The newest linear discriminant studies revealed that each other spectral parameters and you can formant thinking sufficiently discriminate the product quality Polish and you may the fresh variation
The discriminant accurately classified 89
The results of your own acoustic test demonstrate that the sounds are formulated with a notably high spectral level in the diversity out of 20 Hz so you’re able to 11,one hundred thousand Hz compared to alveolo-palatal sibilants from Important Gloss. While the COG philosophy was in fact high for the the brand new variations than just due to their Fundamental Shine counterparts, the brand new versions away from each other /?/ and showed notably all the way down skewness beliefs than simply the Fundamental Polish corresponding segments. The newest spectra of Fundamental Polish /?/ and you may was best-skewed compared to the brand new spectra of the the fresh new alternatives which have been skewed left.
In terms of spectral slopes, the original hill (m1) out-of is actually notably lower in the newest version compared to Practical Gloss, we.elizabeth., to possess there is a great steeper rise for the Basic Gloss spectra as compared to the brand new variation on the volume region of 500 Hz so you can 5,100 Hz. Another spectral slope (m2) of each other sibilants shown somewhat all the way down values on the fresh variant as opposed to the Basic Gloss version, i.elizabeth., the new spectra of the the latest variation decrease steeper towards higher frequency area over 5,000 Hz versus spectra of one’s Basic Shine audio system.
Also, F1 regularity of before vowel differed regarding the newest alternatives when compared to the Fundamental Gloss alternatives, whereas F3 frequency out of both the preceding vowel (simply when it comes to /?/) while the adopting the vowel are rather high throughout the the brand new variants when compared to the Practical Polish versions. Eventually, merely F1 frequency range of the vowel [a] before the latest sibilants /?/ and you may is notably various other in the Standard Shine and you may the alternatives: F1 volume assortment is significantly reduced in the latest alternatives.
3% of the Important Gloss versus 76.3% of one’s the latest fricatives and you can 94% of your Basic Gloss against 88.3% of the the fresh affricates.
I’ve tried to deliver the rationale for the development of this new alternatives away from sibilants. The initial reasons invokes compare optimisation. I used multidimensional scaling to display your creative program regarding sibilants is honest Kinzan in South Korea marriage agency far more dispersed in terms of compare and you may like possibilities were preferred regarding world’s languages. The second explanation assumes one energy amount when you look at the high frequency regions enhances the cues regarding legendary expressive palatalisation that will be regularly connote the meaning off “youth” and you can “childishness”. Which inong teenage ladies and you may young women and you will gets a personality ong teenage females and you can young women given that peer-mainly based social challenges will be most effective certainly members of these ages teams. It remains to be viewed whether it linguistic feature will establish the role since an excellent marker out of a shine “feminine highlight” later. The 3rd reasons relates the alteration so you’re able to a speech diseases. If you find yourself all the about three hypotheses are often used to explain the emergence and propagation of alter, the fresh address disorder hypothesis seems to be at least probably. Of your kept two hypotheses, the new sociolinguistic one is the absolute most possible because it seems to define as to why the change is limited so you can a specific personal class, we.e. young women.
