Abstract

Arguments for phonological analyses can be internal or external. Among the most highly prized external arguments are experimental data on speech behaviour. Boundaries of intonational phrases need not obviously be marked by pauses. Our expectation in situations in which they are not is that they are marked by a boundary tone, such as H%, to signal the separation between the preceding and the following portion of speech. The boundary tone will cause some characteristic change in the pitch contour at the location of the boundary. An example is the peak caused by a final H% in (1).

(1)          Ze zit VAST met dat ding op de SNELweg

            ‘She has got stuck with that vehicle on the motorway’

            or ‘She must be on the motorway with the vehicle’

A closer look at data from Dutch suggests that the above generalization is often true, but that there are exceptions either way. First, a low valley immediately after an accent peak does not induce a boundary after VAST in (2). Second, absence of a clear pitch movement nevertheless results in a boundary after ding in (3).

(2)            Ze zit VAST met dat ding op de SNELweg

(3)            Ze zit VAST met dat ding op de SNELweg

Where (1) is ambiguous, due to the interpretation of vast as an adjective ‘stuck’ or as an adverb ‘therefore probably’, (2) means ‘She has got stuck with that vehicle on the motorway’, while (3) means ‘So she must be on the motorway with that vehicle’. The adjectival meaning of vast is best triggered by the presence of a boundary and identity of pitch accents in the two intonational phrases. The adverbial meaning is most likely to be triggered by the absence of an intonational boundary.

We designed an experiment with artificial two-accent intonation contours having identical pitch accents in the two positions. We varied the length of the first phrase (2), the presence of the medial boundary (2), and the type of pitch accent (3). Source sentences were

 

(4) Ze zit vast met dat ding op de snelweg          ‘She has got stuck (with that vehicle) on the                                                                               motorway’

     Ze zit vast op de snelweg                              or ‘She must be on the motorway (with that                                                                               vehicle)’

    Hij zit alleen met die man in ’t café                 ‘He is alone (with that man) in the pub’ or

    Hij zit alleen in ’t café                                   ‘The problem is he’s (with that man) in the pub’

The presence or absence of the contours is determined on the basis of ToDI transcription. The results will be argued to support the analysis underlying that transcription system.
