Profile 8. reveals the outcome towards basic and second formant from the prevent of your own vowel before /?/ and in the high quality Polish and you may the newest alternatives.
As much as brand new regularity of F1 of one’s before vowel can be involved, the outcome suggest a lowered F1 on the the newest variation out of compared to the Practical Polish involved voice (NV 594 Hz against. SP 665 Hz, t=?dos.730, p : t=?dos.204, p
The outcomes including showed that the fresh new F3 frequency of the following the vowel are somewhat higher regarding the brand new alternatives when compared with the product quality Polish versions. SP dos,831 Hz, t=2.763, p : NV dos,939 Hz versus. SP dos,810 Hz, t=dos.567, p . 325, p is notably more from the Practical Shine and you will the alternatives; F1 regularity assortment was reduced in the brand new version (/?/: NV ?87 Hz versus. SP ?33 Hz, t=?dos.086, p : NV ?121 Hz vs. ?67 Hz, t=?dos.086, p=.055 (within amount of statistical inclination)). Zero significant difference between them alternatives was located into the F2 and you can F3 frequency directory of the latest before vowel. Furthermore, the fresh F1, F2 and you can F3 frequency selections of following vowel were not rather additional inside Important Shine and the the newest variant.
No high variations had been based in the duration of frication from the fricative while the affricate: if you’re Simple Shine /?/ enjoys the typical time of 0.098 s, the typical value of brand new variation was 0.101 s. bride ethiopian The new fricative an element of the affricate is actually 0.061 s when you look at the Standard Gloss and you may 0.058 s regarding the the brand new version.
Throughout new analyses demonstrated above the influence out of Speech Layout and you will Worry is significant simply in a number of models. The outcomes out of speech layout was uniform to some degree that have the research from Maniwa ainsi que al. (2009), and therefore indicated that English fricatives display other acoustic features from inside the an effective conversational against. a very clear build. REPETITION is actually more often tall, albeit only, during the formants and cycle, and frequently into the affricates than in fricatives; see the results of the newest mathematical analyses during the Appendix C.
3.step 1. Linear discriminant research
The analysis demonstrated over factors to high differences in several parameters between your the new and you can Standard Gloss sibilant. The reason for next linear discriminant research (LDA) they to exhibit hence of one’s examined variables could be the really helpful in discriminating the newest variation from the Standard Gloss variant and you will just what percentage of the information will likely be precisely classified because of the with this specific analytical method. We utilized the LDA that have jacknifed (we.elizabeth., leave you to aside) predictions. Brand new LDA had previously been efficiently used in the new discrimination regarding English fricatives (Jongman mais aussi al. 2000; McMurray and you may Jongman 2011). According to the analysis presented above, we are going to keep fricatives and you can affricates in separate teams.
In the example of the newest dictate off REPETITION try significantly other about Important Gloss and you can this new variant (t = ?dos
Most of the acoustic details displayed for the (4) was incorporated once the predictors from the LDA whatever the facts you to a number of them weren’t significant in the linear regression models. Brand new LDA outputs just one form you to greatest discriminates one another versions away from fricatives (Simple Gloss compared to. the newest variant). As the spectral top and you will COG firmly correlated together (0.79), the previous was also omitted from the model. Altogether, 19 predictors fitted the brand new LDA, 9 where didn’t significantly join new discrimination from the standard Polish in the place of the new variation. And that, the remainder details (10) were suitable towards the finally model. Brand new model are very significant (Wilks’ Lambda = 0.5251, ?2 = , df = ten, p in place of their related the latest variations.
