Document Summary
The breaking up of the air stream into sounds of speech by the structures of the mouth. Primitive stage (birth 2 months) gurgle noises (1 4 months) cooing; mostly play with vowels, some consonants added; primarily back (velar) sounds. Canonical stage (3 8 months) more consonants added but little to no inflection. Nonreduplicated / variegated babbling (5 10 months) variegated babbling that leads to jargon; intonation added. Combine different words to make a word. Ex: cat is a morpheme and an s and get another morpheme cats. How many letters are in the word. Diphthongs = combination of vowels: ex: oy as in boy, vowels that slide into another. Vowels specified by anterior-posterior (front-back) plane tongue movement is vitally important for the articulation of vowels cranial-caudal (high-low) plane lip opening. Usually moves in the same way that the tongue moves. Have more of a jaw opening when the tongue is pushed low.
