Speechtherapist Cards

Description: A working schematic of speech, drawn the way acoustic phonetics models it: lungs as the power supply, a voicing switch between the vocal folds and a noise source, and three formant filters tuned by the jaw, the tongue and the lips. Footnote 1 is for every speech-language pathologist who has spent a whole session on one sound: F3 drops lowest for /r/. Made for SLPs, SLPAs and grad students who like a diagram that is actually true.
