AV Voice Changer Software is unique, making it worth a download. This outstanding tool helps you change your voice. AV Voice Changer Software lets you greet people entering your Web site or narrate an online presentation in whatever voice you choose. The trial version has some irritating aspects, such as the need to download a free key to open it and a nag screen three times bigger than the program window. Despite this, the software turns out to be really good. It provides male and female voices of various ages, as well as Ghost, Hall, Underwater, and Cave effects, among others. We're not sure what the Troika effect is supposed to be, since that's just the Russian word for "three." Despite a slightly chaotic interface, AV Voice Changer Software is unique, making it worth a download.
