To understand the interactions between production patterns common to children regardless of language environment and the early appearance of production effects based on perceptual learning from the ambient language requires the study of languages with diverse phonological properties. Few studies have evaluated early phonological acquisition…

This study compared segmental distribution patterns for consonants and vowels in English infant-directed speech (IDS) and adult-directed speech (ADS). A previous study of Korean indicated that segmental patterns of IDS differed from ADS patterns (Lee, Davis & MacNeilage, 2008). The aim of the current study was to determine whether such differences…

Compares sound patterns in the speech of two Brazilian-Portuguese speaking children with early production patterns in English-learning children as well as English and Brazilian-Portuguese characteristics. Results emphasize the primacy of production system effects in early acquisition, although even the earliest word forms show evidence of…

Purpose: Vocalization development has not been studied thoroughly in infants with early-identified hearing loss who receive hearing aids in the 1st year of life. This study sought to evaluate the relationship between auditory sensitivity and prelinguistic vocalization patterns in infants during the babbling stage. Method: Spontaneous…

Vowel production of a 14-month-old girl was studied over a 6-month period. Sixty percent of the vowels were produced correctly. A complex pattern of vowel preferences and errors was partially related to prespeech babbling preferences and strongly related to word structure variables (monosyllabic versus disyllabic).

Presents evidence for four major design features of serial organization of speech arising from comparison of babbling and early speech with patterns in ten languages. Maintains that no explanation for the design features is available from Universal Grammar; except for intercyclical consonant repetition development, perceptual-motor learning seems…

Examines the phonetic characteristics of babbling by a pair of fraternal twins raised in a bilingual environment (English/Serbian). The study focused on the basic articulatory form of babbling, the impact of twinship on babbling patterns, and whether effects specific to one or another of the ambient languages could be observed.
