[email protected] ABSTRACT earliest phases of speech acquisition lies in the potential for understanding the most complex system of serial Universal phonetic patterns can be observed in babbling action accomplished by the body when it is in its and early speech when infants produce rhythmic formative, and potentially most simple, phases of vocalizations that show structural similarities as well as expression. These early rhythmic vocal sequences can be differences from mature speakers. The Frame/Content seen as exploitation of the most basic characteristics of the perspective [1] illuminates underlying principles production mechanism by an immature organism in order motivating intrasyllabic, consonant and vowel patterns to accomplish serial action. Comparative methodologies observed in these early speech-like vocal sequences. focusing on similarities and differences between infant According to this perspective, lack of articulator vocal patterns and language patterns can reveal potentially movements independent of the mandible in vocal universal phonetic structures that have been retained in sequences result in intrasyllabic co-occurrences of labial patterning even as the pressure for message complexity consonants with central vowels, coronal consonants with increases in mature speakers. In this regard, the front vowels, and dorsal consonants with back vowels. As comparison of pre-linguistic vocal patterns, when there is complexity emerges in consonant clusters, vocal no message transmission involved, with earliest message- sequences retain regularities of patterning predicted by the related patterns in early words, can also potentially help to Frame/Content perspective.
