It is often thought that the ability to use prosodic features accurately is mastered in early childhood. However, research to date has produced conflicting evidence, notably about the development of children’s ability to mark prosodic boundaries. This paper investigates (i) whether, by the age of eight, children use temporal boundary features in their speech in a systematic way, and (ii) to what extent adult listeners are able to interpret their production accurately and unambiguously. The material consists of minimal pairs of utterances: one utterance includes a compound noun, in which there is no prosodic boundary after the first noun, e.g. ‘coffee-cake and tea’, while the other utterance includes simple nouns, separated by a prosodic boundary, e.g. ‘coffee, cake and tea’. Ten eight-year-old children took part, and their productions were rated by 23 adult listeners. Two phonetic exponents of prosodic boundaries were analysed: pause duration and phrase-final lengthening. The result...

ABSTRACT Α psycholinguistic framework for speech processing was adopted to investigate the development of phonological and morphological skills in children learning Greek. It was investigated whether morphological items pose specific challenges in terms of speech processing. Two groups of typically developing children aged 3.0–3.5 years (N = 16) and 4.6–5.0 years (N = 22), respectively, were assessed longitudinally at three assessment points 6 months apart. A range of phonologically based and morphologically based experimental speech processing tasks was administered to address the research question, along with language comprehension and production assessments to ensure that the children were developmentally typical. Stimuli of minimal phonological difference and minimal morphological difference, respectively, were used. Phonologically based experimental stimuli were used to assess performance differences across properties such as voicing, manner and place of articulation, in addition to variation in phonotactic structure. Morphologically based experimental stimuli were used to assess the impact of characteristics such as verb tense and possessive pronouns. Stimuli were incorporated into tasks of real word and nonword auditory discrimination and repetition, to assess input and output processing. Items were matched across tasks so that comparisons could be made. On most of the matched tasks, there was no significant difference in performance accuracy between morphological and phonological conditions. Moreover, a significant relationship was found between domains. It is suggested that morphological items, compared to phonological items, do not pose specific challenges in terms of speech processing. The clinical implications of these findings for assessment and intervention are discussed.

Standardised tests of whole-word accuracy are popular in the speech pathology and developmental psychology literature as measures of children's speech performance. However, they may not be sensitive enough to measure changes in speech output in children with severe and persisting speech difficulties (SPSD). To identify the best ways of doing this, we compared a range of commonly used procedures for perceptual phonological and phonetic analysis of developmental speech difficulties. Data are drawn from four children with SPSD, recorded at 4 years and again at 6 years old performing naming and repetition tasks. Measures of speech output included percentage of whole words correct (PWC), percentage of consonants correct (PCC), proportion of whole-word proximity (PWP), phonological pattern (process) analysis and phonetic inventory analysis. Results indicate that PWC captures change only when identical stimuli are used across time points. PCC is a more robust indicator of change, being less affected by the choice of stimuli. PWP also captures change across time and tasks, while appearing to be more sensitive than PCC to psycholinguistic variables. PCC and PWP are thus both potentially useful tools for evaluating speech outcomes.

The development of phonological awareness (PA), the ability to reflect on the sound structure of words independent of their meaning, has been extensively explored in English-speaking children. However, this is not the case for other languages. The aim of this study was to develop a comprehensive PA test battery for German-speaking preschool children, considering psycholinguistic, linguistic, and cognitive aspects and to carry out analyses of its psychometric properties. Cross-sectional data from a sample of 55 children (CA 4;0-6;11 years) were collected. Preliminary findings confirm validity and reliability of the test battery, and support previous findings that PA develops from larger to smaller linguistic units. Phoneme-level tasks were consistently associated with letter knowledge. The new instrument is a promising tool for basic research (e.g. cross-linguistic comparisons of PA development) as well as for clinical and educational practice (e.g. planning speech and language therapy or literacy-oriented intervention).

The role of prosodic features in the management of turntaking is investigated in interactions between an Englishlearning boy aged 19-21 months and his mother. The child is able to project turn continuation and completion prosodically. However, on occasions of overlapping talk, it is the mother who works to resolve the situation. She does this by differential deployment of clusters of temporal and prosodic behaviours, characterised as ‘curtail and recycle’ vs. ‘persist to completion’. These two embody different stances by the mother towards the status of the child’s overlapped turn in relation to the unfolding talk.

