stage providing voice operated switching from receive to transmit

摘要

The radio communication device has a speech-controlled transmitter with a speech storage module (41) coupled to a microphone amplifier circuit (B) on the input side and to a transmission/reception circuit (A) on the output side. A speech recognition circuit (42) is coupled to the input of the speech storage module, for controlling a transmitter control circuit (43) so as to provide voice-operated transmit-receive switching.
