Argues that knowing how infants process speech is a prerequisite to any definition of linguistic experience and therefore, the discrimination paradigm does not provide a test for the effect of experience on infants' speech discrimination. Outlines conditions to be met in order to conclude an effect of experience. (EKN)

THE FOUR STUDIES INCORPORATED IN THIS PROGRESS REPORT ATTEMPTED TO ANALYZE STABILIZED LANGUAGE PROCESSES AND TO EXAMINE THE COMPONENTS OF LANGUAGE PERFORMANCE, RANGING FROM SYSTEMATIC PHONETICS TO LOGICAL DISCOURSE. THE FIRST STUDY REPORTED WORK ON HUMAN AUDITORY SENSITIVITY AS A FUNCTION OF FREQUENCY AND INTENSITY. THE NEXT TWO STUDIES WERE…

Two studies of adult aphasia, focusing on phonological disturbances, are presented. In the first study, subjects were 15 adults wit moderate aphasia and five age-matched controls. A variety of speech production and speech perception tests were administered, including tests of syllable discrimination, auditive word-picture matching, articulation,…

THIS REPORT DESCRIBES IN DETAIL FIVE RELATED EXPERIMENTS THAT WERE CONDUCTED IN AREAS PERTAINING TO THE TEACHING OF FRENCH PRONUNCIATION TO NATIVE SPEAKERS OF AMERICAN ENGLISH. THE FIRST TWO EXPERIMENTS SOUGHT TO DETERMINE THE RELATIVE ACCEPTABILITY OF 38 ENGLISH PHONEMES TO NATIVE FRENCH LISTENERS AT EACH OF TWO ACCEPTABILITY LEVELS--PHONEMIC AND…

A review of research leads to the proposal that infants' perception of "fragile" contrasts is lost due to their lack of exposure to particular sounds. Perception of "robust" contrasts is lost around the onset of formal language training due to children's lack of experience with phonologically irrelevant sounds. (Author/CB)

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,…

Parallels between sign stimuli and speech cues suggest some interesting speculations about the origins of language. Speech cues may belong to the class of human sign stimuli which, as in animal behavior, may be the product of an innate releasing mechanism. Prelinguistic speech for man may have functioned as a social-releaser system. Human language…

Local increases in fundamental frequency (Fo) and large integrals of energy in the syllabic nucleus are known to be among the best acoustical correlates of stress. Major syntactic constituents have been shown to have archetype rapid-rise-then-gradual-fall Fo contours, with the rise into the maximum Fo often associated with the first stressed…

Acoustical correlates of stress can only be evaluated in comparison with some "standard" specifying which syllables are actually stressed. The Standard should be consistent from time to time, and largely independent of talker and listener idiosyncrasies. Three phonetically-trained subjects listened to repeatedly spoken texts and spontaneous…
