Objectives: This investigation aimed to compare the performance of two software packages,
namely “Computerized Scoring of the Stuttering Severity (CSSS)” and “Praat,” in calculating
the mean duration of stuttered syllables.
Methods: In this descriptive-analytical study, 35 eligible stuttering subjects (26 male and
9 female), aged between 18 and 42 (m=26.23±6.02) were selected via the non-probability
sampling method to enter the study. Spontaneous speech samples of subjects with stuttering
were recorded with the help of a video camera. Two separate tasks were used to calculate the
Mean Duration of the Three Longest Stuttering Events (MDTLSE) by applying the second
version of the CSSS software and the 5.3.78 version of the Praat software. In the first task,
MDTLSE was measured 10 times for a subject with mild stuttering and a subject with severe
stuttering. In the second task, MDTLSE was measured just one time for each stuttering
participant, and comparison was performed by paired t-test using the SPSS Version 22.0
computer software.
Results: In the first task, in which Praat and CSSS-2 were used for the calculation of MDTLSE
(10 times), the minimum and maximum obtained values were found to differ by 0.007 seconds
(7 milliseconds) and 0.2 seconds (200 milliseconds), respectively. In the second task, in which
MDTLSE was calculated with the software CSSS-2 and Praat, the differences were 2.34±2.17
and 3.02±2.98, respectively, that were found to be statistically significant (P=0.025).
Discussion: Higher reliability and replicability of duration values calculated by Praat software
indicates that this software can be applied for more precise determination of duration of
stuttered syllables.

Two separate tasks were used to calculate the Mean Duration of the Three Longest Stuttering Events (MDTLSE) by applying the second version of the CSSS software and the 5.
In the second task, MDTLSE was measured just one time for each stuttering participant, and comparison was performed by paired t-test using the SPSS Version 22.
In both ver- sions of the SSI, the overall severity score of stuttering is measured by combining the scores of percentages of Stuttered Syllables (%SS), Mean Duration of the Three Longest Stuttering Events (MDTLSE), and Physical Concomitants (PC), which are the face and body move- ments made during speech sampling of the subjects.
The pres- ent study was aimed to examine the similarities and dif- ferences in the mean duration of stuttered syllables as obtained by CSSS-2 and Praat so as to determine wheth- er these two different tools provide the clinician with the same values or not.
Values ob- tained by 10 times measurement of MDTLSE with Praat and CSSS-2 are reported in Table 2 for one participant with mild stuttering and one with sever stuttering.
Praat and CSSS-2 measurement of MDTLSE (10 times) for a subject with severe stuttering yielded values ranging from 6.
