Phonological specifications for onset, nucleus and offset for 1697 Dutch monomorphemic words with a final obstruent. These final obstruents may exhibit a voicing alternation that is traditionally described as syllable-final devoicing: underlying /d/ in /hond/ becomes a /t/ when syllable-final ([hOnt]) and remains a /d/ otherwise ([hOn-den]).
A data frame with 1697 observations on the following 9 variables.
a factor with the words as levels.
a factor for the first consonant in the onset, with levels
a factor for the second consonant in the onset, with levels
a factor describing the vowel with levels
a factor for the first consonant in the offset, with levels
a factor describing place and manner of articulation of the final obstruent,
T (/t,d/) and
a numeric vector for the number of syllables in the word.
a factor with levels
F (final) and
a factor with levels
