The aim of this study was to determine if Dutch speakers
reliably signal phrase-internal lexical boundaries, and if so, how. Six speakers recorded 4 pairs of phonemically identical strong-weak-strong (SWS) strings with matching syllable boundaries but mismatching intended word boundaries (e.g. reis # pastei versus reispas # tij, or more broadly
C1V2(C)#C2V2(C)C3V3(C) vs. C1V2(C)C2V2(C)#C3V3(C)).
An Analysis of Variance revealed 3 acoustic parameters that
were significantly greater in S#WS items (C2 DURATION, RIME1
DURATION, C3 BURST AMPLITUDE) and 5 parameters that were
significantly greater in the SW#S items (C2 VOT, C3 DURATION, RIME2 DURATION, RIME3 DURATION, and V2 AMPLITUDE).
Additionally, center of gravity measurements suggested that
the [s] to [t] coarticulation was greater in reis # pa[st]ei
versus reispa[s] # [t]ij. Finally, a Logistic Regression
Analysis revealed that the 3 parameters (RIME1 DURATION,
RIME2 DURATION, and C3 DURATION) contributed most reliably
to a S#WS versus SW#S classification.
