Prosodic-structural modulation of stop voicing contrast along the VOT continuum in trochaic and iambic words in American English

Stop voicing contrast in American English: Data of individual speakers in trochaic and iambic words in different prosodic structural contexts

“…The data presented in this article illustrate eleven American English speaker’s individual patterns of the acoustic phonetic realization of the voiced and voiceless stop consonants (/p/ - /b/; /t/ - /d/) in various prosodic contexts, which is related to Kim et al [1] .…”

“…Six female and five male American English speakers in their 20s and early 30s were paid to participate in the acoustic recording (See [1] for more information about the speakers).…”

“…As shown in Table 2 , eight words were used as test words. Half of the words were stress-initial words (trochaic) and the other half were stress-final (iambic), so that the first syllables were stressed vs. unstressed (See [1] for more information about the speech materials).…”

“…The IVI was defined as a combined sum of VOT (as a positive value) and Voicing-in-Closure (as a negative value). This voicing index was devised to weigh the relative contribution of VOT and Voicing-in-Closure to the voicing contrast, allowing us to assess the phonetic voicing of both voiceless and voiced stops along a single integrated dimension of the phonetic voicing (See Kim et al [1] for further discussion of the usefulness of this metric).…”

Structured heterogeneity in Scottish stops over the twentieth century

“…Rather than redefining VOT in a way that would give these tokens negative values (e.g. Abramson & Whalen 2017), we defined VOT as a strictly positive measure-similarly to Davidson (2016) and Kim et al (2018)-because this gave us greater flexibility to describe laryngeal timing for the Scottish stop contrast. We could measure (positive) VOT for all stops and have this be an independent dimension to 'voicing', which we examined through the degree of VDC (see Cho et al 2019).…”
