Figure 8. reveals the outcome for the earliest and you may second formant during the end of one’s vowel before /?/ along with the standard Polish and you will the fresh new variants.
As far as this new regularity regarding F1 of before vowel can be involved, the outcome point out a lesser F1 in the the fresh version of compared to the Fundamental Shine associated sound (NV 594 Hz compared to. SP 665 Hz, t=?dos.730, p : t=?dos.204, p
The outcome as well as showed that new F3 frequency of following the vowel was somewhat higher on the the latest variations in comparison to the standard Shine versions. SP 2,831 Hz, t=dos.763, p : NV 2,939 Hz compared to. SP dos,810 Hz, t=dos.567, p . 325, p was significantly various other on Practical Polish and you can this new alternatives; F1 volume diversity are reduced in new version (/?/: NV ?87 Hz compared to. SP ?33 Hz, t=?2.086, p : NV ?121 Hz vs. ?67 Hz, t=?dos.086, p=.055 (on amount of mathematical interest)). Zero significant difference between the two variants try found on F2 and you can F3 frequency range of the before vowel. Furthermore, this new F1, F2 and you will F3 frequency selections of your following vowel weren’t notably other from inside the Important Polish as well as the the newest version.
No extreme differences had been found in the time of frication out-of both the fricative and the affricate: when you are Standard Gloss /?/ has actually an average lifetime of 0.098 s, an average property value this new version try 0.101 s. This new fricative area of the affricate try 0.061 s into the Standard Gloss and you will 0.058 s regarding the the fresh new variant.
Throughout the newest analyses showed above the influence from Address Concept and you may Worry are high just in a number of models. The results out of message design was consistent somewhat with the analysis regarding Maniwa ainsi que al. (2009), and this indicated that English fricatives display other acoustic services during the an effective conversational against. a clear layout. REPETITION try more often extreme, albeit exclusively, inside formants and period, and a lot more frequently for the affricates than in fricatives; comprehend the consequence of the fresh new statistical analyses in Appendix C.
step three.step one. Linear discriminant study
The research exhibited more than points to extreme variations in multiple parameters involving the this new and you will Fundamental Polish sibilant. The intention of the next linear discriminant study (LDA) they to demonstrate and that of your own examined variables are the most helpful in discriminating new variant on the Important Shine variant and you can exactly what part of the information and knowledge shall be truthfully classified by the with this particular analytical method. We made use of the LDA which have jacknifed (i.e., get off that aside) predictions. The newest LDA had previously been efficiently used for the newest discrimination away from English fricatives (Jongman mais aussi al. 2000; McMurray and you can Jongman 2011). According to research by the research shown above, we shall keep fricatives and you can affricates from inside the independent groups.
In the case of this new influence out-of REPETITION try somewhat more from the Simple Shine and you may this new variation (t = ?dos
All the acoustic details presented inside (4) was indeed incorporated as predictors on the LDA long lasting facts you to definitely some of them were not tall on the linear regression designs. The newest LDA outputs a single mode that most useful discriminates each other variants from fricatives (Simple Polish versus. brand new variation). Because spectral top and you will COG strongly coordinated with each other (0.79), the previous was also omitted about design. Altogether, 19 predictors suitable the new LDA, nine from which did not notably subscribe the newest discrimination out of the product quality Polish in place of brand new variant. And that, the rest variables (10) was indeed fitted on the finally model. The brand new model was very significant (Wilks’ Lambda = 0.5251, ?2 = , df = ten, p rather than the involved the fresh variations.
