Quantity vs Durational Enhancement of Tone in the Maastricht Vowel System

Duration measurements of long and short high vowels in the Limburgish dialect of Maastricht show that these vowels have a relatively contextfree durational difference compared to the durational difference found between members of tonal minimal pairs in the dialect. The latter have a substantial duration difference in intonation-phrase final position, but a much reduced difference in phrase-internal positions. These data support the position that the high vowels contrast for quantity, not for tone.
