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…

Smith (1973), Stampe (1972), and Braine (1973) believe that by the time the child speaks his perception is well-developed, and that any discrepancy between child forms and adult forms are due to organizational and production difficulties. Other linguists believe immature perception determines the form of child speech. This paper suggests that…

During the past reporting period the curriculum materials for the mentally retarded section of Project MORE (Mediated Operational Research for Education) has continued its work on development and dissemination. Technology on the programs is advancing to a degree where production on several of the programs is imminent. The major activities of the…

This volume is devoted to phonetics and phonology. It consists of the following papers: (1) "Generative Phonology, Dependency Phonology and Southern French," by J. Durand, which discusses aspects of a regional pronunciation of French, the status of syllables in generative phonology, and concepts of dependency phonology; (2) "On the…

Examines one aspect of second-language syllable structure, syllable-final clusters, in the English of a Vietnamese first-language speaker. The article shows that errors apparently not due to native-language influence can be so attributed using the cluster reduction rule, that the position of a reduced consonant can be predicted based on…

A test of the ability of adult Japanese and Korean students to perceive correct and misarticulated /r/ involved tape recordings of native English speakers and the students themselves. Comparison of the results "subjects made more errors perceiving their own speech" with similar research on first- and second-language acquisition has pedagogical…

This study investigated the acquisition of speaking skills in an online distance education course of 19 first semester Spanish learners. The possibility of oral development in a strictly online course was examined based on students' pronunciation production in two types of recorded speaking activities and in two real-time conversations. Students…

One of a series of quarterly reports, this publication contains 14 articles which report the status and progress of studies on the nature of speech, instruments for its investigation, and practical applications. Articles in the publication are: "Some Assumptions about Speech and How They Changed" (Alvin M. Liberman); "On the…

Research reports on the nature of speech, instrumentation for its investigation, and practical applications of research are provided in this status report covering the period of April 1 through June 30, 1982. The 13 reports deal with the following topics: (1) the functional significance of physiological tremor, (2) differences between experienced…

The purpose of the research was to develop an articulation test for Spanish-speakers and to field-test the instrument in both a monolingual Spanish-speaking environment and a bilingual Spanish/English environment. Such a test is needed because there has been little available to enable the diagnostician, whose clientele includes Spanish-speakers,…

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…

Spanish-speaking children of Mexican descent living in California were tested on the acquisition of 18 Spanish consonants. The 120 subjects (aged 3 to 5:7 years) were equally divided into eight age groups, and the median ages (50%) and upper age limits (90%) of customary production of each consonant were determined. (Author/JDD)

Examines the effects of vowel height and place of articulation in interlanguage devoicing patterns of final voiced stop consonants (b, d, g) in words such as "cab,""bad,""bag" in the acquisition of English as a foreign language by Mandarin, Japanese, and Portuguese speakers. Results display a combinatory effect of…

The speech production of a prelingually deafened adult male was examined at 4 intervals: 1 week and again at 9 months postimplant with a single-channel cochlear implant, 14 months later with a nonfunctioning device, and 1 year following implantation with a multichannel device. Consonant accuracy and vowel accuracy changed little across conditions.…

The speech-production skills of 38 school-aged siblings and 94 parents of children with phonology disorders were assessed by administering tasks involving the repetition of multisyllabic real and nonsense words, and "difficult-to-articulate" phrases and sentences. Results demonstrated that speech production, as measured by these tasks,…
