Stress is known to be an important prosodic feature of speech. The recognition of stressed speech has always been an important issue for speech researchers. On the other hand, providing a large corpus with the coverage of all different stressed conditions in a certain language is a difficult task. Farsi (Persian) has been no exception to this. In this research, our aim has been to evaluate the effect of stress on prosodic features of Farsi language, such as phoneme duration, pitch frequency and the pitch contour slope. These might be valuable in further research in speech recognition. As the main influence of stress is on vowels, the effect of stress on such parameters as duration and pitch frequency and its slope on the phoneme level and for vowels has been evaluated.
