This study investigated nasalization process from final nasal to initial voiced stops across intermediate phrase boundary, word boundary, tone group boundary, and syllabic boundary in Taiwanese. The degree of nasalization was investigated with nasal airflow data collected from four native Taiwanese speakers producing sentences with final nasal at the end of second syllable and initial voiced stops at the third syllable. Results showed that the peak nasal airflow across intermediate phrase boundary was the earliest in time for all four subjects, and the highest in amplitude for subject HFY and HYH. The amplitude of peak nasal airflow across tone group boundary was stronger than that across syllabic boundary. In fact the nasal peak across tone group boundary was the highest for CYS and LYK. The location of peak nasal airflow across word boundary showed a speaker depend pattern. The influence of tone group boundary to the occurrence of peak nasal airflow is more consistent than word boundary.
