In American English, the word familiar is normally pronounced as /fəˈmɪl.jɚ/. Recently, though, I've noticed more people pronouncing it as /fɚˈmɪl.jɚ/ ("fermiliar"), an alternate pronunciation listed on Wiktionary. Looking through YouGlish, this seems to be uncommon, but certainly well-attested; for some examples of this pronunciation, see this video at 6:55 or this video at 0:15.
So: how did this unusual pronunciation come about? Is it a general process, or something specific to this one word?
