Perfect Prompts: Quick & Easy!

The Professional Prompt Editor
Sound Your Best!

Let VFEdit® turn your multimedia or voice processing PC into a voice prompt recording studio.

VFEdit (vee-ef-edit, for Voice File Editor) is a program that lets you edit sound the way a word processor lets you edit text. A word processor lets you to cut, copy, paste and re-arrange written words. VFEdit lets you do the same thing with spoken words—and a lot more.

Your voice system is only as good as it sounds. You want your audio presentations to sound good—just as you want your written presentations to look good. If you develop for voice processing, or if you only change, fix, and improve your voice prompts, you’ll find VFEdit just about indispensable.
