Conclusionīefore implementing these norms in clinical set up we must consider that these values are developed for the adults whose L1 is Nepali language and the software used for the establishment of norms was Praat.ĭawadee P et al (2016) Wordlist in Nepali to assess articulatory errors. However, the females had greater F0, jitter, RAP, PPQ5, shimmer, APQ11 than the males. Mann–Whitney test revealed there was a highly significant difference in all the parameters taken for the study among males and females. PRAAT software was used to extract the acoustic parameter of voice mean pitch, Jitter, RAP, PPQ 5, Shimmer, and APQ 11. Sustained phonation of five short vowels /a/, /i/, /o/, /u/ and /e/ were used in order to measure the acoustic variables. MethodologyĪ total of 50 Nepali students, 25 males and 25 females of the age range 18 to 25 years with no history of voice disorders, flu, neurological disorders, speech, language impairment, and respiratory dysfunction were included in the study. The acoustic measurement of the severity of the symptoms present in pathological voice is an active research area, for being inexpensive and non invasive. Vowels are differentiated based on acoustic characteristics. The speech signals consist of strings of vowels and consonants. ![]() Speech production is the most unique task performed by a human.
