Language attitudes and identity in second dialect acquisition
This study investigates to what extent various factors affect the stop production of North Korean refugee speakers living in Seoul, South Korea, from the perspective of second dialect acquisition (SDA). The VOT and F0 values of 6,495 stops were measured from twenty-two North Korean speakers (F: 16, M: 6). The factors examined were age of arrival, length of residence (LoR), and three different aspects of social adaptation (identification, assimila…
Hotspots for acoustic politeness in Korean and Japanese deferential speech
This study extends a growing body of crosslinguistic research on multimodal politeness, with a focus on the phonetics of deferential speech in Korean and Japanese. Whereas previous studies have examined the global acoustic properties of deferential speech averaged across the entire utterance, we hypothesize that acoustic characteristics are localized into specific politeness “hotspots.” Using data from a read-aloud task, our model analyzes the vo…
Prosodic features of polite speech
This paper uses interactional data to investigate the acoustic characteristics of polite or deferential speech in Korean. We asked fourteen Korean speakers to perform two tasks with two different interlocutors: a status superior and a friend. Consistent with previous studies of non-interactional data, deferential speech has lower pitch and shimmer, and quieter final syllables. However, divergent from previous studies, deferential speech featured …
Second Dialect Acquisition by North Korean Refugee Speakers
This study examined Korean three-way stop contrasts produced by North Korean (NK) immigrant speakers now living in South Korea, from the perspective of second dialect acquisition (SDA). Their production was compared with that of South Korean (SK) speakers. SK speakers and NK refugee speakers ( N = 22 each) completed three tasks designed to elicit careful and conversational speech: reading aloud lists of one-syllable words and short phrases and pa…
What do you learn from a single cue? Dimensional reweighting and cue reassociation from experience with a newly unreliable phonetic cue
In language comprehension, we use perceptual cues to infer meanings. Some of these cues reside on perceptual dimensions. For example, the difference between bear and pear is cued by a difference in voice onset time (VOT), which is a continuous perceptual dimension. The present paper asks whether, and when, experience with a single value on a dimension behaving unexpectedly is used by the learner to reweight the whole dimension. We show that learn…
Effects of L2 experience on Mandarin listeners’ perception of Korean politeness
Sounding like a father
Previous work on the Osaka dialect (OD) collectively suggests that this western regional variant of Japanese is associated with informality, masculinity, and affective fatherhood-social meanings that can be recruited in the construction of audio-visual media personas. This study examines the use of OD by one protagonist in the film Soshite chichi ni naru/Like father, like son, as well as the social meanings that listeners attribute to this variet…
Loudness Trumps Pitch in Politeness Judgments
Social meaning is not conveyed through words alone, but also through how words are produced phonetically. This paper investigates the role of loudness and pitch in determining the perception of politeness-related judgments in Korean. It has been proposed that high pitch is universally associated with polite or deferential social meanings. In contrast to this, Experiment 1 examined the perceptual effect of pitch and found no effect. Experiment 2 t…
Cross-cultural multimodal politeness
Pragmatic meanings are not only conveyed through words alone, but also through how words are produced phonetically. The current study investigated phonetic features that characterize the distinction between deferential and non-deferential speech style in Japanese. The Japanese data were then compared to previously published Korean data collected through the same methodology. The results revealed striking similarities between the two languages: De…
Acoustic Sources of Accent in Second Language Japanese Speech
This study reports an exploratory analysis of the acoustic characteristics of second language (L2) speech which give rise to the perception of a foreign accent. Japanese speech samples were collected from American English and Mandarin Chinese speakers ( n = 16 in each group) studying Japanese. The L2 participants and native speakers ( n = 10) provided speech samples modeling after six short sentences. Segmental (vowels and stops) and prosodic fea…

In Memoriam
Susan Guion Anderson (née Susan G. Guion) died just shy of her 45th birthday on 24th December 2011 in Springfield, Oregon, from an aggressive and rare form of cancer. Her early death cut short a very productive research career in second language phonetics, and deprived students of an extremely gifted teacher
Acoustic covariants of length contrast in Japanese stops
This study explores acoustic correlates to the singleton vs. geminate stop length contrast in Japanese. The proposal examined is that multiple acoustic features covary with the stop length distinction and that these features are available in the signal as potential secondary cues. The results support the proposal, revealing the presence of several acoustic features covarying with the singleton vs. geminate contrast in both durational and non-dura…
