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
