Poster VI-2 The articulatory and acoustic study of fricative vowels in Suzhou Chinese
Feng Ling, Department of Chinese, Translation and Linguistics, City University of Hong Kong
Paper File
  The fricative vowels in Suzhou Chinese are investigated in this study. The acoustic results show that the fricative vowel has more noise and a lower F2 than its pure vowel counterpart. The F1 and F2 relations with the vowel height and backness of common vowels are not appropriate for the fricative vowels. The lower F2 of fricative vowel is due to the vowel constriction located in a more anterior position than the pure close vowel.

  This article describes the changes in oral pressure during [pk] and [kp] sequences in asymmetrical [i:,u:] vowel contexts as well as in symmetrical [i:,u:,a:] contexts. Observed patterns are in part similar to those described in the literature. Although there are speakers who consistently use certain patterns in a given context, the patterns can also vary both within and across speakers.

  Within current phonological theories the typological patterns of regressive place assimilation are treated as the consequence of interactions among constraints that have acoustic-perceptual teleologies. Little is known, however, about the articulatory patterns underlying the typology of regressive place assimilation. Our current EMA study aims to investigate these patterns. Specifically, the timing and magnitude of tongue tip, lower lip, and tongue back movements of C1C2 productions across word boundaries in German will be studied. The following factors were controlled: manner of articulation of C1, and place of articulation of C2, and lexical factors. The results provide evidence for a greater reduction of tongue tip movements in function as compared to content words. Reduction of tongue tip movements was particularly likely in function words with /n#k/ clusters. In addition, this word pair had a high co-occurrence frequency. With regard to C1C2 overlap results werde mixed and warrents further investigations.

  Glottal and epiglottal (pharyngeal) articulations, including sounds native to Arabic and canonical profiles, are examined to determine the levels of laryngeal stricture and muscular synergy involved in their production. An array of laryngeal manners of articulation is tested using video and high-speed laryngoscopic filming to identify active glottal, ventricular, and aryepiglottic processes. The focus is on the ventricular level of laryngeal control, which has not been adequately described in the literature. Glottal stop is shown to depend on the ventricular level; the LCA, LTA, AE, TE, and VEN muscles are implicated in ventricular and aryepiglottic adjustments; and the vibratory patterns of aryepiglottic trilling are described.

  Purpose: A neural model of speech production based on self-organizing neural networks is introduced. The model is capable of describing speech acquisition stages as well as speech perception effects. Method: 20 instances of the neural model were trained imita­ting early stages of speech acquisition (babbling and imitation) in order to create 20 different virtual toddlers. Perceptual experiments were performed using these virtual listeners. Results: Typical effects of speech perception occur by performing identification experiments on vocalic and conso­nantal acoustic stimulus continua. Consonantal ca­tegorical perception directly occurs during babb­ling while the perceptual magnet effect occurs later on during language specific imitation training. Conclusion: This neural model of speech produc­tion using self-organizing neural networks is capa­ble (a) of illustrating the close relationship between production and perception of speech and (b) of elu­cidating the formation of speech perception effects during speech acquisition.

  The native language affects non-native languages in such a way that the phoneme categories formed in infancy impede the perception of sound contrasts within the native language categories. Balanced bilinguals form in this respect an interesting group: do the two languages affect each other on the perceptual level, or can the two systems be kept apart in a behavioral attention-demanding task? In order to study the vowel perception of balanced bilinguals, a behavioral identification task was performed. In the light of the obtained results, it seems that bilinguals are behaviorally able to keep the two languages apart, and consciously choose to use one or the other in an attention-demanding identification task. Keywords: Bilingualism, vowel perception, identification, context language.

  Mandarin syllable structure does not allow consonant clusters. In this study, we investigated the perception of English initial consonant clusters by native speakers of Taiwanese Mandarin (TM). The results show that the factors which affect the perception of non-native clusters are the phonemic inventory of the native language, coarticulation within the cluster, articulatory command in producing consonant clusters, and native-language phonotactic constraints. However, these constraints are not an important factor in the perception of non-native clusters by TM speakers.
Poster VI-16 Question intonation in non-scripted Danish dialogues

Paper File
  Global intonation contour slopes in read speech have been found to vary systematically according to utterance type. Statements have the steepest gradients, wh-question contours are slightly less steep, questions with word order inversion less steeply falling again, and so-called declarative questions have no gradient at all, i.e. their global contour is level. Furthermore, in all but the very shortest utterances onset and offset of the global intonation contour appear relatively constant in the frequency range across varying utterance length. This paper is a first exploration into Danish question intonation in nonscripted speech.

