The Prosody of Wh-exclamatives and Wh-questions in German: Speech Act Differences, Information Structure, and Sex of Speaker

Abstract

The prosody of non-assertive speech acts other than questions is rather underexplored. Very little is known about the role of information structure in non-assertive speech acts in general. The present study presents two production experiments examining the prosody of string-identical verb-second (experiment 1) and verb-final (experiment 2) wh-exclamatives and wh-questions in German in relation to their status as different speech acts, in relation to their sensitivity to information structure, and in relation to speaker sex. The study shows that the two speech acts are differentiated by many prosodic means, both globally (duration, intonation contour) and locally (accent distribution in the clause-initial and clause-final regions; pitch, duration, intensity on various elements in the clause, especially the subject pronoun and the direct object, which are more prominent in exclamatives, and the verb-second auxiliary, which is more prominent in questions). Exclamatives overall show a very rigid prosodic contour; they typically are realized with an accent on the subject pronoun and on the object and end in a fall. Questions are much more flexible; they are realized as rises or falls, and show a more varied accent structure in the clause-initial and clause-final regions. Both speech acts show information-structural effects of givenness marking, but the effects in exclamatives are remarkably weak. It is proposed that the speech-act marking prosody overrides information-structural effects to some extent. Male and female speakers show differences in their preferred accent patterns for the two speech acts. Some acoustic differences are only reliable for female speakers.
