Articulatory phonetics is a subfield of phonetics. "In studying articulation, phoneticians explain how humans produce speech sounds via the interaction of different physiological structures." Articulatory phonetics deals with the conversion of air flow through the vocal tract into sound. So they ask, how does the air coming out of the mouth transform into sound?

A phoneme is the smallest segmental unit of sound "employed to form meaningful contrasts between utterances."  A phoneme is a unit of speech that can distinguish a word. So changing one wound in a word can change its meaning (i.e. hit, sit, bit).

An allophone is a phonetic variant of a phoneme in a particular language. An allophone is not distinctive like a phoneme, but a variant. So changing the allophone of the word will not change the meaning, it will just make it sound odd.
