The fresh new discriminant correctly categorized 89

The results of your own acoustic try out demonstrate that new audio are made that have a considerably high spectral peak throughout the range off 20 Hz to eleven,100 Hz as compared to alveolo-palatal sibilants out-of Practical Shine. Since COG beliefs have been highest towards the brand new variants than just for their Standard Shine competitors, the fresh versions out of each other /?/ and you may exhibited significantly straight down skewness philosophy than simply their Fundamental Gloss corresponding areas. The fresh spectra of the Standard Polish /?/ and you may was in fact best-skewed compared to the latest spectra of your own the new versions hence was in fact skewed left.

In terms of spectral mountains, the initial hill (m1) away from was somewhat low in the version than in Fundamental Polish, i.elizabeth., for you will find a beneficial steeper increase on Important Shine spectra compared to the the fresh variation to your volume part off 500 Hz in order to 5,one hundred thousand Hz. The second spectral mountain (m2) of each other sibilants presented rather straight down values in the the latest variation when compared to the Standard Gloss variation, we.age., the fresh spectra of your own new variant dropped steeper to the high volume region more than 5,100000 Hz as compared to spectra of your own Simple Polish speakers.

In addition, F1 regularity of one’s preceding vowel differed regarding the latest alternatives when compared to the Standard Shine variants, whereas F3 frequency regarding both preceding vowel (merely when it comes to /?/) as well as the adopting the vowel was significantly highest on the fresh variants in comparison to the Simple Gloss variants. In the end, just F1 regularity variety of the latest vowel [a] before the fresh new sibilants /?/ and try significantly different regarding the Simple Polish and the new alternatives: F1 frequency range try notably low in the brand new variations.

3% of your Practical Gloss vs 76.3% of one’s the latest fricatives and 94% of the Important Gloss versus 88.3% of your the latest affricates.

We have tried to deliver the rationale for the development of the brand new variations from sibilants. The initial factor invokes examine optimization. I used multidimensional scaling to exhibit that creative program of sibilants is far more spread with regards to contrast and such as for example systems include popular in the earth’s languages. The next reasons assumes you to definitely time attention inside the highest volume regions raises the signs of legendary expressive palatalisation which will be used to connote the definition away from “youth” and “childishness”. So it inong teenage female and you can ladies and you can becomes an identification ong adolescent ladies and you will young women as the fellow-depending public challenges are definitely the strongest certainly one of members of this type of ages teams. It is still around seen whether or not that it linguistic characteristic will establish their character since the an excellent marker from a gloss “women accent” subsequently. The 3rd reasons applies the alteration in order to a demonstration illness. When you are every three hypotheses can be used to explain the introduction and you can propagation of your own alter, the brand new speech problems hypothesis appears to be the least probably. Of one’s kept a couple of hypotheses, this new sociolinguistic a person is more plausible because it manages to explain why the alteration is limited so you can a specific personal classification, i.age. young women.
