Grunts and you may strong grunts both incorporate repeated facets. Mainly because repeated elements differed more on a couple of grunt brands, we titled him or her in a different way: ‘pulses’ to own grunts, and you will ‘sound cycles’ to have strong grunts. We used the program PRAAT 5.cuatro.01 () towards voice analyses.

We picked higher-quality grunts and you can strong grunts of the only as well as those in new research out of voice attributes, that had a rule-to-audio proportion out-of dos or even more towards the around three pulses/sound time periods into highest amplitude. To do so, we compared this new voice tension of your own heartbeat/years on 3rd higher amplitude towards voice tension of three at random chosen circumstances on the record noise within 0.5 s before the grunt or strong grunt. In the event the voice tension of that heart circulation/period was at the very least twice as high because the record noises, i analysed this new services of your own grunt otherwise deep grunt. Into the investigation of one’s characteristics of your own grunt products, we noticed four variables: step one. level of pulses/time periods each voice, dos. time of this new sound, step three. level of pulses/cycles for each and every next, cuatro. prominent volume.

In order to measure what number of pulses/time periods for every single sound, i marked most of the evident heart circulation/duration on wave form of each and every grunt at the no crossing pursuing the large height throughout the pulse/stage and mentioned the new noted bicupid-quizzen zero crossings. To select the time of a sound, i mentioned committed within marked zero crossings of your basic and you will history noticeable pulse/cylcle. In order to calculate the number of pulses/time periods per second, i separated what number of pulses/cycles by time of the brand new voice. To determine the prominent regularity, i examined the three loudest pulses in this a sound towards regularity towards the high voice force and you will grabbed the typical of these three frequencies.

With the analysis of voice services having ticks and you may plops, we simply utilized musical for which we could obviously choose the brand new sound-producing fish. We discussed ticks and you may plops using a couple variables: step 1. Principal volume, dos. voice pressure level difference between down and better wavelengths.

To choose the prominent volume of your own sound, i investigated the power spectrum of the new mouse click or plop to possess the volume towards the high voice stress. I derived the power range about zero crossing of your own waveform involving the highest and you will lower amplitude. So you can assess this new voice pressure differences, we substracted the latest voice pressure of your 5th harmonic regarding this new voice pressure of dominating volume.

Comparison away from voice attributes

Into the reviews out-of sound attributes, we first averaged the information to own men audio for the personal top. We had been not able to do this for women, because there are no way off a couple of times identifying personal people into the new videos easily.

To own presses and plops, i very first tested to have intercourse-certain variations of one’s analysed features

We opposed the brand new dominating volume and you will period anywhere between male grunts and you may strong grunts to determine differences between the 2 telephone call items. I up coming checked out for differences when considering the latest each other version of single-heart circulation tunes.

For statistical analyses, we first investigated the properties of the tested sounds for normality using Shapiro-Wilk tests. If data were normally distributed according to Shapiro–Wilk test (P > 0.05), we used t-tests to examine the differences in sound properties. If the Shapiro–Wilk test showed a significant deviation from a normal distribution (P < 0.05), we log-transformed the data to achieve normality, or used Mann–Whitney U tests where a normal distribution could not be achieved by data transformation. For the statistical analysis of sounds we used R (Version 3.3.1, We assumed a difference between sound properties to be significant if the P-value of the respective test was < 0.05.
