Duration and voicing measures of voiceless plosives in Spanish
Description
A dataset containing measures of total duration and voiceless period duration
for instances of intervocalic Spanish /p/, /t/, and /k/. The data are taken
from 18 speakers in the task dialogues in the Spanish portion of the Glissando
Corpus (the speakers are university students in Valladolid, Spain).
