Profile 8. suggests the outcomes into the very first and you may 2nd formant from the prevent of the vowel preceding /?/ plus the quality Polish and you will this new variations.
In terms of new regularity off F1 of before vowel can be involved, the outcomes suggest a lower F1 regarding the latest variation out of compared to the Fundamental Gloss involved voice (NV 594 Hz versus. SP 665 Hz, t=?2.730, p : t=?dos.204, p
The outcomes along with revealed that the newest F3 volume of your own following vowel is actually somewhat high on the the new variants when compared with the standard Gloss variants. SP dos,831 Hz, t=2.763, p : NV dos,939 Hz vs. SP 2,810 Hz, t=2.567, p . 325, p was rather various other regarding Practical Gloss and the fresh variations; F1 volume range is lower in the newest variation (/?/: NV ?87 Hz against. SP ?33 Hz, t=?2.086, p : NV ?121 Hz compared to. ?67 Hz, t=?2.086, p=.055 (from the level of analytical inclination)). Zero factor between the two variants is actually found on the F2 and you can F3 regularity range of the latest preceding vowel. Furthermore, the new F1, F2 and you can F3 volume selections of one’s pursuing the vowel dating ladies Latina were not somewhat some other inside the Practical Polish plus the the fresh variant.
No extreme variations were found in the duration of frication out-of both the fricative together with affricate: while you are Standard Polish /?/ provides an average lifetime of 0.098 s, the typical property value the latest variation are 0.101 s. The fricative area of the affricate was 0.061 s in the Important Polish and 0.058 s from the the newest variation.
Throughout the new analyses presented above the influence off Speech Style and you may Be concerned is actually extreme simply in a few habits. The outcomes of speech style are uniform somewhat which have the research from Maniwa mais aussi al. (2009), hence indicated that English fricatives display more acoustic services for the an effective conversational versus. a definite layout. REPETITION try with greater regularity extreme, albeit only, inside formants and you will course, and much more apparently when you look at the affricates compared to fricatives; see the consequence of the brand new analytical analyses into the Appendix C.
step 3.step one. Linear discriminant studies
The research demonstrated more than things to significant variations in numerous details amongst the the brand new and you may Basic Shine sibilant. The reason for the next linear discriminant research (LDA) they to exhibit and therefore of the examined details will be the very helpful in discriminating the newest variation regarding the Fundamental Gloss version and you will what portion of the information and knowledge is going to be truthfully classified by using this analytical approach. I utilized the LDA having jacknifed (i.elizabeth., hop out that away) forecasts. The fresh new LDA used to be effortlessly used in the latest discrimination out of English fricatives (Jongman ainsi que al. 2000; McMurray and you may Jongman 2011). In line with the studies exhibited a lot more than, we are going to keep fricatives and affricates during the separate groups.
In the example of the latest influence out-of REPETITION was somewhat various other throughout the Fundamental Gloss and you may new version (t = ?dos
Every acoustic parameters displayed inside the (4) was incorporated since predictors on the LDA whatever the facts you to many weren’t tall on linear regression habits. The new LDA outputs an individual form one to best discriminates one another variations of fricatives (Basic Shine against. new variation). Because spectral level and COG strongly correlated with each other (0.79), the former was also excluded on the model. Altogether, 19 predictors suitable the fresh new LDA, 9 of which didn’t significantly subscribe to the brand new discrimination of the standard Polish instead of the new version. Which, the rest variables (10) were installing towards finally model. New model is actually extremely significant (Wilks’ Lambda = 0.5251, ?2 = , df = 10, p in place of their involved the latest variants.
