With any measurement, Praat is likely to give you a very exact number. Click "Save to list & Close" to load the recording into the Object list.If you continue to get some red bars, just continue with the assignment, but know that you may have to re-record the sound if you're having trouble measuring things. If you get red bars, click "Stop", adjust the microphone, and try again. Also make sure you have the microphone far enough away from your mouth that you don't get red bars during the recording. Make sure you speak clearly and not too quietly. Clicking "Record" again will replace your last recording with a new one. Enter a name for the recording in "name".In Praat, click "New" > "Record mono Sound.".The built-in mics in most computers should also be okay, though these vary a lot-Macs at least seem to have consistently decent built-in microphones. Video conferencing or gaming headsets will usually work great. I recommend using an external headphone and microphone. Most computers on campus seem to have it installed already, but since it doesn't have to be installed, you can just download it and run it on any computer (even if you don't have admin rights on it). To use Praat on your own computer, you can download it from its website, at. t–test was carried out to find the significant parameter to distinguish between sounds across genders.Basic guide to using Praat for acoustic phonetic analysis Setting up your "lab" Mean and standard deviation were analyzed separately for males and females. The voice of the individuals with a variety of variables was extracted using PRAAT software version 5.3.17. Results and Discussion This study was undertaken to investigate the acoustic parameters in the normal individual’s voice. Following parameters were analyzed f0 ( fundamental frequency), Jitter (local), jitter (local, absolute), shimmer (local), shimmer (local dB), HNR (harmonics to noise ratio), f1 ( first formant frequency), f2 (second formant frequency), and f3 (third formant frequency). Phonation of 4–5sec of duration and sampling frequency of 44100Hz with less amplitude fluctuation was taken into consideration for recording. Here subjects were instructed to take a deep eath and phonate /a, i, u/ as long as possible. While recording environmental disturbances (sound treated room), microphone to subject distance and seating comfortability of subject was taken into consideration. Recording was done using microphone attached to a laptop having praat software version (5.3.17). ![]() Criterion of selection was no voice abnormalities in terms of anatomy and physiology. To compare gender difference on voice parameters Methodology A total of 60 normal subjects were selected which included 30 females and 30 males.To develop normative data of adult’s voice.The vocal fold viation of female is around 200 – 220/s and 100 – 120/s for men. Voice production depends upon coordination of these fundamental systems i.e., respiratory, phonatory, resonatory and regulatory. Loudness is psychological correlate of intensity, while quality determines the character or distinctive aspect of voice. Pitch is a psychological correlate of frequency, which varies across gender, as females have high and males have low pitch. Components of voice are pitch, loudness and quality. This is generated by the help of air flow from the lungs and Bernoulli effect which results in opening and closing of vocal folds. Voice also depicts an individual’s health condition, mood and overall personality. Introduction Voice is a modality through which most of the living things like humans produces speech, expresses different emotions. Significant differences were noticed on some of the voice parameters between genders. Mean and standard deviation were calculated and also t–test was carried out to observe the significant difference across gender on voice parameters. Voice parameters were analyzed like fundamental frequency( f0), Jitter (local), jitter (local, absolute), shimmer (local), shimmer (local dB), harmonics to noise ratio(HNR), first formant frequency( f1), second formant frequency( f2), and third formant frequency( f3) for the vowels /a/, /i/, and /u/. The voice samples were recorded in sound treated room and analyzed with praat software. The present study included 60 voice samples (30 males and 30 females) age range 18 to 25 years. Any deviation from these guidelines is considered as voice disorder. Voice characteristics convey information not only related to the individuals laryngeal status but also the social origins, emotional state, physique, age and sex. Voice plays a major role in speech and communication. ![]() Volume : IV, Issue : X, October - 2015 Normative Values of Adult’s Voice in Indian Population Using Praat
