Figure 8. suggests the outcome towards the basic and 2nd formant during the avoid of vowel before /?/ plus in the high quality Polish and this new variations.
As far as this new volume of F1 of preceding vowel is worried, the results point to a diminished F1 from the the fresh new variant from compared to its Standard Gloss related voice (NV 594 Hz compared to. SP 665 Hz, t=?dos.730, p : t=?dos.204, p
The results also revealed that new F3 frequency of your own following the vowel try somewhat higher regarding the this new variants when compared to the high quality Shine versions. SP dos,831 Hz, t=2.763, p : NV 2,939 Hz versus. SP dos,810 Hz, t=dos.567, p . 325, p is actually notably some other throughout the Fundamental Shine and you may the newest alternatives; F1 volume range are lower in the brand new variation (/?/: NV ?87 Hz vs. SP ?33 Hz, t=?2.086, p : NV ?121 Hz versus. ?67 Hz, t=?dos.086, p=.055 (at the amount of analytical desire)). Zero significant difference between the two versions are discover into F2 and you will F3 frequency listing of the before vowel. Likewise, new F1, F2 and F3 volume range of your own adopting the vowel were not notably various other in the Fundamental Gloss in addition to the fresh new variant.
Zero extreme distinctions was in fact based in the lifetime of frication out-of both the fricative and affricate: if you are Practical Shine /?/ features the common duration of 0.098 s, the common property value this new variation are 0.101 s. New fricative part of the affricate are 0.061 s during the Fundamental Polish and 0.058 s about the fresh version.
In all the analyses showed over the determine from Speech Design and you may Stress was tall merely in a few habits. The results from message design try uniform to some degree that have the analysis away from Maniwa mais aussi al. (2009), and that indicated that English fricatives display various other acoustic services when you look at the a beneficial conversational against. a clear design. REPETITION is with greater regularity high, albeit entirely, inside formants and you may course, plus frequently inside the affricates compared to fricatives; understand the outcome of the brand new statistical analyses from inside the Appendix C.
3.1. Linear discriminant research
The study presented more than things to extreme differences in numerous variables between the the fresh new and Standard Gloss sibilant. The objective of next linear discriminant research (LDA) it showing hence of one’s examined details is the most helpful in discriminating the variation regarding the Simple Gloss variant and you can just what percentage of the data would be correctly classified by the using this statistical means. I used the LDA with jacknifed (i.e., get off you to aside) forecasts. The new LDA was once successfully employed for this new discrimination away from English fricatives (Jongman et al. 2000; McMurray and Jongman 2011). Based on the research showed above, we will remain fricatives and you will affricates from inside the independent organizations.
Regarding new determine off REPETITION are notably other on Important Gloss and you may the version (t = ?dos
Most of the acoustic parameters displayed during the (4) was provided due to the fact predictors regarding the LDA long lasting fact that a lot of them weren’t high regarding the linear regression designs. The brand new LDA outputs one form one most useful discriminates both versions away from fricatives (Practical Shine versus. brand new version). As spectral height and you will COG firmly synchronised along (0.79), the previous has also been excluded regarding the design. Overall, 19 predictors suitable the newest LDA, nine of which didn’t rather subscribe to the newest discrimination away from the quality Gloss instead of new variation. Hence, the remaining details (10) have been fitted with the http://kissbrides.com/christian-filipina-review/ latest design. The model try highly tall (Wilks’ Lambda = 0.5251, ?2 = , df = ten, p versus the associated brand new variants.
