Contour 8. shows the outcomes towards the basic and you will 2nd formant on stop of the vowel before /?/ plus the product quality Gloss and you can the fresh new variations.
So far as the volume out of F1 of one’s before vowel is concerned, the results point out a lower F1 on the the fresh new version of compared to their Basic Shine involved sound (NV 594 Hz versus. SP 665 Hz, t=?dos.730, p : t=?dos.204, p
The results along with showed that the brand new F3 regularity of your pursuing the vowel is rather higher on the the newest versions when compared to the high quality Gloss variations. SP dos,831 Hz, t=2.763, p : NV dos,939 Hz compared to. SP dos,810 Hz, t=2.567, p . 325, p are somewhat some other throughout the Standard Shine and you may this new variations; F1 frequency range was reduced in the brand new variation (/?/: NV ?87 Hz compared to. SP ?33 Hz, t=?dos.086, p : NV ?121 Hz versus. ?67 Hz, t=?2.086, p=.055 (within amount of mathematical inclination)). Zero factor between them variants is actually discover on the F2 and you will F3 volume range of new before vowel. Likewise, the brand new F1, F2 and you can F3 frequency range of your own following vowel just weren’t somewhat other when you look at the Basic Gloss plus the brand new variation.
No significant variations was found in the time of frication of both the fricative and affricate: when you find yourself Fundamental Gloss /?/ has an average duration of 0.098 s, the average value of this new variation is actually 0.101 s. The fricative part of the affricate is actually 0.061 s in the Standard Shine and 0.058 s about new variation.
In every brand new analyses exhibited above the dictate off Speech Layout and you will Fret are high simply in a number of models. The results off address style was uniform to some degree with the analysis out of Maniwa et al. (2009), hence indicated that English fricatives exhibit some other acoustic qualities in a conversational compared to. a very clear style. REPETITION was with greater regularity tall, albeit solely, within the formants and you may stage, and a lot more apparently from inside the affricates than in fricatives; see the results of the fresh analytical analyses in Appendix C.
step three.1. Linear discriminant data
The analysis exhibited a lot more than items to high variations in several variables within the fresh new and you can Standard Polish sibilant. The purpose of the next linear discriminant investigation (LDA) they showing which of your own investigated variables may be the very helpful in discriminating the latest variation regarding the Simple Polish variant and you may exactly what portion of the information and knowledge shall be precisely classified from the using this type of analytical method. I made use of the LDA that have jacknifed (i.elizabeth latin woman date date., log off you to aside) predictions. The newest LDA used to be efficiently useful for the fresh discrimination away from English fricatives (Jongman et al. 2000; McMurray and you may Jongman 2011). According to the analysis shown a lot more than, we’ll remain fricatives and you can affricates for the independent groups.
In the example of the latest dictate out-of REPETITION is notably other throughout the Standard Polish and you will the new version (t = ?dos
The acoustic parameters showed during the (4) were provided due to the fact predictors on the LDA regardless of the facts you to definitely a number of them just weren’t high about linear regression habits. The brand new LDA outputs just one setting one to better discriminates one another versions away from fricatives (Basic Shine compared to. the latest variation). As the spectral peak and you can COG strongly correlated along (0.79), the previous was also omitted from the model. As a whole, 19 predictors suitable the newest LDA, 9 where don’t significantly subscribe to brand new discrimination out-of the high quality Gloss in place of brand new variant. And that, the remaining variables (10) were installing to your last model. The newest design is actually highly extreme (Wilks’ Lambda = 0.5251, ?2 = , df = ten, p in the place of their involved the latest variants.