  This paper presents a revised version of an implementation of the Momel and INTSINT algorithms for the automatic modelling and symbolic coding of intonation patterns. The algorithms are implemented as external functions (respectively a C program and a Perl script), which are seamlessly integrated into the Praat speech manipulation software by means of the recently proposed plugin facility for Praat. Pitch detection is carried out using a subroutine to calculate optimal values of maximum and minimum F0 automatically. The implementation of the Momel algorithm incorporates a greatly improved treatment of the modelling of pitch contours in the vicinity of onsets and offsets of voicing. The version of the INTSINT algorithm implemented is the two parameter robust version which has been described in recent publications.

  This paper introduces a new research project Simulating Intonational Varieties of Swedish (SIMULEKT). The basic goal of the project is to produce more precise and thorough knowledge about some major intonational varieties of Swedish. In this research effort the Swedish prosody model plays a prominent role. A fundamental idea is to take advantage of speech synthesis in different forms. In our analysis and synthesis work we will focus on some major intonational types: South, Göta, Svea, Gotland, Dala, North, and Finland Swedish. The significance of our project work will be within basic research as well as in speech technology applications.
Poster VI-22 Czech Speech Rhythm and the Rhythm Class Hypothesis
Jana Dankovicova, University College London, UK
Volker Dellwo, University College London, UK
Paper File
  While a number of languages have been classified as either syllable- or stress-timed, the case of Czech remains unclear. In this paper we make predictions about Czech rhythm on the basis of our analysis of syllable complexity in recorded samples of Czech. The results on syllable complexity show mixed features. This is reflected in the classification of Czech rhythm using rhythm measures based on durational variability of consonantal and vocalic intervals.

  A series of musical rising two-tone patterns comprising13 intervals, from unison to octave, is compared with two German nuclear contours, rise and rise-fall, both on utterances with upbeat-downbeat structure. The two-tone patterns are viewed as potential musical representations of the prosodic contours. However, because of rhythmic constraints they can only cover part of the prosodic contour information. Two ABX tests were carried out to examine whether the loss of contour information in the two-tone patterns is compensated for with other musical features. Results show that large and dissonant intervals are more likely assigned to the rise contour. Moreover, the rise is judged closer to the risings fifth (a I-V progression) and the rise-fall closer to the rising fourth (a V-I progression). This means that the relation between speech melody and musical melody includes aspects that are usually trieated as exclusively musical.

  Studies of duration in Welsh have concentrated on specific environments, such as word-final, pre-final and pre-pre-final positions, in relation to the positions of linguistic stress and phonetic pitch accent. The present approach is broader, in that it looks at the temporal patterning of syllable and foot sequences. First, general global and local measures of isochrony and irregularity are applied (standard deviation; pairwise variability). Second, since isochrony is a necessary but not a sufficient correlate of rhythm, a new algorithm is introduced for characterising grouping properties. Third, syllable sequences are segmented into feet using alternative duration relations and examined for their relation to grammatical groups. It appears that Welsh duration patterns are neither syllable-timed nor foot-timed in the accepted sense, but have what may be called a “rallentando timing”, in which sequences of increasing length mark grammatically relevant prosodic units.
Poster VI-28 Towards an Integrated Understanding of Speech Overlaps in Conversation

Paper File
  We investigate factors that affect speech overlaps in conversation, using large corpora of conversational telephone speech. We analyzed two types of speech overlaps: 1. One side takes over the turn before the other side finishes (Turn-taking type); 2. One side speaks in the middle of the other side’s turn (Backchannel type). We found that Japanese conversations have more short Turn-taking type of overlap segments than the other languages. In general, females make more speech overlaps of both types than males, both males and females make more overlaps when talking to females than talking to males. People make less overlaps when talking with strangers than talking with familiars, and the frequency of speech overlaps is significantly affected by conversation topics. Finally, the two conversation sides are highly correlated on their frequencies of using Turn-taking type of overlaps but not Backchannel type.
Poster VI-30 Processing of disfluencies as a function of error type and age

Paper File
  The effects that speakers’ disfluencies have on the listener are rather complex. Speech perception is an incredibly fast process, given that while the mechanism interprets the incoming waveform as a series of linguistic segments and suprasegmentals, it is also continuously ready to receive and correct the incoming erroneous messages. The goal of the present experiment was to describe the correction process and determine its efficiency. Various types of disfluency were tested with nine-year-old children, young adults, and elders. The results show that the time span of the corrective process depends upon the type of disfluency, the context, and the listener’s age. The higher operational level the production error involves the more time is required for correcting it and the corrections are poorer than at lower operational levels.

  Paper deals with the problem of the historical development of unstressed vowel systems in Russian. A phonetic explanation for the development of all existing types is suggested on the basis of a hypothesis that assumes the priority of the non-dissimilative type. A new, probably most archaic, type of unstressed vowel system in Russian is shown to provide another argument in favour of the suggested explanation.

