Voice prompts are quickly becoming more prevalent on two way radios introduced to the market today, and Vertex Standard is on top of this technology, building it into their eVerge series. The EVX-531, EVX-534 and EVX-539 digital radios all have Channel Announce, a feature that vocally announces the name and number of the channel you are on when you switch channels.
