  • CONNECTED SPEECH IPA Symbols Represent the Correct Pronunciation
    CONNECTED SPEECH IPA symbols represent the correct pronunciation of single words or segments of speech. However, we use single words or segments in isolation only occasionally. E.g., we can say “ah!” /ɑː/ to express surprise, or “sh!” /ʃ/ if we want to tell somebody to be quiet. Most commonly we use segments of speech or single words in a sequence, to form phrases or sentences. The sound “ah!” /ɑː/, for example, is likely to be found in whole sentences, to express: - surprise (“Ah, there you are!”) - pleasure (“Ah, this coffee is good.”) - admiration or sympathy (“Ah well, better luck next time.”) - when you disagree with somebody (“Ah, but that may not be true.”) In fact, we commonly use language in continuous, connected speech. Connected speech means speech produced without pauses. A consequence of connected speech is that single segments of speech are influenced by neighbouring segments (that is to say, speech sounds that come before and after them), and may slightly change their place or manner of articulation, or may sometimes totally disappear. Therefore the pronunciation of an isolated word may be different from the pronunciation of the same word in connected speech. These changes fall into two main types: assimilation and elision. ASSIMILATION In assimilation, one sound becomes phonetically similar to an adjacent sound. For example, the two words this and shop in isolation are pronounced - this /ðɪs/ - shop /ʃɒp/. In rapid speech, when the two words are pronounced together, the sound /s/ in this is influenced by the following initial sound and changes to /ʃ/. What we actually hear is: - this shop /ðɪʃʃɒp/.

  • EVALUATING an INSTRUMENT for ASSESSING CONNECTED SPEECH PERFORMANCE USING FACETS ANALYSIS YOON AH SEONG University of Hawai‘I at M Ānoa
    EVALUATING AN INSTRUMENT FOR ASSESSING CONNECTED SPEECH PERFORMANCE USING FACETS ANALYSIS YOON AH SEONG University of Hawai‘i at M ānoa ABSTRACT In the area of English pronunciation teaching, connected speech is increasingly being introduced and covered in pronunciation textbooks (e.g., Hagen, 2000; Weinstein, 2001). Connected speech is a phenomenon in spoken language that collectively includes phonological processes such as reduction, elision, intrusion, assimilation, and contraction. Several research studies have shown that connected speech instruction can help learners to more easily comprehend rapid speech used by native speakers (e.g., Brown & Hilferty, 2006; Celce-Murcia, Brinton, & Goodwin, 1996; Matsuzawa, 2006). Moreover, use of connected speech features can make learners sound more comprehensible and natural with less marked foreign accent (Brown & Kondo-Brown, 2006a; Dauer & Browne, 1992). However, compared to the growing connected speech literature regarding what forms to teach and how, there seems to be very little information on how to assess connected speech especially in terms of production. Therefore, the purpose of this study was to develop and evaluate a new test of connected speech performance within the context of an English study abroad program. The multi-faceted Rasch software FACETS was used to examine the effectiveness of the test instrument. The analyses used data from two administrations, a pretest and a posttest, and examined the relationships between examinee scores and various aspects of the testing situation (i.e., facets). The four facets investigated in this study were: (a) the examinees, (b) items, (c) raters, and (d) the rater L1 background. The results indicated that assessing the production of certain connected speech forms using this type of test instrument has potential.

  • Connected Speech in Romanian: Exploring Sound Change Through an ASR System Ioana Chitorana, Ioana Vasilescub, Bianca Vieruc, Lori Lamelb
    Connected speech in Romanian: Exploring sound change through an ASR system Ioana Chitorana, Ioana Vasilescub, Bianca Vieruc, Lori Lamelb a Université Paris Diderot and Laboratoire de Phonétique et Phonologie (UMR 7018) b LIMSI CNRS c Vocapia Research Abstract This study explores the hypothesis that traces of sound change can be found in connected speech processes as synchronic variation. To test this hypothesis we study the variation in connected speech through the output of an ASR system (Adda-Decker and Lamel, 1999). The case study is the vowel alternation [e]–[ʌ] after labials, encountered in Romanian historically, as part of a relatively sporadic sound change with unclear conditioning, as well as synchronically, as a phenomenon commonly observed in continuous speech. The specific question we address is whether the synchronic phenomenon in Romanian continuous speech is simply the result of general vowel reduction, or may reflect the sound change, with its apparent sensitivity to a labial consonantal context. We focus on the prepositions [pe] ‘on’ and [de] ‘of’, chosen specifically for their status as function words, more prone to vowel reduction than lexical words. We compare the ASR system’s choice of two transcription variants and their respective contexts. The results of this comparison suggest that the synchronic variation is grounded in the historical sound change, thus motivating a future systematic study of controlled speech, to determine the exact role of segmental contextual factors. The main result is that the selection of transcription variants is significantly different for the two prepositions. This allows us to better understand the conditioning environment of the relevant sound change, and reveals the language-specific articulatory and co-articulatory settings and dynamic patterns that may have led to it, as they emerge and can be observed in continuous speech.

