Voicing Assimilation in Stop Sequences in Catalan and English

Nestor Cuartero

Universitat Autònoma de Barcelona, Spain

The aim of the experiment was to determine the direction and temporal extent of voice assimilation in Catalan and English VOICELESS-VOICED stop sequences, and the effect of speaking rate on the process. The material consisted of two-word sequences that contained consecutive stops across word boundaries. The results showed that, in Catalan, C1 was realized as voiced when followed by a voiced stop. In English, on the other hand, C1 was implemented with no vocal fold vibration, and C2 was devoiced. The results also showed that, in Catalan, the process applied in a categorical fashion, so that the closure for C1 was implemented as voiced. English exhibited variability in the degree of voicing during the closure of C2. Degree of voicing in C1 did not co-vary with speaking rate in Catalan, and C1 was voiced independent of speaking rate. In English, there was no effect of speech rate, either.
