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. You can also save it in any other audio format you choose.Ĥ.Volume : IV, Issue : X, October - 2015 Normative Values of Adult’s Voice in Indian Population Using Praat Here are the steps:Ī) In the menu of the PRAAT Objects window, click SAVE then SAVE AS WAV file. If you want to keep your recording (i.e., save a copy to your hard drive), you need to SAVE it as a sound file. 3.0 Saving your recording as a sound file:ġ. Your sound file should now appear in the PRAAT Objects window. If you are done recording, you can click on SAVE TO LIST & CLOSE. When you are finished recording, click stop and save to list. Once you are ready to record, click the record button. Before you begin recording, be sure to give your recording a name that you will remember.ĥ. Under Input, be sure the correct input method is selected, either built-in microphone or whatever type of external microphone you have connected to your computer.Ĥ. Use the following settings: 1) under sampling rate choose 44,100 Hz and 2) select mono under the CHANNELS menu.ģ. Once you click on RECORD MONO SOUND, a popup window called SOUND RECORDER will appear. Also, stereophonic recordings take up a lot of space on your computer!Ģ. PRAAT also has the capability to record in stereo, but when it comes to gathering language data, mono files are preferred. In the menu bar of the Objects window, click NEW and RECORD MONO SOUND. As always, whenever you are recording your language consultants, it’s best to connect an external microphone to your computer, as opposed to using the internal mic. I also recommend some freeware software programs, such as Audacity and Cool Edit or Cool Edit Pro, that you can also use to make high quality recordings.
Using praat for voice analysis how to#
The video will give you a basic overview of how to do this and what settings you should use. In this video tutorial, you will learn how to make your own sound files using PRAAT. In Part 3 of this workshop, you will learn how to record using PRAAT.
