Phrase-final intonation adjustment in Lebanese Arabic

Intonation languages such as English and German have been described as having, among others, ‘realizational’ differences with regard to their intonation (Ladd 1996). One such difference is whether phrase-final pitch contours that lack sufficient segmental material to be realized naturally are subjected to truncation or compression. The current investigation examines this question in Lebanese Arabic. Stimuli were created with decreasing segmental material (disyllabic phrase-final, monosyllabic phrase-final) for both statements and questions. The contours produced by 16 speakers consisted of rises (questions) and rise-falls (statements). Results indicate that reducing the segmental material induces compression in rises and truncation in rise-falls, supporting the claim that languages cannot simply be divided into compressing versus truncating languages, and that the shape of the intonational contour plays a role in accommodation strategies. Speaker variation is also discussed.