  This paper presents the phonemic vowel typology of the 89 areally and genetically balanced Chinese dialects. Eight types of phonemic vowel systems are identified. The number of the vowel phoneme in the vowel systems ranges from 4 to 11. The 7-vowel system is the optimum system, whereas the 4-, 10- and 11-vowels systems are less common. The most frequently occurring vowel phonemes are /i a u/, to be followed by unrounded front mid vowels and rounded back mid vowels. As for the nasal vowels, the nasal [a] appears most frequently. Compared to the oral vowels, the number of nasal vowel types is smaller and the frequency of the nasal vowels in much lower. The findings are compared with those in the early studies of universals of vowel systems.

  This study is a description of the monophthongs of East Anglia speech, an area in the south east of England. Formant measurements were computed on 11 vowels in /hVd/ contexts. The results are compared with those of previously published works on standard British English. Our findings highlight the similarities and differences between the two systems. Particular attention is paid to age-related issues and speaker normalization.

  This paper presents findings from an exploratory study of the effect of speech rate on the variable realisation of /p t k/ in the Tyneside (north-east England) variety of English. While previous work on this particular variety has shown that patterns of variation observed in /p t k/ are strongly related to a range of social factors, in line with most work on sociophonetic variation there has been relatively little focus to date on the possible role of prosodic factors in governing such inter- and intra-speaker variation. This study considers one such factor (speech rate) in the performance of 32 speakers on a sentence production task. Findings suggest that rate cannot be entirely excluded as a factor in accounting for the patterns of variation observed, but that its influence is somewhat marginal being clearly present only at particularly high rates.

  Development in the production of /r/ is attested in a speaker of Standard Southern British English (SSBE) between the ages of 3;8 and 3;11. The progression towards adult-like apical approximant /r/ is manifested along multiple dimensions and primarily involves a gradual raising of F2 and lowering of F3. In addition to changes in absolute frequencies of F2 and F3, however, we find that this speaker’s development involves general reduction in variation of her output, elimination of apparent [w] substitutions concomitant with increased labiodental realisations, and decrease of F3-F2 distance. This latter acoustic cue is worth additional exploration, as F3 may remain stable between perceptibly different outputs. Moreover, the data show that development of /r/ may include a shift in the relative salience of F3 by means of increase in that formant’s amplitude, again compensating for non-lowering of F3 to canonically /r/-like frequencies.

  The current study experimentally manipulates attention to different aspects of the phonetic signal during learning. In an identification task, two native English speaking participant groups were trained on novel Hindi words containing unfamiliar consonants and vowels. Both groups were presented with the same auditory stimuli. One group was instructed to attend to the Hindi consonants and the other to the Hindi vowels presented in these words. The group oriented toward consonants showed greater consonant discrimination ability than the group oriented toward vowels in a post-test/pre-test comparison. These results confirm the importance of attentional mechanisms for phonetic learning.

  Acquiring L2 vowel quantity can be difficult for native speakers of languages like English where vowel duration cues stress. This study tested whether English learners of Czech would categorize short and long vowels in a stressed or in an unstressed syllable differently than native listeners. The role of L2 experience was also explored. Results showed that the native and non-native listeners did not differ in category boundary locations in either syllable, although non-native perception was less categorical in the unstressed syllable. No effect of experience was found. It is concluded that the L2 learners redefined the value of vowel duration as a cue.

  This paper reports the development and evaluation of an online distance course making available most of the elements of traditional on-campus phonetic training within a Virtual Learning Environment (VLE). Issues associated with the use of phonetic symbols in the teaching materials and communication tools of a VLE are addressed. An outline is presented of an up-to-date, research-driven syllabus for a distance course in English phonetics with associated exercises, ear-training and assessments. An eight-week pilot of the new course attracted 25 students across five continents, indicating a healthy global market for a course of this type. Retention rate to final assessment was 64%; an evaluation questionnaire assessing satisfaction on a five-point scale (1=best) showed an average score of 1.34.

  In the paper the experiments on perceptual assessment of Russian-accented Estonian are introduced. Speech samples were recorded from 20 speakers with a Russian background; clips of about 20 seconds from each speaker were selected for perceptual assessment. Two tests were carried out: first, 20 native Estonian speakers judged the samples and rated the degree of foreign accent on a six-point interval scale; secondly, two experienced phoneticians analyzed the same samples and compiled the list of pronunciation errors. The higher is the degree of accentedness judged by naďve listeners the more pronunciation errors was found by the experts. This general tendency is violated by several opposite examples. Finally, a simple method for accent assessment is proposed.

  This study aims to investigate the effects of phonetic distance, learning context and learner proficiency on L2 perception of English liquids. Reaction time difference between the pre- and post-tests was analyzed. Results showed that the natural context induced the most progress for participants of a lower L2 proficiency level, while no preference was shown for those of a higher proficiency level. In general, L2 learners showed more progress for liquids occurring in novel phonotactic structures. Phone effect was significant only when L2 learners of lower proficiency perceived liquids in the singleton position.

