To become a native speaker, beyond obligatory rules, children need to learn systematic variation in the language, as it is present at all levels of language structure and is an integral part of linguistic knowledge. To give an example in English, speakers sometimes pronounce words ending in -ing with -in' (e.g., working vs. workin') depending on…

Research attempting to understand the intermediate stages of first-language acquisition and disordered speech has led to the discovery of covert contrast. A covert contrast is a statistically reliable difference between phonemes that is produced by a language learner, but in a way that cannot be heard readily by a listener of the target language.…

Studies on the acquisition of Spanish as a first language do not agree on the patterns and factors relevant for coda development. In order to shed light on the questions involved, a longitudinal study of coda development in Northern European Spanish was carried out to explore the relationship between accuracy, markedness and frequency. The study…

Learners frequently experience phonologically inconsistent input, such as exposure to multiple accents. Yet, little is known about the consequences of phonological inconsistency for language learning. The current study examines vocabulary acquisition with different degrees of phonological inconsistency, ranging from no inconsistency (e.g., both…

The early development of vocalic and consonantal production in Mandarin-learning infants was studied at the transition from babbling to producing first words. Spontaneous vocalizations were recorded for 24 infants grouped by age: G1 (0 ; 7 to 1 ; 0) and G2 (1 ; 1 to 1 ; 6). Additionally, the infant-directed speech of 24 caregivers was recorded…

A study of the phonetic changes occurring when a speaker attempts to revise an unclear word for a listener focuses on changes made in the sound segment duration to maximize differences between phonemes. In the study, five-year-olds were asked by adults to revise words differing in voicing of initial and final stop consonants; a control group of…

Paper presented before the Indiana University Linguistics Club on May 13, 1971, in Bloomington, Indiana. (VM)

A study was conducted of the development of consonant clusters in the phonology of a native English-speaking child. His progress was studied over a year and a half period, in three one-month segments. His speech was recorded by tape and transcribed. Techniques used to elicit consonant clusters included real word imitation, imitation of nonsense…

This article discusses children's phonological limitations, including perceptual difficulties and productive difficulties. (NCR)

A study compared the Swedish tone accent acquisition of native-speaking children (N=2) and nonnative speaking college students (N=12). Both groups overgeneralized one pitch pattern to all bisyllabic words. Children used "Accent 2" (two-peaked) and adults "Accent 1" (one-peaked), analogous to the prevailing patterns of their…

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). (Author/JDD)

A study of the babbling and phonological development of 54 infants used half-hour videotape recordings of the children at play in their own homes. The vocal output was phonetically transcribed twice for interrater agreement, and analyzed for the consonants used five times or more in the child's vocal repertoire. These consonants were considered to…

Thirteen Mexican-American children in Corpus Christi, Texas, most approximately six years old, were interviewed in Spanish for the purpose of establishing the phonology of their dialect. The linguistic competence of the children, not their performance, was of primary interest. A phonological chart was devised based on the data derived from the…

The system of deriving baby speech from adult speech is discussed. The theory is based on the system of consonantal replacements. (NCR)

Analysis of French spoken by French girls aged 11-12 years found that, unlike older counterparts, theirs shows variable linguistic behavior on the phonological level that suggests avoidance of vernacular forms, the "sociolinguistic gender pattern." However, one speaker's discourse shows manipulation of conversational tone comparable to adult…
