How to Change your Voice to another normal Voice

[UmmAddan]

Hi, i want to start posting videos on youtube with a voice over.
only thing is i don't want to have my voice on it. apart from getting someone else to read out the instructions, is there a way of me reading them myself but having my voice changed to another NORMAL voice.
i tried the text to speech softwares but they are just naff to be honest.
i want to it to sound as realistic as possible so it doesn't seem like i'm taking the mick.
Thanks.

There are vocoder tools that might help, or you could use Audacity and simple pitch shift your voice up or down. To be fair though, there is a limit to what you can do to your voice and still have it sound normal.

Pitch shift up or down one semitone works pretty good, like mentioned above.