  This paper examines intrinsic vowel pitch (IF0) in Moroccan Standard Arabic and Belgian Standard Dutch in order to investigate the hypothesis that IF0 may depend on the size of the vowel inventory. The results of a production task with 11 Moroccan native speakers of Standard Arabic and 10 Belgian native speakers of Dutch reveal that IF0 in Arabic is significantly smaller (1.28 ST) than in Dutch (2.78 ST). These results are suggestive of a possible influence on IF0 of the size of the vowel inventory in a language. The effect of speaker sex on IF0 was not significant, while the front-back distinction in the articulation of vowels was significant in Belgian Dutch.

  This paper focuses on perception of Japanese voiceless plosives by Korean listeners to: 1) assess whether the categorization of utterance initial- and medial- Japanese plosives into Korean three-way laryngeal categories is the same as in loanwords from Japanese; 2) identify the acoustic cues relevant to the identified patterns. We used modified stimuli from nonsense word tokens of native Japanese speakers, manipulating F0, amplitude and temporal characteristics. Loanwords represented only a part of the perception patterns: utterance initial [p] was mostly heard as aspirated and medial [p] was identified as either aspirated or fortis. The acoustic cues of F0 on the following vowel and temporal characteristics particular to the positions had effects on the laryngeal percept.
Poster VI-56 Implicit phonetic imitation is constrained by phonemic contrast
Kuniko Nielsen, UCLA Department of Linguistics
Paper File
  The imitation paradigm (Goldinger, 1998) has shown that subjects shift their production in the direction of the target, indicating the use of episodic traces in speech perception. By using this paradigm, two experiments were carried out to test: 1) if/how this implicit phonetic imitation interacts with linguistic representations when the change might impair linguistic contrast; 2) whether phonetic imitation can be generalized, and 3) whether word-level specificity can be obtained through physical measurements of a phonetic feature. The results revealed a significant effect of implicit phonetic imitation for extended VOTs, although there was no imitation observed for reduced VOTs. Furthermore, the imitated feature (extended VOT) was generalized to new instances of the target phoneme /p/ as well as to the new segment /k/. These results indicate that 1) knowledge of phonemic contrast modulates the implicit phonetic imitation, and 2) speakers possess sub-phonemic representations.

  The abundant research on lexical access in the last 30 years has shown that context effects such as lexical status, morphological complexity, and neighborhood density can affect word recognition. Very little research has investigated interactions between perceptual distinctiveness and context effects. This study used a spoken word recognition in noise experiment with German words and nonwords to research this interaction. Results showed a processing advantage for monomorphemic words over bimorphemic words, and that listeners are particularly sensitive to morphological information when presented with highly confusable stimuli.

  For 43 pairs of same and different voices in different speech contexts of real cases, LTASS has been made for the area between 800 and 3500 Hz on the basis of the recordings of speech over GSM mobile phones. SDDD and similarity indices in different speech context have been compared. For the sake of comparison of data achieved by the two speech recordings of standardized text read by 30 male and 35 female speakers, average values of indices are calculated for the same and different people: from 0 to 10 kHz and filtered voices from 0.8 to 3.5 kHz. The results of t-test have shown that the groups differ significantly, respectively greatest in the group of male voices recorded in the studio (0-10 kHz: p<0.001), filtered studio voices (p<0.001) and real cases (SDDD: p<0.01; R: p=0.01).

  An important challenge in the study of speech production is to gain theoretical understanding of how laryngeal and supralaryngeal movements are coordinated, and to determine which factors influence this coordination. This study investigates how these movements are coordinated during the production of completely voiceless words and sentences in Tashlhiyt Berber. Results show that the glottis does not simply remain open but that glottal aperture is continuously modulated in a manner that can be related quite systematically to the phonetic nature of the segments present in the sequence.

  The cognitive processing involved in the decoding of emotional expressions vs. attitudes in speech, as well as the modeling of emotional prosody as contours vs. gradual cues are recurrent question. This work aims at measuring the anticipated perception of emotions on minimal linguistic units, to evaluate if the underlying processing is compatible with the hypothesis of gradient contours processing. Selected monosyllabic stimuli extracted from an expressive corpus and expressing anxiety, disappointment, disgust, disquiet, joy, resignation, sadness and satisfaction, were gradually presented to naďve judges in a gating experiment. Results show that identification along gates of most of expressions follow a linear pattern typical of a contour-like processing, while expressions of satisfaction present distinct gradient values that make possible an early identification of affective values.

  The current study investigates acoustic correlates associated with friendly formal and friendly informal speaking styles. A small corpus of speech was recorded by a native speaker of American English. The results revealed that the most distinctive feature differentiating the two styles is the fundamental frequency. There was also a small difference found in the articularion rate and RMS energy between the two styles.
