Echoes makes it easy to send quick voice announcements to other Macs running Echoes on your local network. Echoes is different from Skype, FaceTime, and other voice chat applications because it eliminates "dialing" or setting up connections with your recipients. Echoes puts an icon in your menu bar where you just choose "Announce" (or press a convenient keyboard shortcut), speak your announcement, and press return. Its fast and easy.
