The newest linear discriminant study indicated that both spectral details and formant viewpoints sufficiently discriminate the standard Polish and you will the fresh new variation
The newest discriminant correctly classified 89
The results of acoustic test demonstrate that the fresh music are manufactured that have a somewhat high spectral top regarding the assortment out of 20 Hz to help you 11,100 Hz as compared to alveolo-palatal sibilants regarding Fundamental Shine. Because the COG thinking was large on the the newest variations than for their Basic Gloss counterparts, the brand new versions regarding both /?/ and you will showed somewhat down skewness values than the Fundamental Gloss corresponding locations. The latest spectra of the Basic Shine /?/ and you will have been proper-skewed compared with the latest spectra of the brand new variants hence were skewed to the left.
For spectral slopes, the first slope (m1) regarding try significantly low in the variation compared to Fundamental Gloss, i.elizabeth., to have there is an excellent steeper go up toward Fundamental Polish spectra compared to the brand new version towards frequency region regarding five hundred Hz in order to 5,100 Hz. The second spectral mountain (m2) off each other sibilants shown somewhat down opinions on the latest variant as opposed to the Practical Polish variant, i.age., brand new spectra of your new variation decrease steeper for the high regularity area above 5,100 Hz than the spectra of the Fundamental Gloss audio system.
Additionally, F1 frequency of your own preceding vowel differed regarding new alternatives when compared to the Fundamental Polish alternatives, whereas F3 regularity from both before vowel (just regarding /?/) together with following the vowel is notably higher on the latest versions when compared to the Simple Shine versions. Ultimately, merely F1 regularity selection of the latest vowel [a] preceding the latest sibilants /?/ and you may try somewhat additional regarding the Standard Gloss and you will brand new variants: F1 regularity variety is significantly low in the newest variations.
3% of your Important Shine against 76.3% of brand new fricatives and you can 94% of the Standard Gloss against 88.3% of the the fresh new affricates.
We have made an effort to provide the rationale toward development of the versions out-of sibilants. The initial reasons invokes compare optimisation. We utilized multidimensional scaling to demonstrate that the innovative program out-of sibilants is more spread regarding examine and you can instance possibilities were prominent on earth’s dialects. Another reasons assumes one to times quantity inside the higher regularity places enhances the signs regarding renowned expressive palatalisation that’s accustomed connote the meaning away from “youth” and you will “childishness”. This inong teenage women and you will young women and will get an identification ong adolescent women and you will women while the fellow-created public demands will be the strongest one of members of these many years organizations. They remains to be viewed if or not it linguistic attribute will determine the character because a good marker out-of a gloss “feminine accent” afterwards. The third factor relates the change so you can a speech infection. If you’re every about three hypotheses are often used to explain the development and you will propagation of alter, the latest address diseases theory is apparently at least most likely. Of your remaining a few hypotheses, the brand new sociolinguistic a person is many possible as it is able to identify as to why the alteration is bound to a certain social group, i.e. young women.
