I have a sound blaster live 5.1 card and you can have those effects, how ever you would need to record the audio track process it the add it back to the video I don't know what programs you would need.How do you make your voice on your video make it sound like a chipmunk?
get audacity(it is free, Google it) and put your video in and change it, i personally don't use that, i use adobe soundbooth, and if it doesn't except the video convert it to audio and then use a program like adobe premiere pro or windows movie maker or a video editing program and make sure u have the video without the audio and the audio without the video in separate files and just insert it on the time line and render, oh i almost forgot u can use something like voice changer 6.0 diamond for changing your voice in real time
you record it and speed it up. If you're using Windows, you can got to Start, All programs, accessories, entertainment, Sound Recorder.


Sound recorder can record from your mic and has an effect setting to speed it up.
