Description Usage Format References

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). If you analyze the ptk dataset in a publication, please cite Eager (2017) from the references section below.
