Sataloff RT, Benninger MS (eds) (2016) Sataloff’s comprehensive textbook of otolaryngology: head and neck surgery (laryngology), vol 4. Patients who are with dysphonic voices due to laryngeal pathologies had altered values of acoustic parameters compared to normophonic adults and clinicians can precisely differentiate pathological voices from normophonics. There are no gender differences in adult healthy voices except fundamental frequency (F0), which is higher in females. This study establishes normative acoustic voice parameters in normal healthy adults.
#Praat air services software#
Objective voice analysis by using Praat software is convenient, reliable and cost effective method.
Pathological voices of case group subjects with laryngeal pathologies had statistically significant higher values of jitter local (%), shimmer local (%) and lower values of HNR as compare to normal healthy voices of control group. There were statistically significant higher values of fundamental frequency (F0) in females, while jitter local (%), shimmer local (%) and harmonic to noise ratio (HNR) had no gender differences in normal healthy voices. Voice samples of vowels /a/, /i/ and /u/ of 80 normal healthy adults (males = 40, females = 40) of control group and 40 patients with dysphonic voice of case group collected and acoustic voice parameters were extracted by using Praat software. The present study was undertaken to standardize acoustic voice parameters in normal healthy adult individuals and gender comparison among them and also acoustic voice analysis of pathological voices and it’s comparison with normal healthy voices. Acoustic voice analysis is still a valuable technique which enables voice clinicians to compare voices to differentiate them into normal and abnormal.
