This paper assesses certain properties of human mental processes by focusing on the tactics utilized in perceiving speech signals. Topics discussed in the paper include the power spectrum approach to fluctuations and noise, with particular reference to biological structures; "l/f-like" fluctuations in speech and music and the functioning of a…

An auditory discrimination procedure was used in this study to attempt to correct the speech problem of a 4-year-old girl. The major characteristic of that speech problem was the consistent use of inappropriate first consonant sounds in some words, like "gog" for "dog." The child was given 25 training sessions and two posttraining sessions. The…

Perception and production data were collected from 28 children, ages 1 year 8 months to 3 years 11 months to test four specific hypotheses on the acquisition of initial fricatives and glides in English, based on the assumptions that perception precedes production and unmarked precedes marked. Perception data were collected by the Shvachkin-Garnica…

Written for students in the fields of speech correction and audiology, the text deals with the following: structures involved in respiration; the skeleton and the processes of inhalation and exhalation; phonation and pitch, the larynx, and esophageal speech; muscles involved in articulation; muscles involved in resonance; and the anatomy of the…

The volume, intended to introduce readers to the problems and therapeutic needs of speech impaired school children, first presents general considerations and background knowledge necessary for basic insights of the classroom teacher and the school speech clinician in relation to the speech handicapped child. Discussed are the classification and…

This study investigated the interrelationship of articulation and receptive and expressive language performance by 306 children in kindergarten and first and second grade in Fort Collins, Colorado, with regard to age, sex, and socioeconomic level. Fifty-one males and 51 females from the sample group were tested on three pairs of tests: the Arizona…

The study determined whether first grade children (nine with good and nine with poor articulation skills) could learn to replicate four positions of lingual-palatal contact with and without topical anesthesia that eliminated touch-pressure sensations. (Author)

A model of phoneme identification is proposed which describes the process by which continuous acoustic featural information about the place of articulation and the voicing of speech sounds is integrated during phoneme identification. (AM)

This paper presents an inventory of the features that are necessary to describe vowel systems in the languages of the world. The relationship between the features and then articulatory and acoustic correlates is explored. (Author/NCR)

Developmental aspects of several temporal parameters in the speech of 2- to 4-year-old English-speaking children were investigated; adults served as a control group. Children seemed to possess timing control systems which are more sophisticated than has previously been suggested. (Author/SW)

Two severely dysarthric speakers--having articulation problems due to lack of muscle control--(17 and 61-years-old) who had previously spelled entire messages on an alphabet board were taught a communication system in which they pointed to the first letter of each word as they spoke. (Author/IM)

Examination of the speech of 33 monolingual Spanish-speaking children found that syllable type affected the correct pronunciation of novel words. The different syllable types comprising the novel words could be hierarchized. Performance on syllable type appeared to be an interaction between the structure of the syllable and phonological processes…

Babbling samples from 11 normally hearing infants and 14 hearing-impaired (HI) subjects, aged 4-39 months, were analyzed. Differences were observed between consonantal phone inventories of hearing-impaired subjects and hearing infants, between inventories of HI subjects with sensori-neural loss and those with conductive loss, and between younger…

Fifty-four audiologists were asked to predict future speech intelligibility in hearing-impaired children based on four pure-tone audiograms. Predictions varied significantly with degree of loss and status of high-frequency hearing. Audiologists with greater clinical experience had less faith in audiograms as predictors of speech skills than had…

Measurement of voice onset time productions associated with three bilabial, three alveolar, and two velar stops in 3- to 7-year-olds and adults indicated that, by five years of age, children have acquired all voicing contrasts; however, not all sounds are produced in an adult-like manner.
