This article presents a case study of speech production in a 14-year-old Amharic-speaking boy. The boy had developed secondary macroglossia, related to a disturbance of growth hormones, following a history of normal speech development. Perceptual analysis combined with acoustic analysis and static palatography is used to investigate the specific…

In this article, we discuss the relationship between instrumental and perceptual phonetic analyses. Using data drawn from typical and atypical speech production, we argue that the use of two-tier transcriptions, which can compare and contrast perceptual and instrumental information, is valuable both for our general understanding of the mechanisms…

This study investigated links between working memory and speech processing systems. We used delayed pseudoword repetition in fMRI to investigate the neural correlates of sublexical structure in phonological working memory (pWM). We orthogonally varied the number of syllables and consonant clusters in auditory pseudowords and measured the neural…

Foreign accent syndrome (FAS) is an acquired neurogenic disorder characterized by altered speech that sounds foreign-accented. This study presents a British subject perceived to speak with an Italian (or Greek) accent after a brainstem (pontine) stroke. Native English listeners rated the strength of foreign accent and impairment they perceived in…

This thesis provides a comprehensive account of the intonational phonology of Lakota, an indigenous North American language of the Siouan family. Lakota is predominantly a verb final language, characterized by complex verbal morphology. The phonological description of Lakota intonation and prosody presented here is based on acoustic analysis of…

Many theoretical models of reading assume that different writing systems require different processing assumptions. For example, it is often claimed that print-to-sound mappings in Chinese are not represented or processed sub-lexically. We present a connectionist model that learns the print-to-sound mappings of Chinese characters using the same…

Speakers are faster and more accurate at processing certain sound sequences within their language. Does this reflect the fact that these sequences are frequent or that they are phonetically less complex (e.g., easier to articulate)? It has been difficult to contrast these two factors given their high correlation in natural languages. In this…

Children's early word productions often differ from the target form, sometimes exhibiting vowel lengthening when word-final coda consonants are omitted (e.g., "dog" /d[open o]g/ [arrow right] [d[open o]:]). It has typically been assumed that such lengthening compensates for a missing prosodic unit (a mora). However, this study raises the…

AN ARTICLE ON GRAPHICAL REPRESENTATION OF PERCEIVED PITCH IN SPEECH WAS PRESENTED. THIS ARTICLE, A REPRINT FROM THE PROCEEDINGS OF THE FOURTH INTERNATIONAL CONGRESS OF PHONETIC SCIENCES, PROVIDED A GENERAL DESCRIPTION OF THE METHOD AND INSTRUMENTATION OF GRAPHICALLY DESCRIBING SPEECH INTONATIONS, AND PRESENTED A HISTORICAL AND THEORETICAL…

THIS 2-PART REPORT DEALT WITH THE DEVELOPMENT OF AN INSTRUMENT FOR GRAPHICALLY RECORDING SPEECH INTONATIONS. THE APPENDIXES GAVE DETAILS OF CIRCUITRY AND INSTRUMENTATION FOR THE PITCH MATCHING DEVICE AND THE INTONATION PLAYBACK. (THIS REPORT IS A SUPPLEMENT TO ED 003 881.) (LP)

This paper examines the Spanish phonetic system, as set forth by Navarro Tomas in his "Manual de Pronunciacion Espanola," and discusses the influences exerted by certain sounds over others. (Text is in Spanish.) (CK)

A study of electromyographic (EMG) activity and palatal movement is reported. Motion pictures were taken of the nasal surface of the soft palate and EMG recordings from the levator palatini muscle were obtained. Both were analyzed for the relationship of velar height to EMG strength and time. (SC)

Sentences were read by six informants to determine the presence or absence of /n/ in /nth/ sequences. The sentences contained seven different levels of juncture with /nth/ occurring in word final position, intervocalically, and across word boundaries, among other places. Dental coarticulation was not hindered by most junctures. (SC)

The salience of voiced onset time (VOT) as a voicing cue for initial stop-vowel units is examined. VOT duration was altered. Findings did not indicate that changes in VOT duration altered the perception of voicing. Aspiration more than VOT seems to be more important in the detection of voicing. (SC)
