Contour 8. suggests the outcomes on earliest and you can second formant within avoid of your vowel before /?/ and in the product quality Polish and you may the brand new variations.
In terms of new regularity regarding F1 of your own preceding vowel can be involved, the outcomes indicate less F1 regarding the new version out-of compared to its Fundamental Polish corresponding voice (NV 594 Hz compared to. SP 665 Hz, t=?dos.730, p : t=?dos.204, p
The results as well as indicated that the latest F3 volume of one’s after the vowel is notably higher regarding the brand new variations when compared with the product quality Polish variations. SP 2,831 Hz, t=dos.763, p : NV dos,939 Hz against. SP 2,810 Hz, t=dos.567, p . 325, p is somewhat various other throughout the Fundamental Polish and new variants; F1 frequency variety try reduced in the brand new variant (/?/: NV ?87 Hz vs. SP ?33 Hz, t=?dos.086, p : NV ?121 Hz versus. ?67 Hz, t=?dos.086, p=.055 (within number of statistical interest)). No factor between the two alternatives is actually receive for the F2 and you can F3 regularity set of brand new preceding vowel. Similarly, the newest F1, F2 and you will F3 volume selections of your own following vowel were not significantly additional when you look at the Important Shine as well as the the fresh new variation.
Zero extreme distinctions have been based in the duration of frication off the fricative therefore the affricate: while you are Simple Gloss /?/ has actually the typical time of 0.098 s, the average property value this new variation is actually 0.101 s. Brand new fricative the main affricate is 0.061 s in the Practical Gloss and 0.058 s about brand new variation.
Throughout the brand new analyses displayed above the dictate off Address Layout and you may Stress are significant merely in certain designs my explanation. The results of address style was consistent somewhat which have the study regarding Maniwa ainsi que al. (2009), and therefore revealed that English fricatives display some other acoustic characteristics into the a beneficial conversational vs. an obvious style. REPETITION is actually with greater regularity high, albeit solely, for the formants and you will period, and more apparently for the affricates compared to fricatives; see the outcome of the analytical analyses inside Appendix C.
step three.step 1. Linear discriminant research
The research presented significantly more than what to significant variations in several details between the the fresh and Standard Shine sibilant. The reason for the second linear discriminant data (LDA) they to display and that of one’s investigated parameters would be the really helpful in discriminating the brand new variant on Standard Polish variant and exactly what percentage of the details might be accurately categorized because of the with this specific mathematical means. We utilized the LDA having jacknifed (i.elizabeth., get-off that away) predictions. The fresh LDA had previously been properly employed for the newest discrimination off English fricatives (Jongman et al. 2000; McMurray and you will Jongman 2011). In accordance with the analysis displayed a lot more than, we will remain fricatives and affricates inside the separate groups.
When it comes to this new determine regarding REPETITION is actually significantly additional throughout the Simple Gloss and you may the fresh new variant (t = ?2
The acoustic parameters showed when you look at the (4) was in fact provided because predictors on LDA whatever the fact one many of them were not significant regarding the linear regression patterns. The brand new LDA outputs just one form one finest discriminates one another variations off fricatives (Standard Shine against. the latest variant). Given that spectral top and you can COG firmly synchronised together (0.79), the previous has also been omitted regarding the model. Overall, 19 predictors suitable the latest LDA, 9 at which don’t notably contribute to the fresh discrimination from the quality Shine in the place of the fresh new version. Hence, the rest parameters (10) was suitable toward finally model. The fresh design try very high (Wilks’ Lambda = 0.5251, ?2 = , df = ten, p as opposed to their related the fresh variations.
