Fifteen caregivers each glossed a simultaneously videotaped and audiotaped sample of their child with speech delay engaged in conversation with a clinician. One of the authors generated a reference gloss for each sample, aided by (a) prior knowledge of the child’s speech-language status and error patterns, (b) glosses from the child’s clinician and the child’s caregiver, (c) unlimited replays of the taped sample, and (d) the information gained from completing a narrow phonetic transcription of the sample. Caregivers glossed an average of 78 of the utterances and 81 of the words. A comparison of their glosses to the reference glosses suggested that they accurately understood an average of 58 of the utterances and 73 of the words. Discussion considers the implications of such findings for methodological and theoretical issues underlying children’s moment-to-moment intelligibility breakdowns during speech-language processing.

Speech Sound Development

Prior articles in this series provide a descriptive profile of 178 children with developmental phonological disorders (Shriberg & Kwiatkowski, 1994) and predictive correlates of short-term speech-sound normalization in 54 children (Shriberg, Kwiatkowski, & Gruber, 1994). The present article reports findings from a study of 10 children with developmental phonological disorders whose progress was followed at least once yearly for 7 years. Analyses characterize the sequence, rates, and error patterns of long-term speech-sound normalization in relation to developmental perspectives on the nature of children’s phonological disorders. Findings are interpreted to support the hypothesis of a critical period for speech-sound development, with long-term normalization of significant speech delay reaching a chronological age boundary at approximately 8.5 years.

Frequency Feature

This study examined the interaction of ambient frequency and feature complexity in the diphthong errors produced by Cantonese-speaking children with phonological disorders. A total of 611 diphthongs produced by 13 Cantonese-speaking children with speech disorders were subjected to perceptual analysis. The percentage accuracy of production and error patterns was examined. Perceptual analysis showed that /i/ and /ui/ were most frequently in error, whereas /ei/, /ou/, and /u/ were least frequently in error. Diphthong errors (usually diphthong reduction) arise as a function of both ambient frequency and feature complexity. The combination of ambient frequency and feature complexity yields a complexity metric reflecting accuracy of production. Treatment guidelines include consideration of three basic factors: ambient frequency, feature complexity, and error patterns.

Cluster Reduction

This paper presents a case study of a Jordanian child with phonological speech disorders. It seeks to investigate functional phonological disorders and their treatment among Jordanian children within an Optimality Theoretic (OT) perspective. It aims to provide treatment for children’s speech errors within a constraint-based system. The analysis of the data identifies seven error patterns in the child’s productions, namely: fronting, lateralization, stopping, devoicing, de-emphasization, syllable deletion and cluster reduction. Furthermore, OT is employed at the end of the study as a guideline to select the priority of treatment goals by demoting responsible markedness constraints below faithfulness constraints.

Interest in the nature, development and use of ontologies is becoming increasingly widespread. Since the early nineties, numerous workshops have been held. Representatives from historically separate disciplines concerned with philosophical issues, knowledge acquisition and representation, planning, process management, database schema integration, natural language processing and enterprise modelling, came together to identify a common core of issues of interest. There was highly varied and inconsistent usage of a wide variety of terms, most notably, “ontology”, rendering cross-discipline communication difficult. However, progress was made toward understanding the commonality among the disciplines. Subsequent workshops addressed various aspects of the field, including theoretical issues, methodologies for building ontologies, as well as specific applications in government and industry.

Over Time

This tutorial presents an introduction to the contemporary linguistic framework known as optimality theory (OT). The basic assumptions of this constraint-based theory as a general model of grammar are first outlined, with formal notation being defined and illustrated. Concepts unique to the theory, including “emergence of the unmarked,” are also described. OT is then examined more specifically within the context of phonological acquisition. The theory is applied in descriptions of children's common error patterns, observed inter- and intrachild variation, and productive change over time. The particular error patterns of fronting, stopping, final-consonant deletion, and cluster simplification are considered from an OT perspective. The discussion concludes with potential clinical applications and extensions of the theory to the diagnosis and treatment of children with functional phonological disorders.

Theoretical Issues

This article shows how a high-quality filtering architecture for targetted documents can be achieved by adapting the intex system to the domain (i.e. ‘economic intelligence’), when expressed in finite state automata filters. A push system named corail (‘request composition by linguistic intelligent agents’) is described, developed by a consortium comprising Thomson-CSF Corporate Laboratory (senior partner), Informatique-CDC, the University of Paris X/CRIS, and the ladl. Both practical and theoretical issues regarding the use of finite state automata are discussed, as for example the notion of the ‘automaton classes’ which are to be used as a paraphrasing agent in the process of document filtering. This project can be considered as an example of how linguistics and computer science can interact in anatural language processing task to meet high-quality standards, namely avoiding noise and reducing silence, thus offering an alternative solution to traditional push systems based on simple keyword-matching. A prototype of the corail system is now operational at Thomson-CSF Central Laboratory and Informatique-CDC.
