Abstract

The data reported in this article contain eleven (6 female and 5 male) individual speaker’s speech production patterns for the word-initial voiced and voiceless stops (/p,t/ and /b,d/) in American English. The production patterns are documented in the acoustic parameter: the Integrated Voicing Index (IVI) obtained from Voice Onset Time (VOT) and voicing duration in the stop closure (Voicing-in-Closure), in various prosodic contexts: lexically-stressed vs. unstressed; accented (focused) vs. unaccented (unfocused); phrase-initial vs. phrase-medial. The data also contain a CVS file with each speaker׳s mean values of the IVI, VOT and Voicing-in-Closure for each prosodic condition for the voiced and voiceless stops, along with the information about the speaker gender. For further discussion of the data, please refer to the full length article entitled “Prosodic-structural modulation of stop voicing contrast along the VOT continuum in trochaic and iambic words in American English” (Kim et al., 2018).

Linguistics Phonetics Table, figure, spreadsheet Acoustic measurements based on speech recorded in a laboratory setting Tables, figures, CVS file Three main experimental factors were included such as stop voicing, stress, accent, and prosodic boundary
The data can be used to examine the gender-related difference in the production of the voiced vs. voiceless stops in American English

Summary

Initial stops in the trochaic words: in the stressed condition

This provides the information of how the phonological voicing contrast in the stressed initial syllable is phonetically implemented along the phonetic voicing dimension: the IVI, the Integrated Voicing Index which was obtained from VOT and Voicing-in-Closure (Fig. 1a) (see below for more information about the IVI).
