Establishment of Acoustic Norms for PRAAT Software in 20-25 Year Old Indian Adults

Abstract

PRAAT Software has very few norms in Indian population; especially in adult population has not been established. The present study was aimed to establish PRAAT norms for the adults in the age range of 20 - 25 years. A total of 180 subjects were selected which included 90 males and 90 females. A voice sample was taken for the production of /a/, /i/ & /u/. Voice parameters such as mean pitch, Jitter, Shimmer & HNR were assessed. Result showed significant difference between both genders and age groups for all voice parameters. Very less sample size & limited parameters were considered hence that will be the Limitations of the study. Future studies can be done on other adult groups particularly on geriatric group with other voice parameters on consideration.
