  • 6. Laryngeal Features
    6. Laryngeal features Before you study this chapter, check whether you are familiar with the following terms: allomorph, allophone, aspiration, devoicing, frequency, glottalization, glottal stop, glottis, hiatus, larynx, organs of speech, phoneme, pulmonic egressive airstream, root, sibilant, suffix, syllabic consonant, utterance, vocal cords/folds, voice assimilation, voiced, voiceless, voicing In this chapter we take a look at the articulatory role of the glottis, the vocal cords/folds and all the different phenomena that are related to the operation of the larynx. This includes voicing and voicelessness, (a comparison of English and Hungarian) voice assimilation, devoicing, aspiration and glottalization, and the effect of voicelessness on preceding vowels, Pre-fortis Clipping. Recall from Chapter 1 that the basic mechanism that is used to produce speech sounds in English and Hungarian is a pulmonic egressive airstream mechanism. Having left the lungs, the air continues upward in the windpipe up to the larynx – the front, shield-like part of which is called Adam's apple – then into the pharynx and the supraglottal cavities, the oral and nasal cavities. In the larynx it has to pass between the vocal cords/folds, two bundles of muscle, which may produce numerous different effects. Before discussing these, let us take a look at the structure and parts of the larynx and their different configurations. As it can be seen in the diagram, the larynx consists of some cartilages – one fixed in the front and two movable ones in the back, plus one more on the top not shown in the diagram, the epiglottis, which can close the windpipe, and a circular one serving as the frame for the larynx –, the Laryngeal features vocal cords connecting the cartilages, and the opening between them, the glottis.

This paper is posted at ScholarlyCommons. https://repository.upenn.edu/edissertations/288 For more information, please contact [email protected]. Learning [Voice] Abstract The [voice] distinction between homorganic stops and fricatives is made by a number of acoustic correlates including voicing, segment duration, and preceding vowel duration. The present work looks at [voice] from a number of multidimensional perspectives. This dissertation's focus is a corpus study of the phonetic realization of [voice] in two English-learning infants aged 1;1--3;5. While preceding vowel duration has been studied before in infants, the other correlates of post-vocalic voicing investigated here --- preceding F1, consonant duration, and closure voicing intensity --- had not been measured before in infant speech. The study makes empirical contributions regarding the development of the production of [voice] in infants, not just from a surface- level perspective but also with implications for the phonetics-phonology interface in the adult and developing linguistic systems. Additionally, several methodological contributions will be made in the use of large sized corpora and data modeling techniques. The study revealed that even in infants, F1 at the midpoint of a vowel preceding a voiced consonant was lower by roughly 50 Hz compared to a vowel before a voiceless consonant, which is in line with the effect found in adults.

Using a comprehensive corpus of audio recordings of singing from around the world collected over several decades, the ethnomusicologist Alan Lomax devised the Cantometrics project, the largest comparative study of music, in which 36 performance practice characteristics were rated for each recording. With particular interest in vocal production, we intended to formalise the knowledge of vocal production to enable statistical and computational approaches in the spirit of Cantometrics.

  • Reverse Phonation -Physiologic and Clinical Aspects of This Speech Voice
    Rev Bras Otorrinolaringol 2007;73(2):271-7. REVIEW ARTICLE Reverse phonation - physiologic and clinical aspects of this speech voice therapy modality Leila Susana Finger 1, Carla Aparecida Cielo 2 Keywords: voice, speech, language and hearing sciences. Summary Reverse phonation is the voice production during inspiration, accomplished spontaneously in situations such as when a person sighs. Aim: to do a literature review, describing discoveries related to the use of the reverse phonation in the clinical practice, the anatomy and physiology of its production and its effects in vocal treatments; and moreover, indications and problems of the technique for speech disorders treatment and voice enhancement. Results: there were reports of significant changes in vocal treatment during with the use of reverse phonation: ventricular distention, ventricular folds separation, increase in the fundamental frequency, mucous wave inverse movement; and it also facilitates the dynamic study of the larynx when associated with endoscopy, making it possible to have a better definition of lesion localization in vocal folds superficial lamina propria layers. Conclusion: There are few studies describing larynx behavior during reverse phonation and, for this technique to be used in a more precise and objective way, more studies are necessary in order to prove its effectiveness in practical matters. 1 M.S. in Human Communications Disorders UFSM/RS, Speech and Hearing Therapist, Capes Scholarship holder. 2 PhD in Applied Linguistics - PUC-RS, Speech and Hearing Therapist.

    /VB3 / A/ O,(s0-02 A SURVEY OF THE RESEARCH LITERATURE ON THE FEMALE HIGH VOICE THESIS Presented to the Graduate Council of the University of North Texas in Partial Fulfillment of the Requirements For the Degree of MASTER OF ARTS By Roberta M. Stephen, B. Mus., A. Mus., A.R.C.T. Denton, Texas December, 1988 Stephen, Roberta M., Survey of the Research Literature on the Female High Voice. Master of Arts (Music), December, 1988, 161 pp., 11 tables, 13 illustrations, 1 appendix, bibliography, partially annotated, 136 titles. The location of the available research literature and its relationship to the pedagogy of the female high voice is the subject of this thesis. The nature and pedagogy of the female high voice are described in the first four chapters. The next two chapters discuss maintenance of the voice in conventional and experimental repertoire. Chapter seven is a summary of all the pedagogy. The last chapter is a comparison of the nature and the pedagogy of the female high voice with recommended areas for further research. For instance, more information is needed to understand the acoustic factors of vibrato, singer's formant, and high energy levels in the female high voice. PREFACE The purpose of this thesis is to collect research about the female high voice and to assemble the pedagogy. The science and the pedagogy will be compared to show how the two subjects conform, where there is controversy, and where more research is needed. Information about the female high voice is scattered in various periodicals and books; it is not easily found.
