Advanced Forms

Approximate Age of emergence: 10 - 18 months

Advanced Forms are more complex and speech-like than earlier developing vocalization types. For example, the closed syllable (CVC) is more complex than the open (CV) syllables of the canonical stage. Improved articulatory control is also apparent in diphthongs and jargon - a multisyllabic vocalization that contains a mix of different consonants and/or vowels overlaid with changes in intonation. Advanced Forms, along with earlier developing vocalizations, continue to be produced as children begin to say meaningful words.

Take a listen to some examples below:
