Syllable Position

Purpose This retrospective analysis examined group differences in error rate across 4 contextual variables (clusters vs. singletons, syllable position, number of syllables, and articulatory phonetic features) in adults with apraxia of speech (AOS) and adults with aphasia only. Group differences in the distribution of error type across contextual variables were also examined. Method Ten individuals with acquired AOS and aphasia and 11 individuals with aphasia participated in this study. In the context of a 2-group experimental design, the influence of 4 contextual variables on error rate and error type distribution was examined via repetition of 29 multisyllabic words. Error rates were analyzed using Bayesian methods, whereas distribution of error type was examined via descriptive statistics. Results There were 4 findings of robust differences between the 2 groups. These differences were found for syllable position, number of syllables, manner of articulation, and voicing. Group differences were less robust for clusters versus singletons and place of articulation. Results of error type distribution show a high proportion of distortion and substitution errors in speakers with AOS and a high proportion of substitution and omission errors in speakers with aphasia. Conclusion Findings add to the continued effort to improve the understanding and assessment of AOS and aphasia. Several contextual variables more consistently influenced breakdown in participants with AOS compared to participants with aphasia and should be considered during the diagnostic process.

AbstractKalasha (Northwestern Indo-Aryan, spoken in Pakistan) exhibits a complex set of ten affricate phonemes, which is exceedingly rare among the world’s languages and not representative of the broader South Asian context. This paper presents results of an acoustic analysis of place contrasts (dental, retroflex, and alveolopalatal) in affricates of four laryngeal specifications (voiceless unaspirated, voiceless aspirated, non-breathy voiced, and breathy voiced). These consonants were produced by four male speakers of Kalasha in a variety of phonetic contexts, resulting in a sample of close to 700 affricate tokens. A series of acoustic analyses of the data revealed that place contrasts in Kalasha affricates are distinguished robustly by both burst/frication spectra and formant transitions, but not by duration, which correlates more with laryngeal features. Place distinctions are somewhat diminished for voiced affricates but are largely unaffected by aspiration and syllable position. Most of these results are consistent with what is known about comparable (yet laryngeally simpler) place contrasts in other languages outside of South Asia. However, some of them are unique and may reflect the typological uniqueness and complexity of Kalasha’s affricate system.

Ventricular Folds

Purpose Physiological and phonetic studies suggest that, at moderate levels of epilaryngeal stricture, the ventricular folds impinge upon the vocal folds and influence their dynamical behavior, which is thought to be responsible for constricted laryngeal sounds. In this work, the authors examine this hypothesis through biomechanical modeling. Method The dynamical response of a low-dimensional, lumped-element model of the vocal folds under the influence of vocal–ventricular fold coupling was evaluated. The model was assessed for F0 and cover-mass phase difference. Case studies of simulations of different constricted phonation types and of glottal stop illustrate various additional aspects of model performance. Results Simulated vocal–ventricular fold coupling lowers F0 and perturbs the mucosal wave. It also appears to reinforce irregular patterns of oscillation, and it can enhance laryngeal closure in glottal stop production. Conclusion The effects of simulated vocal–ventricular fold coupling are consistent with sounds, such as creaky voice, harsh voice, and glottal stop, that have been observed to involve epilaryngeal stricture and apparent contact between the vocal folds and ventricular folds. This supports the view that vocal–ventricular fold coupling is important in the vibratory dynamics of such sounds and, furthermore, suggests that these sounds may intrinsically require epilaryngeal stricture.

AbstractThis is a review article on Alwin Kloekhorst, Etymological Dictionary of the Hittite Inherited Lexicon (Leiden Indo-European Etymological Dictionary Series 5. Leiden and Boston: Brill, 2008. $199. ISBN 978 90 04 16092 7). The article addresses issues arising from Kloekhorst's depiction of Hittite cuneiform spelling conventions in the context of the wider cuneiform world (Mesopotamia and Northern Syria). In particular the representation of a glottal stop in Hittite and relevant cuneiform writing is addressed. The second part of the article addresses further individual graphic and lexical issues arising throughout the etymological dictionary.

Based on over 400 character readings in the Nancheng city dialect of Eastern Jiangxi, a synchronic phonology is outlined and some sound correspondences with the Qie Yun system are worked out. Nancheng city dialect has the general characteristics of a Gan dialect and some Min-like developments in its rhyme system. Its principal feature of interest is the glottalization of upper Departing, a shortish tone with a sharp, metallic, ringing voice quality, ending in a clear-cut fashion, though not in a glottal stop. A comparison of the spectral properties of this and other tones shows upper Departing to be characterized by a weaker first harmonic. This dialect, as well as others in the same area, bears witness to the claim, made elsewhere, that Middle Chinese Departing tone was characterized by glottalized phonation.

The current study examines the realization of adjacent vowels across word boundaries in Arabic-Spanish bilinguals and Spanish monolinguals in Puerto Rico, focusing specifically on the rate of glottal stop epenthesis in this context (e.g., hombre africano to [ˈom.bre.ʔa.fri.ˈka.no]). It was hypothesized that Arabic-Spanish bilinguals would show a higher rate of glottal stop epenthesis than Spanish monolinguals because of transfer from Arabic. In addition, we investigated the possible effects of stress, vowel height, language dominance and bilingual type on the rate of glottal stop epenthesis. Results from a reading task with 8 participants showed no significant difference in glottalization between bilinguals and monolinguals. For monolinguals, glottalization was significantly more likely when the first vowel was low or stressed; significant interactions between vowel height and stress were found for the bilingual group. Language dominance was a significant factor, with Arabic-dominant bilinguals glottalizing more than the Spanish-dominant bilinguals. In addition, early sequential bilinguals favored glottalization slightly more than simultaneous bilinguals, without reaching significance. Our data suggests some effects of syllable structure transfer from Arabic, particularly in Arabic-dominant participants. To our knowledge, our study is the first exploration of Arabic and Spanish in contact in Puerto Rico, and the first to acoustically examine the speech of Arabic-Spanish bilinguals.