This paper investigates the prosodic features that speakers use to compete for the turn when they talk simultaneously. Most previous research has focused on F0 and energy variation as resources for turn competition; here, we investigate the relevance of speech rate, pausing and the duration of in-overlap talk. These features are extracted from a set of overlaps drawn from the ICSI Meetings Corpus, and used to derive decision trees that classify overlapping talk as competitive or non-competitive. The decision trees show that both pausing and the duration of the in-overlap speech are significantly related to turn competition for both overlappers and overlappees. Additionally, speech rate is used by overlappees to return competition upon a turn competitive incoming. These findings partially support and extend the observations made in previous studies within the framework of conversation analysis and interactional phonetics.

Prosodic constructions used to compete for the speaking turn in conversation have been widely studied (French & Local (1983), Kurtic et al. (2013)). Usually, turn competition arises in overlapping talk between at least two speakers. Coordination between participants in their prosodic design of talk (Szczepek-Reed, 2006) and social action (Gorisch et al. 2012), as well as entrainment in more general terms (Levitan et al. 2011), is well established in the literature. Nevertheless, previous studies on turn competition and overlap do not investigate the prosodic design of turn competitive incomings in reference to the orientation of the speakers to each other. Rather, they assume that prosodic constructions are used for turn competition regardless of the co-participants’ design of the turn. In this paper, we ask whether the prosodic design of turn competitive talk is co-constructed between two participants talking in overlap. More specifically, we investigate whether the prosodic design...

Les etudes de la prosodie dans les interactions conversationnelles ont mis en evidence la facon complexe et subtile dont font preuve les locuteurs dans l'utilisation des traits prosodiques pour negocier lors des interactions quotidiennes. Dans les analyses developpementales et cliniques, la question est de savoir comment les enfants apprennent a gerer (ou n'apprennent pas a le faire) la facon de maintenir l'interaction sociale, malgre des limitations prosodiques ou d'un autre ordre. La premiere partie de l'article est centree sur le developpement typique: la facon dont un enfant entre 19-21 mois et la personne qui s'en occupe s'orientent vers un systeme de signalisation par la prosodie est decrite, systeme permettant a l'enfant de construire des tours de parole etendus.

In this paper we present a corpus of audio and video recordings of spontaneous, face-to-face multi-party conversation in two languages. Freely available high quality recordings of mundane, non-institutional, multi-party talk are still sparse, and this corpus aims to contribute valuable data suitable for study of multiple aspects of spoken interaction. In particular, it constitutes a unique resource for spoken Bosnian Serbo-Croatian (BSC), an under-resourced language with no spoken resources available at present. The corpus consists of just over 3 hours of free conversation in each of the target languages, BSC and British English (BE). The audio recordings have been made on separate channels using head-set microphones, as well as using a microphone array, containing 8 omni-directional microphones. The data has been segmented and transcribed using segmentation notions and transcription conventions developed from those of the conversation analysis research tradition. Furthermore, the t...

ABSTRACT Rhyme ability is an important measure of a child's phonological processing skills. Rhyme tasks can be used to investigate these skills in children with speech, language and literacy problems. However, variable norms have been reported in the literature. This study investigates rhyme skills in 100 normally-developing children in the age-range of 3-7 years. A series of related rhyme tasks were designed to tap different levels of input, representation and output phonological processing skills. The tasks include nursery rhyme knowledge, rhyme production, rhyme judgement and rhyme detection. The same or matched stimuli are used across tasks to allow comparisons to be made. Real and non-words are used and presentation is in both the auditory and visual modalities. The results are analyzed quantitively and qualitatively and are interpreted within a psycholinguistic framework. The findings are discussed with reference to normal and atypical development of rhyme skills, and some clinical implications are drawn.

ABSTRACT Sue Peppé's article (2009) surveys key issues relevant to the clinical assessment and management of prosodic aspects of spoken communication. In the first part of this commentary, we demonstrate one approach to assessment, which involves close analysis of the use of prosody in spontaneous talk-in-interaction. This approach derives from one pioneered by David Crystal, supplemented by techniques drawn from Conversation Analysis which allow for greater precision and objectivity in the characterization of prosodic meaning. The type of analysis is illustrated with data from an 11-year-old boy with severe autism. In the second part, the same data are used to illustrate how phonetic, phonological and interactional notations can be combined in a single transcription. It is suggested that this notational system can be of value in highlighting how mutual understanding can be achieved through prosody, even when one participant is not using a recognized prosodic system. The two parts of the commentary are linked by the notion that a prime function of prosodic features is to contribute to the management of turn-taking.
