title: Some cross-linguistic evidence for modulation of implicational universals by language-specific frequency effects in phonological development.
abstract: While broad-focus comparisons of consonant inventories across children acquiring different language can suggest that phonological development follows a universal sequence, finer-grained statistical comparisons can reveal systematic differences. This cross-linguistic study of word-initial lingual obstruents examined some effects of language-specific frequencies on consonant mastery. Repetitions of real words were elicited from 2- and 3-year-old children who were monolingual speakers of English, Cantonese, Greek, or Japanese. The repetitions were recorded and transcribed by an adult native speaker for each language. Results found support for both language-universal effects in phonological acquisition and for language-specific influences related to phoneme and phoneme sequence frequency. These results suggest that acquisition patterns that are common across languages arise in two ways. One influence is direct, via the universal constraints imposed by the physiology and physics of speech production and perception, and how these predict which contrasts will be easy and which will be difficult for the child to learn to control. The other influence is indirect, via the way universal principles of ease of perception and production tend to influence the lexicons of many languages through commonly attested sound changes.
