This study examines the phonetic correlates of stress and accent in Catalan, analyzing
syllable duration, spectral balance, vowel quality, and overall intensity in two
stress [stressed, unstressed] and in two accent conditions [accented, unaccented].
Catalan reveals systematic phonetic differences between accent and stress, consistent
with previous work on Dutch, English, and Spanish (Slujter & van Heuven
1996a, 1996b; Campbell & Beckman 1997, Ortega-Llebaría & Prieto 2006). Duration,
spectral balance, and vowel quality are reliable acoustic correlates of stress,
while accent is acoustically marked by overall intensity and pitch. Duration, at least
in Catalan, is not a reliable indicator of accent since accentual lengthening was
found only in speakers who produced some accents with a wider pitch range.