  • Assimilation in English Connected Speech
    Assimilation in English Connected Speech Assist. Lecturer Iman Farhan Mohammed Al-Mustansiriya University/ College of Arts/ Department of English Language البريد اﻹليكتروني: [email protected] 303 Abstract The current study focuses on one of the most significant problems of English phonemic analysis that is the phenomenon of assimilation. The notion assimilation is discussed, by many phoneticians and phonologists like Roach, Carr and many others, as a phonological process when there is a change of one sound into another because of adjacent segments. Assimilation has many types with different forms. It also has its own rules that constraint sounds and how a feature of a sound spreads to an adjacent sound. The aim of this paper is an attempt to provide an adequate background knowledge for those who are interested in this phonetic phenomenon. Keywords: (assimilation - speech – rules) 1.1 Assimilation: Overview Broadly speaking, Crystal (2011:39) states that assimilation means the effect that is expressed by one sound segment upon the production of another, so that the sounds become more similar. In this regard, Trask (2000:30) argues that the term assimilation is any syntagmatic change in which some sound seems more identical in nature to another sound in the same sequence, usually within one phonological word or phrase. Besides, Carr, (2008:16) assumes that assimilation is a process in which two, usually adjacent, segments appear more identical to each other. An instance of assimilation for place of articulation can be seen in sequences such as ten boys in 304 English, where the /n/ of ten seems to assimilate to the place of articulation of the following bilabial stop /tembɔɪz/.

  • Chapter One Introduction
    CHAPTER ONE INTRODUCTION 1.0 Overview This chapter provides description of theoretical frame work of the study, focusing largely on the study problem and methodology. 1.1 Context of the Study In learning L2 one of the most difficult area facing L2 learners is getting a better grasp of pronunciation. Compared with other branches of linguistics such as; syntax, morphology,…. over which learners can have a reasonable understanding, pronunciation poses a much difficult stance to learn. According to Avery & Ehrlich (1992) the nature of a foreign accent is determined to a large extent by the learners‟ L1. In other words, the sound system and the syllable structure of L1 have some influence on the production of the L2. In the same view, Swan & Smith (1987) suggest that the pronunciation errors made by L2 learners are considered not to be random attempts to produce unfamiliar sounds, but rather reflection of their L1 sound system. In 1953, Ulrish Weinreich wrote about interference as instances of deviation from the norms of other languages which occur in the speech of bilinguals as a result of their familiarity with more than one language. Consequently, this fits with the transferring of entire L1 system in the process of learning of L2. In other words that is of transferring phonemes and their variants, stress, rhythm patterns and their interaction with other phonemes. Similarity of sounds structure and distribution in learning occurs by simple transfer without any sort of difficulty, but when there is no similarity, an L2 learner finds difficulties. It‟s natural to accept that an L1 speaker can easily recognize a foreign pronunciation or accent of non- L1 speakers.

  • Sandhi-Variation and the Comprehension of Spoken English for Japanese Learners
    SANDHI-VARIATION AND THE COMPREHENSION OF SPOKEN ENGLISH FOR JAPANESE LEARNERS A Dissertation Submitted to the Temple University Graduate Board In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy By Brett Collins May, 2018 Examining Committee Members David Beglar, Advisory Chair, Teaching and Learning Tomoko Nemoto, Teaching and Learning Rob Waring, External Member, Notre Dame Seishin University Kazuya Saito, External Member, Birkbeck, University of London © Copyright 2018 by Brett Collins ii ABSTRACT In this study I addressed three problems related to how sandhi-variation , the adjustments made by speakers to the speech stream, filters comprehension for second language listener processing. The first was the need to better understand proficiency problems encountered by L2 listeners as they decode the speech stream with the phonological features of sandhi-variation, elision and assimilation, by investigating the item difficulty hierarchy of the phenomena. The second was the scarcity of research on aural processing abilities of second language learners in relation to their understanding sandhi-variation in aural texts. The third concerns the lack of research investigating links between learners’ backgrounds and their ability to handle listening texts, especially variations in the speech stream in target aural texts. The purpose of this study was threefold. My first purpose was to investigate the item difficulty hierarchy of sandhi- variation types that learners have in relation to L2 listening proficiency. My second purpose was to evaluate links between aural input containing elision and assimilation and second language aural processing, to provide insight into how learners deal with sandhi- variation as they process such input.

