Snapchat I'm frustrated don't know how to do voice change on my snaps love this app my phone is?

It's true, some of the filters have voice changers, so it depends. Furthermore, there are two other options to change your voice on snapchat: when you made a video, you just keep swapping your screen to the left or to the right and instead of a filter you can choose if the video plays more rapidly or in slow motion. You can imagine that in the 'skipped' option, your voice will sound high pitched and that in the slow motion version you will have a very low pitched voice.

Now, it's important that you keep swapping that screen until you see a bunny or a snail. When you swap to the left you can even play your snap video backwards. I hope this was helpful, have fun with snapchat!
