Shina is an endangered Indo-Aryan (Dardic) language spoken in Gilgit, Northern Pakistan. The present study investigates the acoustic correlates of Shina’s three-way stop laryngeal contrast across five places of articulation. A wide range of acoustic correlates were measured including fundamental frequency (F0), spectral tilt (H1*-H2*, H1*-A1*, H1*-A2*, and H1*-A3*), and cepstral peak prominence (CPP). Voiceless aspirated stops were characterized by higher fundamental frequency, spectral tilt, and cepstral peak prominence, compared to voiceless unaspirated and voiced unaspirated stops. These results suggest that Shina is among those languages which have a raising effect of aspiration on the pitch and spectral tilt onsets of the following vowels. Positive correlations among fundamental frequency, spectral tilt, and cepstral peak prominence were observed. The findings of this study will contribute to the phonetic documentation of endangered Dardic languages.

COVID-19 is transmitted through sneezing and coughing, which constitute its basic symptoms, due to the high velocity of droplets produced by these activities; however, recent studies have demonstrated that a large quantity of droplets may be produced even by talking or breathing [2], [3]. Studies with respect to the effect of phoneme type (the main sound unit of speech) on the production of droplets are only few in number. For example [1], argued that SARS, which could be transmitted through droplets, did not infect one to three millions of Japanese who travelled to China in 2000, while American visitors in China at the same period were infected. The author added that Japanese aspirated stops like /p/, which are said to produce a lot of droplets, are not used that much in Japanese compared to English. Therefore, he concluded that the fact that Chinese shop assistants who might have been speaking to Japanese tourists in Japanese but to American tourists in English might explain the zero infection of Japanese tourists. In this paper, we support the hypothesis reported in Inouye [1] that aspirated consonants might produce more droplets in comparison to unaspirated consonants. To check this hypothesis, we have taken the 26 countries mostly infected (more than 1000 cases) by the COVID-19 as of 23rd of March. We excluded Switzerland since there are many official languages in its territory. Also, we excluded outliers, that is, countries with many cases (e.g., Italy) or very few cases (e.g., Japan) per million of population. The independent t-test analysis conducted in R showed no significant differences in cases of inflected individuals between the languages with aspiration (M = 254.9, SD = 159.5) and the languages without aspiration (M = 206, SD = 121.9), [t(18) = 0.73, p > .05]. Open in a separate window Although no statistical differences were found between the two types of languages, we observed that in countries in which the dominant language has aspirated consonants there were more cases of individuals infected by COVID-19 in comparison to countries in which the dominant language does not have aspirated consonants. These findings can offer epidemiological implications for COVID-19 transmission in each country since this transmission may be based to some extent on whether there are or no aspirated consonants in the dominant language spoken in each country.

Madurese, a Malayo-Polynesian language of Indonesia, is of interest both areally and typologically: it is described as having a three-way laryngeal contrast between voiced, voiceless unaspirated, and voiceless aspirated plosives, along with a strict phonotactic restriction on consonant voicing-vowel height sequences. An acoustic analysis of Madurese consonants and vowels obtained from the recordings of 15 speakers is presented to assess whether its voiced and aspirated plosives might share acoustic properties indicative of a shared articulatory gesture. Although voiced and voiceless aspirated plosives in word-initial position pattern together in terms of several spectral balance measures, these are most likely due to the following vowel quality, rather than aspects of a shared laryngeal configuration. Conversely, the voiceless (aspirated and unaspirated) plosives share multiple acoustic properties, including F0 trajectories and overlapping voicing lag time distributions, suggesting that they share a glottal aperture target. The implications of these findings for the typology of laryngeal contrasts and the historical evolution of the Madurese consonant-vowel co-occurrence restriction are discussed.

This study examines the acoustic properties concerning tonal split and stop onsets in an under-documented Wu Chinese variety, Lili Wu, using speech production data collected from field research. Lili Wu Chinese has been reported to demonstrate an unusual tonal split phenomenon known as "aspiration-induced tonal split" (ATS). ATS refers to the distinct lowering of f0 of a lexical tone over syllables beginning with a voiceless aspirated obstruent, compared to that of syllables beginning with an unaspirated obstruent. Two debates lingering in the existing literature are discussed: (i) is ATS an on-going change or a completed change? and (ii) is it onset aspiration or vowel breathiness that directly triggers ATS? Results suggest that ATS is a completed change, which, however, is conditioned by tonal contexts. Regarding the second debate, results suggest that neither aspiration nor breathiness serves as the direct trigger for tonal split. Moreover, one unexpected on-going sound change was observed: The breathiness of vowels after voiced onsets seems to be disappearing among the younger generation. These findings extend the understanding of the acoustic properties of tonal development in a complex system and highlight the importance of experimental methods in understanding the sound structure and changes of under-documented languages.

