Word informativity influences acoustic duration: Effects of contextual predictability on lexical representation
This study investigates whether speakers have a context-independent bias to reduce low-informativity words, which are usually predictable and therefore usually reduced, and supports representational models in which reduction is stored, and where sufficiently frequent reduction biases later production.

Acoustic differences in morphologically-distinct homophones
The result suggests that wordforms influence production of their relatives, and stem and suffix durations are significantly longer in fricative-final inflected words compared to their simple counterparts (freeze, lapse), while there is a null effect for stop-final words. Expand
Coda glottalization in American English
Results indicate that coda glottalization is more common before a sonorant, and this effect is still found phrasefinally, even when phrasal creak is taken into account. Expand
Acoustic Differences Between English /t/ Glottalization and Phrasal Creak
The results indicate that the discriminant functions can classify these sources of creaky voice above chance, and that Cepstral Peak Prominence, a measure of harmonics-to-noise ratio, is important for distinguishing phrasal creak from glottalization. Expand
Dynamic hyperarticulation of coda voicing contrasts.
The results indicate that talkers enhance the durational cues associated with the word-final voicing contrast based on whether the context requires it, and that this can involve both elongation as well as shortening, depending on what enhances the contextually-relevant contrast. Expand
Plosive voicing acoustics and voice quality in Yerevan Armenian
Yerevan Armenian has breathy-voiced plosives which are produced with closure voicing and a relatively spread glottis that is maintained into a following vowel, which supports a historical analysis in which early Armenian voiced stops were also breathy, rather than plain voiced. Expand
Contextual and morphological effects in speech production
Author(s): Seyfarth, Scott James | Advisor(s): Ackerman, Farrell; Garellek, Marc | Abstract: A native speaker knows how to produce an unlimited number of words and possible words in their language,Expand
Physical and phonological causes of coda /t/ glottalization in the mainstream American English of central Ohio
In American English, a glottal stop is sometimes pronounced in place of an expected syllable coda /t/, and audible glottalization is attested before both /t/ and /p/ in coda position. FollowingExpand
Communicating with Cost-based Implicature: a Game-Theoretic Approach to Ambiguity
Two studies are reported in which pairs of speakers show alignment of their use of ambiguous forms based on this kind of shared knowledge, extending the analysis of cost-based pragmatic inferencing beyond that previously associated only with fixed lexical hosts. Expand
