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.
My six year old daughter is getting the hanging of the spelling and whatnot, but earlier on in her Kindergarten year, words like "driver," to her, started with a J. I had never thought about it, but it absolutely (at least in our NJ dialect) has a J sound, because, as you say, we all talk fucked up (paraphrasing).
