I visited some site and it said that motorola t5500 two way radio has automatic voice recognition something
That means that it will Transmit, like pressing the "Talk" button, BUT ONLY when it hears the "Voice" it was "Trained" on. So this is so No-one else could use this unit. With this method. You "Identify" yourself, and after that every-time you speak, the Transmitter is keyed, and the channel is opened and the voice sent, when you stop talking,it goes back to receive, again. Some are less sophisticated, in that they are really a "Sound Switch" and when the unit "Hears" a "Voice" it, switches OFF receive, and ON the transmitter, and Transmits the audio out.
