The present study aimed to investigate the effect of speech sample duration, the person is a habitual pitch.
Methods: In the present study, no natural base frequency of 30 female speech sound disorder, aged 18 to 30 years using praat were using a counting task in 60 seconds - that's three times and then averaged in -, was obtained. Participants also must have to fulfill the inclusion criteria of the study.  
Results: The mean baseline frequency words ranged 0-1 seconds: 218.87± 19.22, in the range 0-5 seconds, 211.00± 19.56, in the range 0-15 seconds, 202.65± 19.50, 219.07± 105.49 in the range 0-30 seconds. in the range of 0-60 seconds when it was 215.86± 103.33. Repeated measures ANOVA showed a statistically significant relationship (s) has base frequency speech range (p&ge 0.001 F=47.136).