  • SYLLABLE FUSION in HONG KONG CANTONESE CONNECTED SPEECH DISSERTATION Presented in Partial Fulfillment of the Requirements for Th
    SYLLABLE FUSION IN HONG KONG CANTONESE CONNECTED SPEECH DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Wai Yi Peggy Wong, B.A., M.A. ***** The Ohio State University 2006 Dissertation Committee: Professor Mary E Beckman, Adviser _________________________ Professor Marjorie K M Chan, Co-Adviser Adviser Professor Chris Brew _________________________ Co-Adviser Linguistics Graduate Program © Copyright by Wai Yi Peggy Wong 2006 ABSTRACT This dissertation is about “syllable fusion” in Hong Kong Cantonese. Syllable fusion is a connected-speech phenomenon whereby boundaries between syllables are blurred together in a way that suggests an intermediate level of grouping between the syllable and the larger intonational phrase. Previous studies of this phenomenon have focused on extreme cases — i.e. whole segments (consonants and/or vowels) are deleted at the relevant syllable boundary. By contrast, in this dissertation, “syllable fusion” refers to a variety of changes affecting a sequence of two syllables that range along a continuum from “mild” to “extreme” blending together of the syllables. Less extreme changes include assimilation, consonant lenition and so on, any substantial weakening or effective deletion of the oral gesture(s) of the segment(s) contiguous to the syllable boundary, and the sometimes attendant resyllabifications that create “fused forms”. More extreme fusion can simplify contour tones and “merge” the qualities of vowels that would be separated by an onset or coda consonant at more “normal” degrees of disjuncture between words. ii The idea that motivates the experiments described in this dissertation is that the occurrence of syllable fusion marks prosodic grouping at the level of the “foot”, a phonological constituent which has been proposed to account for prosodic phenomena such as the process of tone sandhi and neutral tone in other varieties of Chinese.

  • Stop Epenthesis in English F Marios Fourakis Centra L Institute for the Deaf
    Journal of Phonetics (1986) 14, 197 22 1 I Stop Epenthesis in English f Marios Fourakis Centra l Institute for the Deaf. 818 South Euclid, St. Louis, Mis souri 63110. U.S.A. and Robert Port lndiana University , Bloomington, Indiana 47405, U.S.A. Received 14th May 1985. and in revisedform I Ith January 1986 Some phonologists have claimed that the insertion of a stop between a sonorant and a fricative consonant in syllable-final sonorant­ fricative clusters follows from universal constraints on the human speech perception and produ ction mechanism. Others have claimed that the intrusive stops are products of language or dialect specific phonological rules that are stated in the grammar . In this experiment we examined the produ ction of sonorant - fricative and sonorant-stop­ fricative clusters by two groups of English speakers. One spoke a South African dialect and the other an American mid-western dfalect. The words tested ended in clusters of [n) or [l) plus [s) or [ts) and their voiced counterparts. Spectrographic analysis revealed that the South African speakers maintained a clear contrast between sonorant­ fricative and sonorant-stop-fricative clusters. The American speakers always inserted stops after the sonorant if the fricative was voiceless, but when the fricative was voiced, they more often omitted the stop in underlying clusters containing a stop (/ldz/ or /ndz/) but sometimes inserted a stop in clusters such as /n2/ or /lz/. Measurements of the durations of the vowels, sonorants, stops and the final fricatives were made from the spectrograms . The inserted stop in the American productions was significantly shorter than the underlying one and its presence also affected the duration of the preceding nasal.

  • The Tune Drives the Text - Competing Information Channels of Speech Shape Phonological Systems
    The tune drives the text - Competing information channels of speech shape phonological systems Cite as: Roettger, Timo B. & Grice, Martine (2019). The tune drives the text - Competing information channels of speech shape phonological systems. Language Dynamics and Change, 9(2), 265–298. DOI: 10.1163/22105832-00902006 Abstract In recent years there has been increasing recognition of the vital role of intonation in speech communication. While contemporary models represent intonation – the tune – and the text that bears it on separate autonomous tiers, this paper distils previously unconnected findings across diverse languages that point to important interactions between these two tiers. These interactions often involve vowels, which, given their rich harmonic structure, lend themselves particularly well to the transmission of pitch. Existing vowels can be lengthened, new vowels can be inserted and loss of their voicing can be blocked. The negotiation between tune and text ensures that pragmatic information is accurately transmitted and possibly plays a role in the typology of phonological systems.
