Figure 8. suggests the results towards the earliest and you will second formant on stop of vowel preceding /?/ and also in the quality Shine and you may the brand new versions.
In terms of the newest volume of F1 of preceding vowel is concerned, the outcome suggest a lower life expectancy F1 regarding the the fresh new variant off compared to the Important Polish associated sound (NV 594 Hz vs. SP 665 Hz, t=?dos.730, p : t=?2.204, p
The outcomes together with revealed that the newest F3 volume of one’s after the vowel was significantly higher throughout the this new variations when compared to the high quality Gloss variations. SP dos,831 Hz, t=dos.763, p : NV 2,939 Hz vs. SP 2,810 Hz, t=dos.567, p . 325, p was somewhat additional throughout the Fundamental Gloss and you may the latest variants; F1 regularity variety is actually reduced in brand new version (/?/: NV ?87 Hz versus. SP ?33 Hz, t=?dos.086, p : NV ?121 Hz vs. ?67 Hz, t=?2.086, p=.055 (at quantity of statistical interest)). No significant difference between the two versions was receive to your F2 and you may F3 frequency range of the brand new before vowel. Likewise, this new F1, F2 and you may F3 volume range of one’s adopting the vowel just weren’t somewhat more during the Important Gloss therefore the the new variation.
No tall differences was based in the lifetime of frication from both fricative plus the affricate: if you’re Standard Polish /?/ possess an average lifetime of 0.098 s, the common property value brand new version is actually 0.101 s. The fricative area of the affricate try 0.061 s during the Basic Gloss and 0.058 s on the new variant.
In all the newest analyses exhibited above the determine off Address Build and you will Stress try extreme simply in a few models. The outcome out of speech build are consistent somewhat that have the analysis out of Maniwa mais aussi al. (2009), and that revealed that English fricatives display additional acoustic characteristics in the a beneficial conversational versus. a very clear layout. REPETITION was more frequently significant, albeit only, when you look at the formants and you can cycle, plus frequently when you look at the affricates compared to fricatives; understand the outcome of the fresh statistical analyses for the Appendix C.
step three.1. Linear discriminant investigation
The research shown above what to extreme variations in numerous variables between the the fresh and you will Basic Gloss sibilant. The goal of the next linear discriminant data (LDA) they to demonstrate and that of your own examined parameters is the most helpful in discriminating brand new variation about Practical Shine variation and just what part of the data is going to be truthfully classified by the with this particular analytical method. We made use of the LDA having jacknifed (i.elizabeth., log off one to out) predictions. The brand new LDA used to be efficiently employed for the new discrimination regarding English fricatives (Jongman et al. 2000; McMurray and you will Jongman 2011). In line with the research exhibited over, we are going to remain fricatives and you can affricates for the independent communities.
When it comes to the new determine out of REPETITION are significantly various other on Standard Polish and you can the fresh new variant (t = ?2
All acoustic parameters demonstrated into the (4) was included while the predictors regarding the LDA long lasting truth one to some of them were not high on the linear regression habits. The LDA outputs just one setting one top discriminates one another variations out of fricatives (Simple Shine vs. the fresh variant). Because the spectral height and you can COG highly correlated with each other (0.79), the former was also excluded in the design. Altogether, 19 predictors fitting the fresh new LDA, 9 of which failed to rather sign up for the latest discrimination out-of the standard Polish instead of the latest variation. And that, the rest variables (10) were fitted towards finally model. The fresh design is actually highly tall (Wilks’ Lambda = 0.5251, ?2 = , df = 10, pop over to these guys p versus their involved new versions.
