This paper examines the validity of the concept of linguistic units in a theory of speech production. Substantiating data are drawn from the study of the speech production process itself. Secondarily, an attempt is made to reconcile the postulation of linguistic units in speech production theory with their apparent absence in the speech signal.…

This report is one of a regular series on the status and progress of speech research. The 16 manuscript topics are: the relative accessibility of semantic and deep structure syntactic concepts, some relationships between articulation and perception, reflex activation of laryngeal muscles by sudden induced subglottal pressure changes, dynamic…

This paper deals with problems concerning the nature of the input to a phonetic processor. Several assumptions provide the basis for consideration of the problem. There is a phonological level of processing which reflects the sound structure of the language; the rules associated with it are not affected by variables associated either with the…

The comprehensibility of materials compressed and then expanded by means of an electromechanical process was tested with 280 Army inductees divided into groups of high and low mental aptitude. Three short listening selections relating to military activities were subjected to compression and compression-expansion to produce seven versions. Data…

This report is one of a regular series on the status and progress of speech research. Manuscript topics are categories and context in the perception of isolated steady-state vowels; tongue position in rounded and unrounded front vowel pairs; the reading behavior of dyslexics: is there a distinctive pattern?; articulatory units: segments or…

This report describes in two volumes the proceedings of a conference on the perception of language held at the University of Pittsburgh in January, 1968. The objectives of the conference, to present the particular research interests of the participants and to attempt to find points of concurrence in thinking through discussion of the conference…

This document contains 21 reports on speech research relating to the following areas: phonology, speech development, speech perception, phonetics, short-term memory of tactile stimuli, reading, linguistic and paralinguistic interchange, computer processing of EMG (electromyographic) signals, pitch determination by adaptive autocorrelation method,…

Paraphrase, as it reflects the processes of remembering rather than those of forgetting, implies that language is best transmitted in one form and stored in another. The dual representation of linguistic information that is implied by paraphrase is important for storing information that has been received and for transmitting information that has…

THIS REPORT DISCUSSES THE RESULTS OF A TWO-YEAR DEMONSTRATION PROJECT IN WHICH SCHOOL AGE CHILDREN WITH FUNCTIONAL ARTICULATION DISORDERS ROUTINELY RECEIVED AUDITORY DISCRIMINATION TRAINING BY PROGRAMED INSTRUCTION IN AN ACTUAL CLINICAL SETTING. AUDITORY DISCRIMINATION PROGRAMS FOR THE TEN MOST FREQUENTLY MISARTICULATED ENGLISH CONSONANTS WERE…

This book seeks to point out the difficulties which remain in phonetic theory because of a legacy from prephonemic days when phonetics and phonemics were one. Sounds were shown to have been chosen for description because of their use in speech rather than because of their articulatory or acoustic nature; many sounds were ignored because they were…

This book, uniting the material from numerous lectures on communication theory, is designed to serve as the introduction to a series entitled "Studies in Communication," which will appear during the next few years. It is not intended for the expert in each of the many fields related to human communication, but, rather, it is designed for the…

This report on speech research contains papers describing experiments involving both information processing and speech production. The papers concerned with information processing cover such topics as peripheral and central processes in vision, separate speech and nonspeech processing in dichotic listening, and dichotic fusion along an acoustic…

This is one of a series of reports intended to make the results of research available and to serve as progress reports. The following abstracts are included: (1) "Learning the Phonetic Cues to the Voiced-Voiceless Distinction: Preliminary Study of Four American English Speaking Children," Mel Greenlee; (2) "Learning the Phonetic Cues to the…

THE GROWTH, DEVELOPMENT, AND ABNORMALITIES OF SPEECH IN CHILDHOOD ARE DESCRIBED IN THIS TEXT DESIGNED FOR PEDIATRICIANS, PSYCHOLOGISTS, EDUCATORS, MEDICAL STUDENTS, THERAPISTS, PATHOLOGISTS, AND PARENTS. THE NORMAL DEVELOPMENT OF SPEECH AND LANGUAGE IS DISCUSSED, INCLUDING THEORIES ON THE ORIGIN OF SPEECH IN MAN AND FACTORS INFLUENCING THE NORMAL…

This guide for a basic high school speech course is intented to develop the student's sense of responsibility for words and actions, his skills in the use of the voice and bodily actions, his poise and self-confidence, and his appreciation and understanding of other people's ideas. The nine units included in the guide are concerned with listening,…
