Phonological Acquisition A Stages of Development

As noted previously, it is generally agreed that there is essential continuity between prelinguistic babbling and the earliest stages of phonological development evidenced in the child's first words. The majority of sounds produced in the earliest words of children are the same as those preferred in their babbles. Initially, children's words are composed of simple CV syllable structures, using a relatively small inventory of sounds. Gradually, over time and with growth in the child's vocabulary, there is an expansion in the range of sounds produced by children. Although there is no universal order in the acquisition of phonological features, certain regularities have been found in the phonological sounds that are used across children. Mastery over vowels occurs before consonants. The main consonant classes that are used earlier in development include stops (e.g., b and d), nasals (e.g., m and n), and glides (e.g., w). Later developing consonants include fricatives (e.g., v) and liquids (e.g., l and r).