Vowels are longer before voiced than voiceless obstruents in many languages. Work on how this effect interacts with aspiration has been limited. This study presents data from Hindi and Telugu on vowel duration and other acoustic characteristics as influenced by following consonants. Hindi vowels were significantly longer before voiced stops than voiceless stops, with no significant effect of aspiration. Telugu vowels were only slightly longer before voiced than voiceless stops; more crucially, they were shorter before aspirated stops than unaspirated stops. The Telugu results provide a parallel demonstrating the phonetic plausibility of the sound change proposed in Winter’s Law, with vowel lengthening before voiced unaspirated stops but not before voiced aspirated stops in Proto-Balto-Slavic. While the exact processes causing the voicing and aspiration effects remain unclear, this data contributes to evaluating the phenomenon. Phonetic differences between in Hindi and Telugu may also suggest characteristics of how the Proto-Balto-Slavic stop contrasts were realized.

The distribution of aspiration in Basque — with ‘aspiration’ referring to both the occurrence of [h] and of aspirated stops — shows some puzzling aspects. In some words, aspiration is ancient, in the sense that it must be assumed for the earliest reconstructable stage. In some other instances, however, it has arisen seemingly ex nihilo, as can be observed in borrowings from Latin and Romance, e.g. Latin/Romance īra > Basque hira ‘ire’, Romance taula > Basque thaula ‘board’. Most surprisingly, in some words aspiration has developed after a sonorant consonant, e.g. Romance solatz > Basque solhas ‘conversation’. Aspiration may also continue intervocalic /n/, e.g. Latin anāte > Basque ahate ‘duck’. Another unusual development is the phonologization of the contrast between aspirated and unaspirated voiceless stops triggered by a shift of the stress in some words without affecting the properties of consonants. Finally, an interdialectal alternation /k-/ ~ /g-/ ~ /h-/ ~ Ø in demonstratives and related adverbs appears to have involved fortition, contrary to initial expectations. Here we describe the environments in which aspiration is found in Basque and discuss the most likely historical developments that could have given rise to the state of affairs that we find, paying particular attention to what would appear to be unusual or unnatural sound changes. We build on prior scholarship, but this paper also contains some new hypotheses, especially regarding the aspiration in words like ahate ‘duck’. We have also tried to contribute to the dating of the different processes and to the understanding of in their causes.

Believed dialect influences speech perception by linguistically naïve speakers. How much accent-induced bias affects perception of linguistically trained speakers is still unclear. This study experimentally investigates the influence of believed dialect on plosive perception by subjects who were phonetically and phonologically trained. Identical syllables were presented twice to each subject. In one session, the subjects were informed that the variety was a Mandarin dialect which has voiceless unaspirated and aspirated voiceless stops; and in the other session that it was a Wu dialect, which has voiceless unaspirated, voiceless aspirated, and breathy stops. More breathy stops were reported if Wu was the believed dialect. Plosive phonation in Wu is related to lexical tone, and we show that lexical tone causes another bias to plosive perception. This suggests that linguistically trained transcribers are susceptible to higher order linguistic knowledge and it demonstrates the difficulty of avoiding biased perception when the coder forms a belief about the variety that he/she transcribes. We also advocate speech perception models which include a component that accounts for the role ofexpectedsounds.

An order effect was found in English infants’ discrimination of an Urdu contrast. In Experiment 1 7- and 11-month-old English infants were tested on the Urdu contrast between the affricates /tʃʰ/ and /tʃ/. The order of presentation was counterbalanced: At each age half the infants were habituated to the aspirated and tested on the unaspirated affricate, the other half habituated to the unaspirated and tested on the aspirated. As expected, younger infants discriminated the contrast whereas older infants did not, showing the expected decline in discrimination. Interestingly, order of presentation seemed to affect the older infants’ response. Experiment 2 tested the order effect directly. The results showed no asymmetry in the performance of 7-month olds but clear asymmetry in that of 11-month-olds, who discriminated the contrast only when the non-English-like aspirated affricate was presented first. Experiment 3 tested adult native-speakers of both Urdu and English. Although the English listeners showed a reduced sensitivity to the contrast, there was no effect due to order of presentation of the stimuli in either adult group. The finding of an asymmetry in the infants suggests that infants’ perceptual narrowing for speech sounds may be a more complex phenomenon than has generally been assumed.

