Shape 8. shows the outcome for the first and you will second formant from the Cair girls for marriage prevent of vowel before /?/ and also in the standard Gloss and you will the new variations.
In terms of the regularity away from F1 of the preceding vowel is concerned, the results point out a reduced F1 regarding the new variation out-of than in its Fundamental Shine related sound (NV 594 Hz vs. SP 665 Hz, t=?2.730, p : t=?dos.204, p
The outcome including indicated that the new F3 volume of the following vowel are somewhat high throughout the the new alternatives when comparing to the quality Shine versions. SP dos,831 Hz, t=dos.763, p : NV dos,939 Hz against. SP 2,810 Hz, t=2.567, p . 325, p is significantly different regarding the Practical Shine and the brand new alternatives; F1 volume range are lower in the new version (/?/: NV ?87 Hz compared to. SP ?33 Hz, t=?2.086, p : NV ?121 Hz compared to. ?67 Hz, t=?2.086, p=.055 (in the level of statistical interest)). Zero significant difference between them variants try receive into the F2 and you will F3 frequency selection of the brand new before vowel. Likewise, brand new F1, F2 and F3 regularity selections of one’s following the vowel just weren’t somewhat other within the Standard Gloss and the brand new version.
No extreme distinctions were based in the lifetime of frication from both the fricative in addition to affricate: while Simple Shine /?/ enjoys the common duration of 0.098 s, an average worth of this new version try 0.101 s. This new fricative an element of the affricate was 0.061 s when you look at the Simple Polish and 0.058 s regarding the the newest version.
In every the fresh new analyses exhibited over the dictate away from Speech Concept and you will Worry are extreme simply in a few activities. The outcomes away from address build is actually uniform to some degree with the research out-of Maniwa mais aussi al. (2009), and that revealed that English fricatives exhibit different acoustic functions from inside the an effective conversational compared to. a very clear concept. REPETITION is actually with greater regularity significant, albeit solely, into the formants and you will stage, and a lot more frequently into the affricates than in fricatives; see the result of the new analytical analyses for the Appendix C.
3.1. Linear discriminant investigation
The research showed significantly more than factors to extreme differences in multiple parameters amongst the brand new and Basic Polish sibilant. The goal of the second linear discriminant research (LDA) they to demonstrate and therefore of your own examined details will be the most helpful in discerning this new variation on Important Gloss variant and what portion of the information might be correctly categorized by using this statistical strategy. We utilized the LDA with jacknifed (we.age., get off that away) predictions. The brand new LDA was previously efficiently useful the discrimination from English fricatives (Jongman ainsi que al. 2000; McMurray and you may Jongman 2011). In accordance with the study exhibited significantly more than, we’ll remain fricatives and you can affricates in the independent communities.
In the example of brand new dictate out-of REPETITION is rather additional regarding the Practical Gloss and you will new variation (t = ?2
The acoustic details showed in (4) was basically incorporated because the predictors in the LDA no matter what truth that some of them just weren’t tall from the linear regression patterns. The fresh LDA outputs just one form you to definitely better discriminates one another variations from fricatives (Basic Polish vs. the fresh new variant). Since the spectral peak and you can COG highly correlated collectively (0.79), the former has also been omitted regarding the design. Altogether, 19 predictors fitted the new LDA, 9 from which didn’t notably sign up to the brand new discrimination regarding the quality Gloss instead of the fresh new version. And that, the remaining details (10) have been fitted with the latest design. The latest design was extremely high (Wilks’ Lambda = 0.5251, ?2 = , df = ten, p in the place of its relevant the fresh new versions.
