Intonation has been little studied in children with speech and language impairments, although deficits in related aspects of prosody have been hypothesized to underlie specific language impairment. In this study a new intonation battery, the Profiling Elements of Prosodic Systems-Child version (PEPS-C), was administered to 18 children with speech and/or language impairments (LI). PEPS-C comprises 16 tasks (8 x 8, Input x Output) tapping phonetic and functional aspects of intonation in four areas: grammar, affect, interaction, and pragmatics. Scores were compared to a chronological age (CA) matched group of 28 children and a group of 18 children matched for language comprehension (LC). Measures of language comprehension, expressive language, nonverbal intelligence, and segmental phonology were also taken. The LI group did not score significantly below the LC group on any PEPS-C task. On 5 of 16 tasks, the LI group scored significantly lower than the CA group. In the LI group, there were just 2 significant correlations between a PEPS-C task and 1 of the nonprosodic measures. The results support the view that intonation is relatively discrete from other levels of speech and language while suggesting some specific areas of possible vulnerability: auditory memory for longer prosodic strings and the of prosody for pragmatic/interactional purposes.
The effect of regional accent on children's processing of speech is a theoretically and practically important aspect of phonological development that has been little researched. 48 children from London, aged four and seven years old, were tested on their ability to repeat and define single words presented in their own accent and in a Glaswegian accent. Results showed that word comprehension was significantly reduced in the Glaswegian condition and that four-year-olds performed less successfully than seven-year-olds. Both groups made similar numbers of lexical misidentifications, but the younger children were more likely to fail to access any word at all. On the repetition task, the younger children showed a different pattern of errors to the older children, their productions being apparently more influenced by the phonetics of the Glaswegian stimuli. It is suggested that such phonetic responses are related to the younger children's failure to map the unfamiliar accent onto their own phonological representations. It is proposed that the lexical misidentifications, common to both age groups, are more likely to be induced by lack of context. The paper concludes with discussion of implications of these findings for our understanding of how children develop the ability to process unfamiliar regional accents.
One aim of current research into talk-in-interaction is to identify the resources that enable recipients to monitor the course of a turn in progress in order to project its upcoming completion. This issue is addressed through analysis of instances of overlapping talk, focusing on their design--that is, their particular prosodic and other linguistic characteristics; their placement--in other words, where precisely they occur in relation to the turn being overlapped; and the subsequent behavior of the coparticipants. Phonetic analysis is combined with interactional techniques developed within Conversation Analysis, to warrant the relevance of categories by reference to the behavior of the participants themselves. As French and Local (1983) found, for an incoming to be treated as turn-competitive, it has to be designed with relatively high pitch and loud volume. These turn-competitive incomings are positioned within the turn in progress, and before the final major accent. By contrast, overlapping incomings positioned after the major accent are not designed as or treated as turn-competitive. On the basis of this analysis, we can define transition relevance place (TRP) as the space between the TRP-projecting accent of the current turn and the onset of the next turn. TRP-projecting accents are identifiable on independent grounds, being phonetically distinct from non-TRP-projecting accents. They thus provide a robust resource for participants to monitor the upcoming completion of the turn.