Madurese, a Western Malayo-Polynesian language spoken on the Indonesian island of Madura, has been described as having a three-way voicing contrast (i.e. voiced, voiceless unaspirated and voiceless aspirated) in its stops. However, the fact that the VOT values for voiceless unaspirated and aspirated stops are not large and they are also followed by vowels with different height raises a question if Madurese only contrasts voiced and voiceless stops phonologically instead. The goal of this paper is to establish the phonological status of the voicing contrast in Madurese stops, arguing that Madurese can be better described as a language with a three-way contrast. For this purpose, we provide phonological evidence that includes consonant-vowel interactions, vowel harmony processes and some morphophonemic processes involving vowel height alternations. All of this evidence is also used to substantiate the proposal that consonants trigger vowel height alternation rather than vowels trigger consonant allophony.

The Shetland dialect of Scots does not contain preaspiration, a phonetic areal feature that is otherwise prevalent in languages around the North Atlantic Ocean. While it is understood that Shetland’s pre-language shift Scandinavian variety, Norn, did contain preaspiration, an analysis of phonetic transcriptions from Jakob Jakobsen’s An Etymological Dictionary of the Norn Language in Shetland, collected in the 1890s, shows a more complicated picture: preaspiration occurs in only 11% of relevant vowel-stop sequences, but in 92% of relevant sonorant-stop and sonorant-fricative sequences. This article provides a contact-based explanation of the gradual disappearance of preaspiration from Shetland. The proposed trajectory of change is made up of a series of language and dialect contact-induced sub-changes and reflects the influence of Norn as well as of successive waves of immigration from the Scottish mainland. In the first stage, during language shift, preaspiration in vowel-stop sequences disappeared as it (co-)signaled a phonemic contrast in Norn not necessary for Scots, but (non-phonemic) preaspiration in sonorant-stop/fricative sequences was retained. In a later stage, dialect contact after renewed immigration from the Scottish mainland caused voiceless stops to be unaspirated, removing the phonetic basis for preaspiration also in the remaining contexts. The study highlights the different susceptibility of phonetic and phonemic features in contact-induced change and calls for further integration of second-language acquisition study and variationist sociolinguistics into historical linguistics.

International audience; The relative fundamental frequency (RFF) was recently used to assess vocal effort in normal and dysphonic subjects since it reflects the vocal fold tension at the offset and onset of vowels with, in particular, lower values at the edges of voiced consonants compared to their voiceless counterparts. In this study, we explored the RFF variations according to the voicing status and the articulation manner of consonants, in several types of speech production known to involve different levels of vocal effort. Twelve native French speakers (6 females) with normal voice were asked to produce 24 trains of eight syllables in seven vocal conditions: spontaneous, low, high, soft, loud, breathy, and pressed voice. We consider the unaspirated voiceless and voiced consonants /p, b, f, v/ with the middle open vowel /a/. As expected, the RFF was lower for voiced than for voiceless consonants. In addition, it was lower for stops than for fricatives. The RFF was also lower for the high, loud and pressed condition while it was higher for the low, soft, and breathy conditions in comparison to the values for the spontaneous voice. The RFF measurement seems to be efficient to discern subtle levels of vocal effort in normal subjects.

While voice onset time (VOT) is known to be sensitive to a range of phonetic and linguistic factors, much less is known about VOT in spontaneous speech, since most studies consider stops in single words, in sentences, and/or in read speech. Scottish English is typically said to show less aspirated voiceless stops than other varieties of English, but there is also variation, ranging from unaspirated stops in vernacular speakers to more aspirated stops in Scottish Standard English; change in the vernacular has also been suggested. This paper presents results from a study which used a fast, semi-automated procedure for analyzing positive VOT, and applied it to stressed syllable-initial stops from a real- and apparent-time corpus of naturally-occurring spontaneous Glaswegian vernacular speech. We confirm significant effects on VOT for place of articulation and local speaking rate, and trends for vowel height and lexical frequency. With respect to time, our results are not consistent with previous work reporting generally shorter VOT in elderly speakers, since our results from models which control for local speech rate show lengthening over real-time in the elderly speakers in our sample. Overall, our findings suggest that VOT in both voiceless and voiced stops is lengthening over the course of the twentieth century in this variety of Scottish English. They also support observations from other studies, both from Scotland and beyond, indicating that gradient shifts along the VOT continuum reflect subtle sociolinguistic control.

