| summary | It is generally thought that fricatives are acquired later than stops, only reaching adult-like status around the age of 5-7 years in American English. This later acquisition has been attributed to the need to develop fine-grain motor control of the tongue to keep the appropriate constriction size for generating turbulence noise. However, most studies on the acquisition of fricatives have been carried out employing spectral analysis of fricative onsets; little is known about the acquisition of fricative codas, and/or about the non-spectral aspects of these segments. This is all the more important for a language like English, where many grammatical morphemes are represented by /s, z/ (e.g., plurals, 3rd person singular, possessives). This paper presents findings on the durational aspects of mothers’ and 1;6-2;6-year-old children’s spontaneous use of alveolar fricatives in both morphemic and non-morphemic contexts. Although children’s fricatives tend to be longer and more voiced compared to those of their mothers, the voicing and morphological contrasts for fricative codas are early acquired. The implications for hearing aided children, where high-frequency noise is not transmitted, are discussed. |
