Profile 8. shows the outcome into the first and second formant in the avoid of vowel before /?/ plus the high quality Polish and you may the latest variations.

So far as this new volume out of F1 of your own preceding vowel is worried, the outcomes suggest a reduced F1 about new variant off compared to its Fundamental Shine involved sound (NV 594 Hz compared to. SP 665 Hz, t=?dos.730, p : t=?2.204, p

The results as well as revealed that brand new F3 volume of adopting the vowel is somewhat large throughout the the new variants in comparison to the standard Gloss versions. SP dos,831 Hz, t=2.763, p : NV dos,939 Hz compared to. SP dos,810 Hz, t=dos.567, p . 325, p is actually rather various other from the Standard Polish and you can this new alternatives; F1 frequency diversity try low in new variation (/?/: NV ?87 Hz versus. SP ?33 Hz, t=?2.086, p : NV ?121 Hz against. ?67 Hz, t=?dos.086, p=.055 (on amount of mathematical desire)). Zero factor between the two variants was located towards F2 and F3 frequency a number of this new preceding vowel. Also, the brand new F1, F2 and you may F3 frequency selections of adopting the vowel just weren’t significantly other from inside the Fundamental Shine in addition to the variant.

No extreme differences were based in the time of frication out of both fricative additionally the affricate: if you are Basic Shine /?/ enjoys the average time of 0.098 s, the common worth of the newest variant was 0.101 s. The new fricative an element of the affricate are 0.061 s when you look at the Simple Shine and you may 0.058 s regarding the the variation.

In most the brand new analyses showed above the determine away from Address Style and Stress is high simply in certain habits. The results from address design is actually consistent somewhat with the analysis out of Maniwa ainsi que al. (2009), which indicated that English fricatives exhibit other acoustic features in good conversational versus. a very clear design. REPETITION was more frequently tall, albeit only, when you look at the formants and you can duration, and much more frequently when you look at the affricates than in fricatives; comprehend the result of the fresh new mathematical analyses when you look at the Appendix C.

step three.step one. Linear discriminant data

The research exhibited more than things to tall variations in multiple variables amongst the new and you will Simple Gloss sibilant. The reason for next linear discriminant investigation (LDA) it to demonstrate which of one’s examined parameters are the very helpful in discriminating the fresh variant regarding the Standard Polish variant and what portion of the details is accurately classified by using this type of mathematical strategy. We made use of the LDA which have jacknifed (i.e., hop out you to definitely out) forecasts. The new LDA was previously effectively useful for the brand new discrimination out of English fricatives (Jongman ainsi que al. 2000; McMurray and Jongman 2011). In accordance with the research shown more than, we’re going to keep fricatives and you will affricates during the separate groups.

Regarding brand new influence off REPETITION are rather various other on Standard Shine and you will the newest variation (t = ?dos

All of the acoustic parameters displayed in (4) was indeed integrated because predictors on LDA whatever the truth you to a lot of them weren’t tall on the linear regression patterns. The new LDA outputs a single setting you to definitely top discriminates one another variants away from fricatives (Important Shine against. the latest version). While the spectral top and you will COG firmly coordinated along (0.79), the previous was also omitted regarding the design. Altogether, 19 predictors suitable the LDA, nine of which didn’t somewhat contribute to this new discrimination of the product quality Polish versus the fresh version. Hence, the rest variables (10) was indeed fitting to the finally model. The model are highly high (Wilks’ Lambda = 0.5251, ?2 = , df = 10, p as opposed to the related this new alternatives.
