This nasalization is known to lead to changes in perceived vowel quality. The goal of this project is to verify if it is beneficial to first recognize nasalization in vowels and treat the three groups of vowels (those occurring before nasal consonants, those occurring after nasal consonants, and the oral vowels which are vowels that are not adjacent to nasal consonants) separately rather than collectively for recognizing the vowel identities. The standard Mel-Frequency Cepstral Coefficients (MFCCs) and the Hidden Markov Model (HMM) paradigm have been used for this purpose. The results show that when the system is trained on vowels in general, the recognition of nasalized vowels is 17% below that of oral vowels. -
Nasal Assimilation in Quranic Recitation Table of Contents
EmanQuotah Linguistics Senior Paper Hadass Sheffer, Advisor Swarthmore College December 9, 1994 Nasal Assimilation in Quranic Recitation Table of Contents Introduction 1 TheQuran 3 Recitation and Tajwi:d 7 Nasal Assimilation in Quranic Recitation 10 Arabic geminates 12 Nasal assimilation rules 15 Blocking of assimilation by pauses 24 Conclusion 26 Bibliography Grateful acknowledgements to my father, my mother and my brothers, and to Hadass Sheffer and Donna Jo Napoli. Introduction This paper is concerned with the analysis of certain rules governing nasality and nasal assimilation during recitation of the holy Quran. I These rules are a subset of tajwi:d, a set of rules governing the correct prescribed recitation and pronunciation of the Islamic scriptures. The first part of the paper will describe the historical and cultural importance of the Quran and tajwi:d, with the proposition that a tension or conflict between the necessity for clarity and enunciation and the desire for beautification of the divine words of God is the driving force behind tajwi:d's importance. Though the rules are functional rather than "natural," these prescriptive rules can be integrated into a study lexical phonology and feature geometry, as discussed in the second section, since prescriptive rules must work within those rules set by the language's grammar. Muslims consider the Quran a divine and holy text, untampered with and unchangeable by humankind. Western scholars have attempted to identify it as the writings of the Prophet Muhammad, a humanly written text like any other. Viewing the holy Quran in this way ignores the religious, social and linguistic implications of its perceived unchangeability, and does disservice to the beliefs of many Muslims. -

Ohala, Chair Understanding the relationship of aerodynamic laws to the unique geometry of the hu- man vocal tract allows us to make phonological and typological predictions about speech sounds typified by particular aerodynamic regimes. For example, some have argued that the realization of nasalized fricatives is improbable because fricatives and nasals have an- tagonistic aerodynamic specifications. Fricatives require high pressure behind the suprala- ryngeal constriction as a precondition for high particle velocity. Nasalization, on the other hand, vents back pressure by allowing air to escape through the velopharyngeal orifice. This implies that an open velopharyngeal port will reduce oral particle velocity, thereby potentially extinguishing frication. By using a mechanical model of the vocal tract and spoken fricatives that have undergone coarticulatory nasalization, it is shown that nasal- ization must alter the spectral characteristics of fricatives, e.g. -
Part 1: Introduction to The
PREVIEW OF THE IPA HANDBOOK Handbook of the International Phonetic Association: A guide to the use of the International Phonetic Alphabet PARTI Introduction to the IPA 1. What is the International Phonetic Alphabet? The aim of the International Phonetic Association is to promote the scientific study of phonetics and the various practical applications of that science. For both these it is necessary to have a consistent way of representing the sounds of language in written form. From its foundation in 1886 the Association has been concerned to develop a system of notation which would be convenient to use, but comprehensive enough to cope with the wide variety of sounds found in the languages of the world; and to encourage the use of thjs notation as widely as possible among those concerned with language. The system is generally known as the International Phonetic Alphabet. Both the Association and its Alphabet are widely referred to by the abbreviation IPA, but here 'IPA' will be used only for the Alphabet. The IPA is based on the Roman alphabet, which has the advantage of being widely familiar, but also includes letters and additional symbols from a variety of other sources. These additions are necessary because the variety of sounds in languages is much greater than the number of letters in the Roman alphabet. The use of sequences of phonetic symbols to represent speech is known as transcription. The IPA can be used for many different purposes. For instance, it can be used as a way to show pronunciation in a dictionary, to record a language in linguistic fieldwork, to form the basis of a writing system for a language, or to annotate acoustic and other displays in the analysis of speech. -

