A holistic view of phonological development can be attained only through exploration of the relationship between universal developmental sequences, to establish a general pattern of development and individual learning and to provide information regarding variability. This study examined consonant cluster production, looking specifically at the relationship between general trends and individual differences as children acquire these sounds. The spontaneous speech of 16 normally developing Anglo-Australian 2-year-olds was elicited monthly for 6 months, and the corpus of 96 samples was examined using independent and relational phonological analyses. Data demonstrated that 2-year-olds were able to produce a range of consonant clusters in word-initial and word-final position, but few of the younger participants could produce consonant clusters correctly. Only half of the participants showed an increase in the percent of consonant clusters produced correctly over the 6-month period; however, their developing phonological maturity was revealed in the increase in the range and diversity of their repertoire of consonant clusters and by their closer approximations to the adult target. Specific findings of the study were compared to 10 trends for children's acquisition of consonant clusters emerging from the literature over the last 70 years. KEY WORDS: normal development, consonant clusters, phonology, speech, variability, This article presents findings about the route of acquisition consonant clusters by normally developing 2-year-olds. Normal speech and its acquisition have been the foundation of speech-language pathologists' practice for one [...]

Purpose: The ability of 5- and 6-year-old male children (23 participants) between the chronological ages of 5;0 and 6;11 (years;months) with childhood apraxia of speech (CAS; n = 9) and with typical development (TD; n = 14) to detect differences in vowel duration of syllable pairs is explored. We asked whether the children with CAS show different patterns of performance on the vowel duration difference experimental task than those of their similarly aged peers with TD. Method: A male adult audio-recorded the syllable /ba/. The /a/ was digitally lengthened and shortened, while maintaining uniform fundamental frequency and amplitude of the vowel and duration of the consonant /b/ at 42 ms. Vowel lengths increased in 40-ms increments, ranging from 208 to 488 ms. Eight pairs of syllables, 1 with equal length and 7 with differing vowel lengths, were randomly presented to the children 10 times in blocks of 16 pairs via a computer application. Results: Numerous complementary analyses indicated patterns of performance differed for children with CAS compared to the children with TD. The children with CAS were notably less accurate in their duration discrimination and evidenced greater variability in their performances across duration difference conditions than their peers with TD, signifying they were generally challenged to discriminate the vowel duration differences. Conclusion: These results suggest that CAS, which is more generally considered a motor speech disorder, may have a perceptual component of CAS related to vowel duration discrimination. Further research directions and clinical implications are discussed. [ABSTRACT FROM AUTHOR]

Purpose: This study investigated the opinions of high school teachers regarding the relative importance of selected communication skills for their students' communication with them and explored if the content areas in which the teachers taught or the amount of high school teaching experience they had were associated with their opinions. Method: Teachers ranked 14 communication skills according to perceived order of importance for Grade 10 adolescents' communication with them as teachers. Results: Teachers tended to perceive skills associated with discourse management strategies as relatively more important than other skills. The two communication skills that were associated with metalinguistic/figurative language aspects of communication were ranked as least important. Inexperienced and experienced high school teachers tended to rank the importance of the communication skills similarly, as did sciences and humanities teachers, except for the communication skill of turn taking, which sciences teachers ranked higher than humanities teachers. Clinical Implications: The results provide guidelines for developing intervention approaches that can facilitate successful communicative interactions in high school environments and target goals that teachers of adolescents with language and/or learning disabilities perceive as more important for teacher-adolescent interactions.

Children's acquisition of adult-like speech production has fascinated speech-language pathologists for over a century, and data gained from associated research have informed every aspect of speech-language pathology practice. The acquisition of the consonant cluster has received little attention during this time, even though the consonant cluster is a common feature of speech, its acquisition is one of the most protracted of all aspects of children's speech development, and the production of consonant clusters is one of the most common difficulties for children with speech impairment. This paper reviews the literature from the past 70 years to describe children's normal acquisition of consonant clusters. Articulatory, phonological, linguistic, and acoustic approaches to the development of consonant clusters are reviewed. Data from English are supplemented with examples from other languages. Consideration of the information on consonant cluster development revealed 10 aspects of normal development that can be used in speechlanguage pathologists' assessment and analysis of children's speech.
