Either way it's interesting. It's called Sonotype. The expression of letters and sound. I was really thrown off by the concept at first. It is defined as a series of experimental typefaces that challenges the arbitrary relationship between verbal and visual communication. They use sonogram interpretations- that is a visual representation of speech. It's kind of confusing and bewildering, but the website is fun to play around with. Never drew a relationship between sound and typography like that before!
