I’ve been using sound in my Intro to Physical Computing midterm. Below is a video of the interaction. The game lets you create new words to fit meanings that don’t have words yet. You build words by pressing different combinations of a mouth, teeth and tongue to unlock various consonants and vowels. There’s more to read about it over here!
Here’s an older iteration that shows the screen up close. If you hear a consonant or vowel you like, you can save it to a growing word at the bottom of the screen.
