When I was a teenager, I always found myself much better at talking to people over online instant messengers like AOL Instant Messenger than in real life. In real life, I was awkward. Online, I was a George Clooney.
I decided to create a version of me that speaks whatever I typed. I recorded a short video of me saying the phonetic sounds of each letter of the alphabet. I then associated each alphabetic key on the keyboard to the specific timestamp of when I said the corresponding letter.
It ended up being more of a beatbox soundboard thing, but if you type at the right cadence, it sounds kind of like English.
