Figure 8. shows the results with the basic and you may 2nd formant from the stop of your own vowel before /?/ along with the product quality Shine and the newest variations.
In terms of the fresh volume regarding F1 of the preceding vowel can be involved, the outcomes indicate a lowered F1 throughout the the fresh new variant from than in their Standard Polish associated sound (NV 594 Hz compared to. SP 665 Hz, t=?dos.730, p : t=?dos.204, p
The outcomes and additionally showed that the fresh F3 regularity of your following the vowel was somewhat large regarding the the brand new variants when compared with the product quality Polish variations. SP 2,831 Hz, t=dos.763, p : NV 2,939 Hz against. SP 2,810 Hz, t=2.567, p . 325, p was notably other in the Basic Shine and the newest variants; F1 frequency diversity try low in the fresh version (/?/: NV ?87 Hz against. SP ?33 Hz, t=?dos.086, p : NV ?121 Hz compared to. ?67 Hz, t=?2.086, p=.055 (during the quantity of analytical inclination)). No significant difference between the two variants are discover into the F2 and F3 frequency selection of brand new before vowel. Furthermore, the fresh new F1, F2 and F3 volume ranges of the after the vowel were not significantly more into the Important Shine additionally the the latest version.
No high differences was indeed found in the duration of frication regarding the fricative plus the affricate: if you find yourself Basic Shine /?/ possess the typical time of 0.098 s, the common value of the new variation try 0.101 s. The fresh new fricative area of the affricate are 0.061 s within the Important Gloss and you will 0.058 s in the the fresh new variant.
In all brand new analyses presented over the influence from Message Concept and you will Fret are extreme simply in a few designs. The results regarding address design is consistent to some degree having the https://www.datingmentor.org/nl/geek2geek-overzicht study from Maniwa mais aussi al. (2009), which revealed that English fricatives showcase different acoustic features in a conversational versus. an obvious design. REPETITION is with greater regularity tall, albeit only, when you look at the formants and you can years, and a lot more frequently during the affricates compared to fricatives; see the results of the fresh mathematical analyses when you look at the Appendix C.
step 3.step 1. Linear discriminant analysis
The research displayed above what to high variations in numerous variables involving the the fresh and you can Simple Polish sibilant. The reason for the following linear discriminant investigation (LDA) they showing and this of your investigated parameters could be the very useful in discriminating the new variant about Basic Polish version and you will just what portion of the information might be precisely categorized of the with this particular mathematical approach. I utilized the LDA that have jacknifed (we.elizabeth., hop out you to aside) forecasts. This new LDA used to be effectively useful for this new discrimination off English fricatives (Jongman ainsi que al. 2000; McMurray and you will Jongman 2011). In accordance with the analysis presented a lot more than, we will continue fricatives and you can affricates for the separate groups.
In the example of the fresh new influence off REPETITION was significantly more from the Fundamental Gloss and the fresh new variation (t = ?2
The acoustic details presented within the (4) was basically integrated because predictors on LDA long lasting fact you to a few of them just weren’t tall about linear regression designs. Brand new LDA outputs a single means you to definitely greatest discriminates each other variations out of fricatives (Basic Polish vs. the newest version). Because the spectral peak and you will COG highly coordinated together (0.79), the former has also been omitted about design. Overall, 19 predictors fitting the LDA, nine of which did not somewhat subscribe the fresh new discrimination out-of the product quality Shine in place of the fresh new version. And that, the remaining details (10) had been installing on the last model. The fresh new design are very tall (Wilks’ Lambda = 0.5251, ?2 = , df = 10, p in place of their corresponding the newest variants.
