Obscuring voices

I have a simple production in which we are using sillouetted individuals and want to protect their "identities" by obscuring voices. I need to produce 5 different video segments (all one shoot). The video part of it is quite simple.

I've never had to deal with this type of sound issue before. I am using Sony Vegas for my video edit, and I occasionally use the Acid looping software, but I have not had to do too much sound production other than adjusting mix levels. Is there something straightforward I can use in Vegas or Acid, or do I need to get Sound Forge?

Thanks much in advance!

You could use Audacity (free from sourceforge.net) to apply a pitch shift.

Which, of course, can be pitch shifted back to normal if someone has access to the audio. :)

some flange, distortion, pitch shift, alone, or in combinations. I would just play with some of the effects until you like how it sounds.

Use a vocoder plug-in. Since it mixes the original voice with another sound, retrieving the original voice would be virtually impossible.

Vocoders have been around for years... finding uses in radio jingles, the Cylon voices in the original Battlestar Galactica series, popular music, etc.

The better quality vocoders have more bands of frequencies to work with.

Do an internet search on the term and you'll find more than you ever wanted to know.
