Many studies have investigated the temporal characteristics of the word-medial singletons and geminates in Indo-Aryan languages. However, little is known about the acoustic cues distinguishing between the word-medial singletons and geminates of Punjabi. The present study examines the temporal characteristics of Punjabi word-medial singleton and geminate stops in a C₁V₁C₂V₂ template. The results from five Punjabi speakers showed that, unlike previous studies of Indo-Aryan languages, the durations of C₂ and V₂ are the most important acoustic correlates of singleton and geminate stops in Punjabi. These findings therefore point towards the cross-linguistic differences in the acoustic correlates of singletons and geminates.
