This project was inspired by when I watch a video about a speech jammer on youtube. A speech jammer works by playing back audio from a microphone to the speaker at a small delay, causing the speaker to stumble in their talking. An online version of this can be found here. https://www.clicktorelease.com/code/speech-jammer/
To make this project I first started out by playing back audio at a slightly delayed time. Then I created a video that would also play back at a delay. I used math to sync up these delays. In order to make it more difficult to speak when using this system, I also created a feedback for the audio and an echo for the video. I connected both of these to scale appropriately.
When the delay is around 100 ms it is hardest to keep speaking normally, so the frame delay should be set to 32. However, if you want to experiment with the delay you can change it to any number from 0-32 where 0 is a longer delay and 32 is a shorter one.
I would encourage you to give it a try! Note that it is a lot harder to talk normally at first but you can get used to it pretty quickly. Also speaking off the top of your head is harder than doing something like reading. Have fun!
