No PDF available ABSTRACT Tongue root advancement is reported to be an adjustment that facilitates phonetic voicing during stop closure (Westbury 1983). In a recent ultrasound study, Ahn (2018) reports that the tongue root is more advanced during the American English “voiced” stops than the “voiceless” stops even without actual phonetic voicing dur...

No PDF available ABSTRACT Tongue root advancement facilitates voicing during stop closure by enlarging the supralaryngeal cavity volume (Westbury, 1983). In a recent ultrasound study, Ahn (2018) reports that tongue is indeed more advanced during voiced than voiceless stops both in English and Brazilian Portuguese, suggesting that the articulatory a...

Previous research [7], showed that Mandarin speakers of English modified acoustic properties of their English speech as a factor of both the interlocutor (native vs. non-native speakers of English) and their own attitudes towards Mandarin and English. The present study investigates whether these acoustic modifications are perceptible to native spea...

Previous research (Dmitrieva et al., 2015) showed that Mandarin speakers of English modified acoustic properties of their English speech as a factor of both the interlocutor (native vs. non-native speakers of English) and their own attitudes towards Mandarin and English. The present study investigates whether these acoustic modifications are percep...
Article
Many languages make a two-way laryngeal contrast in obstruents, but the phonological and phonetic characterization of these contrasts continues to be controversial. In English, utterance-initial /b d ɡ/ stops are often phonetically voiceless. Languages like Brazilian Portuguese, however, exhibit phonetic voicing for /b d ɡ/ stops utterance-initiall...
Article
Articulatory adjustments are often necessary to ensure that closure voicing will be present in stops (Rothenberg 1968). One common adjustment is to enlarge the supralaryngeal cavity volume via tongue root advancement (Westbury 1983). This study uses ultrasound to examine tongue positioning during Brazilian Portuguese and Thai stops. Portuguese has...

We aimed to develop a word-reading test for Korean-speaking adults using irregularly pronounced words that would be useful for estimation of premorbid intelligence. A linguist who specialized in Korean phonology selected 94 words that have irregular relationship between orthography and phonology. Sixty cognitively normal elderly (CN) and 31 patient...
Article
Initiating or maintaining phonation during stop closure involves several adjustments, including tongue root advancement to enlarge oral cavity volume (Westbury 1983). Ultrasound imaging shows that in English, the tongue is more advanced for phonologically voiced stops, whether phonated or unphonated (Ahn 2015). The current study uses ultrasound to...
Article
Previous research on utterance-initial voiced stops in American English (AE) has shown that speakers enlarge the vocal cavity via tongue root advancement whether or not the stop is phonated when compared to voiceless stops (Ahn 2015). The current ultrasound study expands this line of research to examine two further variables: (a) utterance-initial...
Article
This paper reports on a nonce word study of imperfect overlapping in Korean blends where speakers rated blends with various pairs of segments in a possible overlapping position (e.g. kata+pami = katami). The results show that Korean speakers prefer blends with segments with a laryngeal feature difference (/p/ vs. /ph/) as overlapping segments in co...
Article
In English, phonologically voiced consonants are often phonetically voiceless in utterance-initial position. Other than Westbury (1983), there is little articulatory evidence regarding utterance-initial voicing in American English. The current study uses ultrasound imaging and acoustic measures to examine how tongue position correlates with phonati...

Article
This study addresses the question of what basic principles and constraints govern blending while focusing on the description and analysis of phonological properties of Korean blends. Korean blending shows a systematic phonological word-formation process that usually preserves the prosodic structure of the head source word, while the initial part of...