The Taittirtyaprtiakhya As on Antjsvara
THE TAITTIRTYAPRTIAKHYA AS 密 ON ANTJSVARA 教 文 Nobuhiko Kobayasi 化 A The dot at the left upper corner of an Indian letter1) represents a nasal element called anusvara (that which follows a vowel).2) The descriptions of anusvara as found in the works of ancient Indian phoneticians3) are so inconsistent and confusing that modern Sanskrit scholars are still confused. Some represented by the author of the Atharvavedapratiaakhya hold that it is a pure nasalized vowel,4) and others represented by the author of the RkpratiS'akhya say that it is either a vowel and a consonant.5) There is also another school, according to which it is a pure consonant.6) B An Indo-aryan syllable (aksara)7) is heavy (guru) or light (laghu). It is heavy, when the vowel is long8) or followed by a conjunction of con- sonants,9) and it is light when the vowel is short or not followed by a con- junction of consonants.10) An important feature of the phonetic element called anusvara is that it affects meter. According to the Taittiriyapratisakhya (TP), a letter with the anusvara sign represents a metrically long syllable." On the basis of this, description of the TP, Whitney adopts the view that anusvara is a lengthened nasal vowel.12) He seeks support for his interpretation from the fact that the anusvara sign is written over the vowel -112- of the first syllable.131 So the phonetic value of vamsa is interpreted as [Qa:sa]. This interpretation seems to be supported by such Hindi develop- THE TAITTIRIYAPRATISAKHYA ON ANUSVARA ment of anusvara as in vamsa>bas. -
Perception of Brazilian Portuguese Nasal Vowels by Danish Listeners
121 Perception of Brazilian Portuguese Nasal Vowels by Danish Listeners Denise Cristina Kluge Federal University of Rio de Janeiro (UFRJ) Abstract The word-fi nal nasals /m/ and /n/ have different patterns of phonetic realizations across languages, whereas they are distinctively pronounced in English and Danish, in Brazilian Portuguese (BP) they are not fully realized and the preceding vowel is nasalized. Bearing in mind this difference, the main objective of this study was to investigate the perception of BP nasal vowels by Danish learners of BP. Two discrimination and two identifi cation tests were used and taken by two groups composed of ten Danish learners of English, as a reference for comparison, and ten Danish learners of BP. General results showed both groups had similar diffi culties in both discrimination tests. It was less diffi cult for the Danish learners of BP to identify the BP native-like pronunciation when presented in contrast to a non-native-like pronunciation. 1. Introduction Many studies concerning the perception of second language (L2) sounds have discussed the infl uence of the native language (L1) on accurate perception of the L2 (Flege, 1993, 1995; Wode, 1995; Best, 1995; Kuhl & Iverson, 1995). Moreover, some L2 speech models have discussed the role of accurate perception on accurate production (Flege, 1995; Best, 1995; Escudero, 2005; Best & Tyler, 2007). According to some studies (Schmidt, 1996; Harnsberger, 2001; Best, McRoberts & Goodell, 2001; Best & Tyler, 2007), it is usually believed that, at least in initial stages of L2 learning, adults are language-specifi c perceivers and that they perceive L2 segments through the fi lter of their L1 sound system. -
On the Anatomy of a Chain Shift1 DANIEL A
