Speech synthesizer program

I’m not sure exactly what I want, but hopefully you guys can help me out. The back story is me and a friend have always given each other prank gifts for birthdays, and it will soon be the friends birthday. I wanted to get the “object of his desires” to ask him to a date, but she wanted nothing to do with it. I realized then that it would have to be a one man job. So now I turn to you, how can I make myself sound more female over the phone. I was thinking along the lines of some sound editing software where I could say my message, tweak it a bit, and then call him up and play it. Does anyone have any ideas for a program that could do this? Or maybe a better way of doing it that I didn’t think of?

Thanks,

Is your friend really going to be fooled by a one-sided conversation? Here’s some ideas:

  1. Have a sex change operation. After recovering, make the call. Reverse operation if desired. (Drastic)

  2. Find a female that will make the call for you. (Ideal)

  3. Record the message with your voice, then use some software to change the pitch to make it sound female. This software says it can do just that. No experience with it, just Googled on “alter voice female”. (Use only if friend is a box of rocks)

Many gadget/electronic stores sell items that distort your voice. You would hold this in front of the phone while speaking. They are usually marketed as safety gadgets for little old ladies living alone. They also sell cheapo kids-toy versions in toy-stores. Try that mebbe?

Damn, Iteki, that’s what I was trying to find but didn’t succeed. I thought they didn’t make things like that anymore. But I was looking for something more like that one that Skeet Ulrich used in Scream.

You could always use a soundboard from Ebaum’s World.
