F2 transition parameters including F2 onset and offset frequency and locus equations have been studied for Persian affricates, homorganic dental plosives /d, t/, and postalveolar fricatives. The F2 offset frequencies hierarchy is as follows: postalveolar fricatives > affricates > dental plosives. This parameter makes a significant difference among the mentioned consonants; however, it does not show a voiced-unvoiced contrast. F2 onset does not provide regular results, and locus equation coefficients do not show a significant difference between affricates and homorganic consonants.
