Shape 8. reveals the results into first and you will next formant in the end of one’s vowel preceding /?/ plus in the high quality Gloss and you will this new versions.
So far as brand new volume from F1 of preceding vowel can be involved, the outcome point out a lesser F1 on new variant off than in the Standard Gloss involved sound (NV 594 Hz compared to. SP 665 Hz, t=?dos.730, p : t=?dos.204, p
The results in addition to indicated that the new F3 frequency of following the vowel is actually somewhat large on the fresh alternatives when compared with the high quality Gloss variations. SP 2,831 Hz, t=2.763, p : NV dos,939 Hz versus. SP dos,810 Hz, t=dos.567, p . 325, p is notably additional on the Fundamental Polish and the brand new variations; F1 frequency range are reduced in the brand new version (/?/: NV ?87 Hz versus. SP ?33 Hz, t=?dos.086, p : NV ?121 Hz vs. ?67 Hz, t=?dos.086, p=.055 (during the amount of mathematical inclination)). No significant difference between the two variants is discovered into F2 and you may F3 regularity list of brand new before vowel. Similarly, brand new F1, F2 and you may F3 volume ranges of your following vowel were not rather additional for the Practical Polish in addition to the latest version.
Zero high variations were based in the duration of frication regarding the fricative plus the affricate: if you are Practical Gloss /?/ enjoys the typical lifetime of 0.098 s, the common property value this new variant is 0.101 s. The fresh fricative an element of the affricate was 0.061 s inside the Important Polish and 0.058 s in the new my explanation variation.
Throughout the newest analyses shown above the influence away from Address Build and Stress is extreme simply in a number of designs. The results out-of message style was uniform somewhat having the research from Maniwa et al. (2009), and that indicated that English fricatives display some other acoustic characteristics in a beneficial conversational vs. a definite layout. REPETITION is more often tall, albeit exclusively, inside formants and you will years, and more seem to during the affricates than in fricatives; understand the outcome of new statistical analyses within the Appendix C.
3.1. Linear discriminant data
The study demonstrated significantly more than factors to significant differences in numerous parameters involving the the fresh new and you may Basic Polish sibilant. The goal of next linear discriminant data (LDA) it to show and this of the examined details will be really useful in discerning the new version throughout the Fundamental Polish variation and you can just what portion of the information might be correctly classified from the with this statistical method. We made use of the LDA which have jacknifed (we.elizabeth., get off that aside) forecasts. The latest LDA was previously effectively used in the discrimination of English fricatives (Jongman ainsi que al. 2000; McMurray and you can Jongman 2011). According to the analysis shown over, we will remain fricatives and you can affricates inside separate communities.
When it comes to this new influence regarding REPETITION is rather some other on the Practical Gloss and you will the latest variant (t = ?2
All of the acoustic parameters shown for the (4) have been incorporated because the predictors throughout the LDA long lasting truth one to many just weren’t high regarding the linear regression habits. The fresh LDA outputs an individual means one to greatest discriminates each other variations regarding fricatives (Fundamental Shine versus. the version). Since spectral level and you may COG strongly synchronised together (0.79), the previous has also been excluded throughout the model. Altogether, 19 predictors fitted brand new LDA, nine where did not notably sign up for the latest discrimination from the quality Shine in place of the version. And that, the rest variables (10) were suitable to your final model. The brand new model was extremely tall (Wilks’ Lambda = 0.5251, ?2 = , df = ten, p in place of its corresponding new alternatives.
