Figure 8. reveals the results into the earliest and you can second formant in the avoid of your own vowel preceding /?/ plus in the standard Polish and you can the latest variants.
As far as the new frequency from F1 of the preceding vowel is worried, the outcomes point out a diminished F1 in the the variant regarding compared to the Simple Gloss corresponding sound (NV 594 Hz compared to. SP 665 Hz, t=?2.730, p : t=?2.204, p
The results plus showed that the fresh F3 regularity of following vowel try significantly higher from the the variations in comparison to the high quality Polish alternatives. SP dos,831 Hz, t=2.763, p : NV 2,939 Hz vs. SP 2,810 Hz, t=dos.567, p . 325, p try significantly additional on the Important Shine and you will brand new versions; F1 frequency variety was reduced in the fresh version (/?/: NV ?87 Hz compared to. SP ?33 Hz, t=?2.086, p : NV ?121 Hz versus. ?67 Hz, t=?dos.086, p=.055 (from the number of statistical interest)). No significant difference among them variations is receive to your F2 and you can F3 frequency directory of the newest preceding vowel. Similarly, the fresh F1, F2 and F3 regularity selections of the after the vowel were not significantly other for the Fundamental Shine as well as the brand new version.
Zero significant variations was basically found in the lifetime of frication out of both fricative as well as the affricate: while you are Fundamental Gloss /?/ features the average lifetime of 0.098 s, the typical worth of the latest variant is 0.101 s. New fricative area of the affricate try 0.061 s from inside the Fundamental Gloss and you can 0.058 s on the brand new version.
In every the analyses exhibited over the dictate regarding Message Build and you will Fret is actually high merely in a few patterns. The outcome from address concept is consistent to some extent that have the analysis off Maniwa et al. (2009), hence revealed that English fricatives display more acoustic properties from inside the an effective conversational against. a very clear layout. REPETITION is more often extreme, albeit entirely, for the formants and stage, plus apparently in affricates than in fricatives; understand the results of Toyota brides the fresh new statistical analyses for the Appendix C.
step 3.1. Linear discriminant analysis
The research presented a lot more than things to extreme variations in multiple parameters between your the fresh and you will Simple Gloss sibilant. The goal of next linear discriminant studies (LDA) they showing and therefore of the examined details will be the very helpful in discerning the variant throughout the Important Gloss variation and what part of the details are going to be precisely categorized because of the with this mathematical means. We used the LDA which have jacknifed (we.elizabeth., get-off one out) predictions. The fresh new LDA was once properly useful for new discrimination away from English fricatives (Jongman et al. 2000; McMurray and Jongman 2011). According to the research exhibited a lot more than, we shall continue fricatives and you may affricates during the separate groups.
In the case of the fresh influence away from REPETITION is rather other regarding Practical Shine and you may the brand new variant (t = ?dos
All of the acoustic details exhibited inside (4) have been included once the predictors in the LDA whatever the facts you to definitely a number of them weren’t significant on linear regression habits. New LDA outputs a single form that finest discriminates each other alternatives out of fricatives (Simple Polish compared to. the newest version). Since spectral peak and COG highly coordinated collectively (0.79), the former was also excluded about design. In total, 19 predictors fitting the newest LDA, nine from which don’t rather donate to the discrimination away from the high quality Gloss in place of the newest version. And that, the rest parameters (10) was in fact installing toward latest design. This new design is actually highly extreme (Wilks’ Lambda = 0.5251, ?2 = , df = 10, p as opposed to their involved the new alternatives.
