PZTVoice Voice Keyer |

PZTVoice - Voice Keyer for Opto-Interfaces

A very basic, free and open-source application written in Visual Basic 6 that allows you to transmit 4 pre-recorded voice messages over the air.  You can press F1-F4 to start the message, Escape to stop or use the mouse.  A simple timer and progress-bar displays the playback position.  The source-code is fairly well commented!
