Non-word repetition may reveal different errors in naive listeners and second language learners
Jeffrey J. Holliday,Minkyoung Hong 한국음성학회 2020 말소리와 음성과학 Vol.12 No.1
The perceptual assimilation of a nonnative phonological contrast can change with linguistic experience, resulting in naïve listeners and novice second language (L2) learners potentially assimilating the members of a nonnative contrast to different native (L1) categories. While it has been shown that this sort of change can affect the discrimination of the nonnative contrast, it has not been tested whether such a change could have consequences for the production of the contrast. In this study, L1 speakers of Mandarin Chinese who were (1) naïve to Korean, (2) novice L2 learners, or (3) advanced L2 learners participated in a Korean non-word repetition task using word-initial sibilants. The initial CVs of their repetitions were then played to L1 Korean listeners who categorized the initial consonant. The naïve talkers were more likely to repeat an initial /s<SUP>h</SUP>a/ as an affricate, whereas the L2 learners repeated it as a fricative, in line with how these listeners have been shown to assimilate Korean sibilants to Mandarin categories. This result suggests that errors in the production of new words presented auditorily to nonnative listeners may be driven by how they perceptually assimilate the nonnative sounds, emphasizing the need to better understand what drives changes in perceptual assimilation that accompany increased linguistic experience.

The acoustic realization of the Korean sibilant fricative contrast in Seoul and Daegu
Holliday Jeffrey J. 한국음성학회 2012 말소리와 음성과학 Vol.4 No.1
The neutralization of /sh/ and /s*/ in Gyeongsang dialects is a culturally salient stereotype that has received relatively little attention in the phonetic literature. The current study is a more extensive acoustic comparison of the sibilant fricative productions of Seoul and Gyeongsang dialect speakers. The data presented here suggest that, at least for young Seoul and Daegu speakers, there are few inter-dialectal differences in sibilant fricative production. These conclusions are supported by the output of mixed effects logistic regression models that used aspiration duration, spectral mean of the frication noise, and H1-H2 of the following vowel to predict fricative type in each dialect. The clearest dialect difference was that Daegu speakers' /sh/ and /s*/ productions had overall shorter aspiration durations than those of Seoul speakers, suggesting the opposite of the traditional "/s*/ produced as [sh]" stereotype of Gyeongsang dialects. Further work is needed to investigate whether /sh/-/s*/ neutralization in Daegu is perceptual rather than acoustic in nature.

Executive function and Korean children’s stop production
공은정,이현정,Jeffrey J. Holliday 한국음성학회 2023 말소리와 음성과학 Vol.15 No.3
Previous studies have established a role for cognitive differences in explaining variability in speech processing across individuals. In the case of perceptual cue weighting in the context of a sound change, studies have produced conflicting results regarding the relationship between executive function and the use of redundant cues. The current study aimed to explore this relationship in acoustic cue weighting during speech production. Forty-one Korean-speaking children read a list of stop-initial words and completed two tests that assess executive function, i.e., Dimensional Change Card Sorting (DCCS) and digit n-back. Voice onset time (VOT) and fundamental frequency (F0) were measured in each word, and analyses were carried out to determine the extent to which children’s executive function predicted their use of both informative and less informative cues to the three pairs comprising the Korean three-way stop laryngeal contrast. No evidence was found for a relationship between cognitive ability and acoustic cue weighting in production, which is at odds with previous, albeit conflicting, results for speech perception. While this result may be due to the lack of task demands in the production task used here, it nevertheless expands the empirical ground upon which future work in this area may proceed.

A phonetic investigation of some temporal properties of Paite obstruents
Chiin Ngaihmuan Ngaihte,Jeffrey J. Holliday,Kelly H. Berkson 한국음운론학회 2020 음성·음운·형태론 연구 Vol.26 No.2
Voice Onset Time has been successfully used to capture stop contrasts in a variety of languages, but much of the existing work has focused on 2-category languages, meaning those with 2-way laryngeal contrasts. Data for 3-category languages remain somewhat limited. Almost completely unrepresented in the existing literature is the Kuki-Chin sub-branch of the Tibeto-Burman language family. Kuki-Chin languages generally contain three stop types, contrasting voiced, voiceless, and aspirated stops (e.g. /d/ vs. /t/ vs. /th/). This study presents an instrumental analysis of data from 12 speakers of Paite, an under-documented Kuki-Chin language from Northern India. We report the distribution of VOT across the three stop types and places of articulation, along with data that shed light on two unresolved issues in previous phonological descriptions: (1) both stop and fricative realizations have been reported for the sound generally referred to as the aspirated velar stop; (2) similarly, phonetically variable realizations have been reported for two affricate graphemes, <c> and <ch>. As previous reports of variability have been largely impressionistic, the data presented here help clarify the nature of the variation. In addition to representing the first-ever corpus of acoustic data in Paite, the current work is also, to the best of our knowledge, the first substantive study of VOT in a 3-category Kuki-Chin language.
