One of a regular series on the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications, this report covers the period January 1 to March 31, 1985. Studies summarized in the report cover such topics as (1) segmentation of coarticulated speech in perception (2) intrinsic time in…

This study is a detailed analysis of the phonological development of Sylvia, a bilingual child, in her acquisition of American English and Brazilian Portuguese from the age of 1 year, 7 months to 3 years, 8 months. The study is divided into four stages: ages 1.7 - 1.9; 1.9 - 2.1; 2.1 - 2.3; and 2.3 - 2.8. Up to the age of 1.9, the same…

As one of a regular series, this report focuses on the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. Drawn from the period of July 1 to December 31, 1981, the 15 manuscripts cover the following topics: (1) phonetic trading relations and context effects; (2) temporal…

This report is one of a regular series on the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. Drawn from the period of January 1 to March 31, 1980, the 14 manuscripts cover the following topics: (1) acoustics in human communication; (2) motor-sensory feedback formulations;…

GOALS OF A SPEECH IMPROVEMENT PROGRAM FOR THE MENTALLY RETARDED IN WISCONSIN ARE DESCRIBED. THE FOLLOWING VARIOUS ASPECTS OF THE SPEECH PROGRAM ARE PRESENTED--(1) DEVELOPMENT OF A DELAYED SPEECH PROGRAM, (2) USE OF SOCIAL SKILLS FOR SPEECH PRACTICE, (3) REMEDIAL PROGRAM FOR DEFECTIVE ARTICULATION, AND (4) AUDITORY TRAINING. TYPES OF DEFECTS, A…

RESEARCH IS NEEDED TO DETERMINE THE AGE AT WHICH A CHILD WITH A FUNCTIONAL ARTICULATORY DISORDER SHOULD BEGIN THERAPY AND THE FREQUENCY OF THERAPY. THE AUTHORS REJECTED THE SURVEY METHOD BECAUSE OF ITS MANY LIMITATIONS. RESEARCH, USING THE EXPERIMENTAL APPROACH, WAS PLANNED TO SCREEN 30,000 CHILDREN, 724 OF WHOM WOULD BE ASSIGNED TO THERAPY,…

AN AUDIOVISUAL FILM WAS PRODUCED TO HELP RESEARCHERS AND CLINICIANS ESTABLISH THEIR RELIABILITY OF JUDGMENTS OF MISARTICULATIONS IN CHILDREN'S SPEECH. THE FINAL FILM SCRIPT WAS PREPARED AFTER A PRELIMINARY STUDY HAD BEEN EVALUATED BY PANELS OF BOTH TRAINED AND UNTRAINED LISTENERS. SIX CHILDREN, BETWEEN THE AGES OF 6 AND 13, WHOSE MISARTICULATION…

Designed for students of speech pathology and audiology and for practicing clinicians, the text considers the nature of the articulation process, criteria for diagnosis, and classification and etiology of disorders. Also discussed are phonetic characteristics, including phonemic errors and configurational and contextual defects; and functional…

To determine the accuracy with which the 47-item Predictive Screening Test of Articulation (PSTA) is able to identify first grade children who will master their articulation errors without speech therapy by the time they enter third grade, two groups of children were studied who were deficient enough in speech to be enrolled in therapy, but had no…

Preliminary to a survey of a national sample of 40,000 subjects intended to estimate prevalence of speech and hearing disorders in the United States public school population, a mobile unit collected data on a pilot sample of subjects in grades 1 through 12. Speech testing of 6,290 subjects indicated about 85% had articulation which did not deviate…

Communication disorders presentations include the following: expectations of the teacher of the deaf for audiological and psychological services to the young deaf child by Doin E. Hicks; questions and answers on stuttering therapy by Frank J. Falck; the knowledge of words of a deaf child by Toby Silverman; and a comparative study of the modality…

This paper focuses on British English. Such rules as might be devised for specification of segment length would have to take into account, among other factors, the lenis/fortis nature of the segments at syllable margins, degree of stress, the relation between a given syllable and others in the same rhythm group, the same relations within the word,…

Human linguistic ability depends, in part, on the gradual evolution of man's supralaryngeal vocal tract. The anatomic basis of human speech production is the result of a long evolutionary process in which the Darwinian process of natural selection acted to retain mutations. For auditory perception, the listener operates in terms of the acoustic…

The ten papers in this collection are based on presentations given during a colloquium held November 14-15, 1969, at the University of Toronto. The papers, written in either English or French, cover various topics related to prosodic feature analysis in general; several concern the analysis of specific languages. General topics include discussions…

This paper reports on a study in which twenty young adults were tested for their ability to accurately reproduce the articulatory and prosodic features of three non-Indo-European languages in which they had received instruction. The first of two basic goals of this research was to test, at the purely phonetic level, the "critical period for…