Cajun English is as dialectal variety of English spoken in the western areas of Louisiana which shows a strong influence of French language. It appeared a century ago when French speakers were forced to change their language to English. Yet, after the 1950s and because of racial segregation (Dubois and Horvath, 1999) and a political standardization of English language as the main language for American speakers this dialect was about to disappear. Despite this fact, the current situation of Cajun English is positive in the sense that it has been recovered by the youngest generations of speakers, who are proud of being Cajun. The aim of this paper, thus, is to present the linguistic and social characteristics of Cajun Vernacular English. Concerning language, it presents peculiarities such as i) the elimination of final consonants, which involves grammatical consequences in the conjugation of verbs, ii) a reduction or absence of glides in the four long stressed vowels (Thomas, 2004), iii) a heavy nasalization of vowels, iv) the dropping of the aspirated consonant aitch and the replacement of interdental fricatives by stops, producing what is called "the paradigm 'dis, dat, dese, dose'" (Rubrecht, 1971) among others. Concerning social characteristics, this paper explores the reasons why this dialect is mainly used for tourism purposes as stated by Dubois and Hovarth 2003.

This study reexamines the typologically unusual three-way laryngeal contrast in Korean among ‘lenis’, ‘fortis’, and ‘aspirated’ voiceless plosives in light of a recent proposal by Kim and Duanmu (2004) that the contrast is really among voiced, voiceless unaspirated, and voiceless aspirated categories. The results of a cross-linguistic perception experiment conducted with 24 native Korean speakers are generally consistent with Kim and Duanmu's analysis. The data show that Korean speakers are attuned to voicing in initial position, and this is naturally accounted for by a Korean laryngeal system containing a phonologically voiced category. However, the data also suggest that an important factor in Korean speakers' perception of the ‘lenis’ (~ voiced) plosives word-initially is aspiration. Thus, even if the ‘lenis’ series is analyzed as voiced, it differs in a fundamental way from the phonetic character of other languages' voiced plosives, a finding that severely weakens the cross-linguistic thrust of Kim and Duanmu's argument.

This article examines the motivation for phonological stop assibilations, e.g. /t/ is realized as [ts], [s] or [tʃ] before /i/, from the phonetic perspective. Hall & Hamann (2003) posit the following two implications: (a) Assibilation cannot be triggered by /i/ unless it is also triggered by /j/, and (b) Voiced stops cannot undergo assibilations unless voiceless ones do. In the following study we present the results of three acoustic experiments with native speakers of German and Polish which support implications (a) and (b). In our experiments we measured the friction phase after the /t d/ release before the onset of the following high front vocoid for four speakers of German and Polish. We found that the friction phase for /tj/ was significantly longer than that of /ti/, and that the friction phase of /t/ in the assibilation context is significantly longer than that of /d/., ZAS Papers in Linguistics, Bd. 37 (2004): Papers in phonetics and phonology

The Korean stop system exhibits a three-way distinction in velar stops among /g/, /k'/ and /kh/. If the differentiation is regarded as being based on voicing, such a system is rather unusual because even a two-way distinction between a voiced and a voicless unaspirated velar stop gets easily lost in the languages of the world especially in the case of velar stops. One possibility for maintainig this distinction is that supralaryngeal characteristics like articulators' velocity, duration of surrounding vowels or stop closure duration are involved. The aim of the present study is to set up a catalogue of parameters which are involved in the distinction of Korean velar stops in intervocalic position. Two Korean speakers have been recorded via Electromagnetic Articulography. The word material consisted of VCV-sequences where V is one of the three vowels /a/, /i/ or /u/ and C one of the Korean velars /g/, /k'/ or /kh/. Articulatory and acoustic signals have been analysed It turned out that the distinction is only partly built on laryngeal parameters and that supralaryngeal characteristics differ for the three stops. Another result is that the voicing contrast is not a matter of one parameter, but there is always a set of parameters involved. Furthermore, speakers seem to have a certain freedom in the choice of these parameters., ZAS Papers in Linguistics, Bd. 32 (2003): Papers in phonology & phonetics
