xkcd #2942: Fluid Speech
Alt text:
Thank you to linguist Gretchen McCulloch for teaching me about phonetic assimilation, and for teaching me that if you stand around in public reading texts from a linguist and murmuring example phrases to yourself, people will eventually ask if you're okay.
I'd say part of this is the intended / official descriptipn isn't actually that. The spoken word existed first, then someone tried to capture that spoken word using a finite list of characters and character combinations that map back to phenomes. The written word isn't phonetically accurate to the letters it is composed of, and the written word is just close approximation of the spoken word itself.