J. Linguistics, Page 1 of 25. f Cambridge University Press 2010 doi:10.1017/S0022226710000368 On the anatomy of a chain shift1 DANIEL A. DINNSEN, CHRISTOPHER R. GREEN, JUDITH A. GIERUT & MICHELE L. MORRISETTE Indiana University (Received 4 September 2009; revised 28 April 2010) Phonological chain shifts have been the focus of many theoretical, developmental, and clinical concerns. This paper considers an overlooked property of the problem by focusing on the typological properties of the widely attested ‘s>h>f’ chain shift involving the processes of Labialization and Dentalization in early phonological development. Findings are reported from a cross-sectional study of 234 children (ages 3 years; 0 months–7;9) with functional (nonorganic) phonological delays. The results reveal some unexpected gaps in the predicted interactions of these processes and are brought to bear on the evaluation of recent optimality theoretic proposals for the characterization of phonological interactions. A developmental modification to the theory is proposed that has the desired effect of precluding certain early-stage grammars. The proposal is further evaluated against the facts of another widely cited developmental chain shift known as the ‘puzzle>puddle>pickle’ problem (Smith 1973). 1. I NTRODUCTION A common phenomenon in both first- and second-language acquisition and in fully-developed languages is for phonological processes to participate in a chain shift (e.g. Moreton & Smolensky 2002, Jesney 2005, Dinnsen 2008b). Chain shifts typically involve two phonological processes that interact in such a way that they result in an opaque generalization (i.e. one that is not surface-true). This phenomenon has generated much discussion and contro- versy in the theoretical, developmental, and clinical literature over the years and has raised questions about the very nature of chain shifts. -

The Morphophonemics of Vowel Compensatory Lengthening in Ekegusii
International Journal of Education and Research Vol. 1 No. 9 September 2013 The Morphophonemics of Vowel Compensatory Lengthening in Ekegusii Samwel Komenda a, Geoffrey M. Maroko b*, Ruth W. Ndung’u c Kenyatta University, P.O Box 43844 – 00100, Nairobi, Kenya Corresponding author Email: [email protected] Tel: 0 712 660 638 ________________________________________________________________________________________________________ Abstract Literature shows that not much is known about the prosodic systems in Ekegusii, a Bantu language spoken by about 2.2 million people in south western Kenya. This paper presents an analysis of vowel compensatory lengthening in Ekegusii. Synchronic evidence for hiatus resolution strategies is provided in order to describe the vowels that are lengthened compensatorily and determine the morphological processes that trigger compensatory lengthening in Ekegusii. Guided by native speaker intuition and triangulation by other native speakers, data in the form of nominals and verbals were elicited from four Ekegusii texts and qualitatively analysed for emerging patterns. Findings revealed that all the seven basic Ekegusii vowels undergo compensatory lengthening when their phonetic environments are altered. Vowel compensatory lengthening is brought out as a surface realisation of the interaction of morphemes through the morphological process of prefixation. The lengthening is further seen as a conspiracy to eliminate ill-formed sequences created by prefixation. The height of the first vowel and whether it is followed -
Toward a Unified Theory of Chain Shifting
OUP UNCORRECTED PROOF – FIRST-PROOF, 04/29/12, NEWGEN !"#$%&' () TOWARD A UNIFIED THEORY OF CHAIN SHIFTING *#'+, -. ./,0/, !. I"#$%&'(#)%" Chain shifts play a major role in understanding the phonological history of English—from the prehistoric chain shift of Grimm’s Law that separates the Germanic languages from the rest of Indo-European, to the Great Vowel Shift that is often taken to define the boundary between Middle English and Early Modern English, to the ongoing chain shifts in Present-Day English that are used to estab- lish the geographical boundaries between dialect regions. A chain shift may be defined as a set of phonetic changes affecting a group of phonemes so that as one phoneme moves in phonetic space, another phoneme moves toward the phonetic position the first is abandoning; a third may move toward the original position of the second, and (perhaps) so on. Martinet (12(3) introduced the argument that chain shifts are caused by a need for phonemes to maintain margins of security between each other—so if a phoneme has more phonetic space on one side of it than on others, random phonetic variation will cause it to move toward the free space but not back toward the margins of security of phonemes on the other side. Labov (3414: chapter 5) gives a lucid exposition of the cognitive and phonetic argu- ments underlying this account of chain shifting. Despite their value as a descriptive device for the history of English, however, the ontological status of chain shifts themselves is a matter of some doubt.
