In a previous production experiment, post-focus compression (PFC) of F0 and intensity were found to be present in Persian. It was also shown that F0 and duration were the main correlates of prosodic focus in Persian. However, the perceptual relevance of PFC in Persian was not yet clear. The present paper reports the findings of an experiment on focus perception in Persian. Native speakers of Persian listened to sentences produced with focus in different positions as well as the neutral-focus sentence, and judged the presence and location of focus. Results show that final focus is identified much less well than other types of focus, and most of its confusion is with neutral focus. This shows that the presence of PFC is a main factor in recognizing prosodic focus in Persian.
