What´s a tune?What´s a tune?• Sequence of static tones (cf. AM model,
Pierrehumbert,1980) or contour elements (KIM, Kohler, 1991)
- No structural (only semantic) restrictions for combinations of pitch accents + edge components
- For pitch accents: nuclear = prenuclearIntroduction

Summary & Conclusion
• Compositionality -> Intonational meaning given by the independent contribution of individual tones (Pierrehumbert & Hirschberg, 1990, inter alia)
H* L- L%+ + = Statement
L* H- H%+ + = Yes/No question
Tunes Sentence mode
‘Nucleus’ (nuclear accent + terminal edgecomponents) essential in conveying meaning

Q/S in GermanQ/S in German• Also questions with declarative syntax are possible:
• In such cases the intonation is crucial, i.e. It MUST be raising. Isacenko & Schädlich (1970): “If an utterance contains no other syntactic or lexical cue to identify it as a question […] then only the last […] rising tone-switch provides the necessary information to allow the hearer to identify it as a question" (p.32) (Cf. also Huddleston (1994) for English and Haeseryn et al. (1997) for Dutch)
=> known as ‘intonation question’ or ‘queclarativ’ (Sadock 1974)

• Overall significant difference in responses between (1)-(2)-(3) vs. (4)-(5) base types for both short and long stimuli

Summary & Conclusion
The intonational signalling of pragmatic functions of sentences in German is not bound to the “nucleus” and the subsequent final F0 pattern:
1. Questioning vs. assertive sentences are well discriminable when only the prenuclear accent region is left in the stimulus
This cannot depend on the phonological specification of the prenuclear accent -(H)* for the 5 intonation types- though phonetic factors such as speech rate or intensity might have affected listeners’ judgements

2. Contrast in listeners’ judgement for stimuli (1)-(2)-(3)vs. (4)-(5) already in the “short” condition This might be due to the differences in the alignment of the prenuclear rise and/or the shape of the fall between the two intonation groups

Stimuli with patterns (5), ie. containing a terminal fall but preceded by a late rise-fall/concave fall, shifted the judgements towards more “astonished”, “uncertain” and “questioning”

Summary & Conclusion
Stimuli with patterns (5), ie. containing a terminal fall but preceded by a late rise-fall/concave fall, shifted the judgements towards more “astonished”, “uncertain” and “questioning”
4. The perception of intonation modality is improved when the nucleus is also available, especially in ‘questioning’ stimuli (4)-(5)
This suggests that prosodic cues in the prenuclear region are less stronger for Q than for S modality, so that listeners have to rely more on the nuclear pattern when perceiving Q (see also Petrone & D’Imperio, 2008 for Neapolitan)

Summary & Conclusion
German listeners exploit the F0 prenuclear region forQ/S perception, even in absence of a clear informationfrom the ‘nucleus’:
1. Alignment and dynamic cues distributed in the prenuclear F0 region seems to be at work when perceiving the Q/S contrast in GermanThe early fall alignment is a robust cue for ‘astonished statements’ perception. The late fall alignment is more ambiguous, and additional differences in the shape of the fall become crucial for ‘question’ perception.

2. The fall alignment/shape manipulation affected listeners’ judgment only when the prenuclear rise is earlyThis can be due to our manipulation: the shift from the early to the late alignment could have been too “far”. The shape difference is more salient when the rise is earlier

3. The base stimulus produce a small but significant
effect. This means that cues other than F0 (voice quality, speech rate, etc.) might have been exploited by listeners

• The influence of the prenuclear F0 region is accounted for by the interaction of multiple F0 dimensions (alignment, shape), thus suggesting that dynamic properties might help in interpreting linguistic information
• Our results suggest that intonation meaning is defined by the contour as a whole : the interrelation between tones in a tune cannot be captured by a strict compositional approach
