Typology 1: Stark Assessment of Early Vocal Development [7] consists of 5 phases. Reflexive (0 to 2 months of age) consisting of crying, fussing, and vegetative sounds; Control of phonation (1 to 4 months of age) consonant-like sounds, clicks, and raspberry sound; Expansion (3 to 8 months of age) isolated vowels, two or more vowels in a row ...
