Durational Cues Boundary cues

Signaling the presence of a boundary

Hierarchy cues Signaling the strength of a boundary

Boundary cues in Taiwan Mandarin

Final lengthening

As in English, Japanese, Mainland Mandarin

Penultimate lengthening Only in Mandarin

A feature oftonelanguages?

Hierarchy cues in Taiwan Mandarin

Pause duration

As in English, Japanese, Mainland Mandarin

Pre-boundary syllable duration Negative hierarchy effect NOT in Mainland Mandarin Local

Taiwan Southern Min (Taiwanese)

A tone language

Speaker generations:

Degree of influence between Min & Mandarin Old: Min monolinguals Young: simultaneous bilinguals, better in Mandarin

Age difference Direction of change/influence

Explaining penultimate lengthening

Tone languages (Mandarin, Taiwanese)

Dense stress assignment Lacking dura=onal variability

Larger domain of lengthening as compensation

Preference for the disyllabic word template

Disyllabic word types are dominant in Mandarin andTaiwanese (Ministry of Education, 2010; Tseng, 2004; Duanmu, 1999)

Hierarchy cues

Negative hierarchy effect on the pre-boundary

syllable In the IP+pause condition Same as in Taiwan Mandarin (Fon, 2002; Fon et al., 2011)

Highlighting pauses?

Pause duration as a robust hierarchy cue Production: Mandarin (Fon, 2002; Fon et al., 2011) , Taiwanese (this study) Perception: Mandarin (Lin & Fon, 2009)

Research questions revisited

On boundary cues:

Does Taiwanese have penultimate lengthening?

On hierarchy cues: Is there the negative hierarchy effect in Taiwanese?

Are there age differences?

34

YES!

YES!

NO!

Conclusion

Penultimate lengthening as a boundary cue

For tone languages (Mandarin, Taiwanese) Word template as another possibility

Hierarchy cues in Taiwanese and TaiwanMandarin

Similar strategy: negative hierarchy effect
