Professor Taehong Cho's research lab specializes in the phonetics-prosody interface, focusing on how prosodic structure—such as accent, prosodic boundaries, and morphological structure—influences the articulatory and acoustic realization of speech. The lab employs advanced articulatory phonetics methods, including electromagnetic articulography (EMA) and electropalatography (EPG), to investigate the dynamic interplay between phonological structure and motor planning in speech production. Key research directions include prosodic strengthening, intergestural timing, coarticulation, and the role of prosody in shaping vowel and consonant features across languages.

In this study the effects of accent and prosodic boundaries on the production of English vowels (/a,i/), by concurrently examining acoustic vowel formants and articulatory maxima of the tongue, jaw, and lips obtained with EMA (Electromagnetic Articulography) are investigated. The results demonstrate that prosodic strengthening (due to accent and/or prosodic boundaries) has differential effects depending on the source of prominence (in accented syllables versus at edges of prosodic domains; domai
This paper examines the effects of morpheme boundaries on intergestural timing, and demonstrates that low-level phonetic realization is influenced by morphological structure, i.e. compounding and affixation. It reports two experiments, one using electromagnetic midsagittal articulography (EMA) and one electropalatography (EPG), examining Korean data. The results of the EMA study show that intergestural timing is less variable for adjacent gestures across the word boundary inside a lexicalized co
Abstract Prosodic structure has been assumed to serve as a frame for articulation, so that phonetic shaping of abstract phonological representations is fine‐tuned as a function of the prosodic system of the language. The intricate relationship between phonetics and prosodic structure has been explored in the literature under the rubric of the phonetics–prosody interface. This paper reviews various aspects of the phonetics–prosody interface and discusses how prosodic structure modulates phonetic
In this special collection entitled <i>Marking 50 Years of Research on Voice Onset Time and the Voicing Contrast in the World's Languages</i>, we have compiled eleven studies investigating the voicing contrast in 19 languages. The collection provides extensive data obtained from 270 speakers across those languages, examining VOT and other acoustic, aerodynamic and articulatory measures. The languages studied may be divided into four groups: 'aspirating' languages with a two-way contrast (English

This study explores the relationship between prosodic strengthening and linguistic contrasts in English by examining temporal realization of nasals (N-duration) in CVN# and #NVC, and their coarticulatory influence on vowels (V-nasalization). Results show that different sources of prosodic strengthening bring about different types of linguistic contrasts. Prominence enhances the consonant׳s [nasality] as reflected in an elongation of N-duration, but it enhances the vowel׳s [orality] (rather than
