Contour 8. shows the outcome on the earliest and you may second formant from the avoid of your vowel before /?/ and in the standard Polish and you will the variants.
So far as the newest frequency from F1 of the before vowel can be involved, the outcomes indicate a lesser F1 about the version of than in the Important Shine relevant voice (NV 594 Hz compared to. SP 665 Hz, t=?2.730, p : t=?2.204, p
The outcome plus indicated that the brand new F3 frequency of your own adopting the vowel was notably higher throughout the brand new versions when compared to the quality Gloss variants. SP dos,831 Hz, t=2.763, p : NV dos,939 Hz versus. SP dos,810 Hz, t=2.567, p . 325, p is significantly more from the Standard Polish and you may the fresh alternatives; F1 volume range is lower in the variant (/?/: NV ?87 Hz compared to. SP ?33 Hz, t=?2.086, p : NV ?121 Hz compared to. ?67 Hz, t=?dos.086, p=.055 (from the level of analytical tendency)). Zero significant difference between the two variations try discover into F2 and you can F3 regularity selection of the new preceding vowel. Similarly, the newest F1, F2 and you will F3 regularity selections of following the vowel just weren’t somewhat other in Standard Gloss together with the variation.
Zero tall distinctions were found in the lifetime of frication away from both the fricative in addition to affricate: whenever you are Basic Polish /?/ provides the common lifetime of 0.098 s, the average worth of the newest variation is 0.101 s. The fresh fricative part of the affricate are 0.061 s during the Fundamental Shine and you can 0.058 s regarding the the fresh new variant.
Throughout the latest analyses exhibited over the determine out-of Speech Concept and you can Worry was significant simply in a number of activities. The results off message concept try uniform somewhat that have the analysis of Maniwa ainsi que al. (2009), hence showed that English fricatives exhibit various other acoustic features from inside the an effective conversational vs. a clear layout. REPETITION are more often high, albeit solely, within the formants and you may period, and seem to in the affricates than in fricatives; comprehend the results of the brand new statistical analyses for the Appendix C.
The research exhibited a lot more than items to tall variations in numerous details amongst the the new and you can Standard Shine sibilant. The reason for the following linear discriminant study (LDA) it to exhibit and therefore of one’s examined variables would be the extremely helpful in discerning the brand new version throughout the Simple Gloss version and exactly what percentage of the information will be accurately categorized because of the with this mathematical method. We used the LDA which have jacknifed (we.age., hop out one aside) predictions. New LDA was once efficiently useful brand new discrimination out-of English fricatives (Jongman ainsi que al. 2000; McMurray and you can Jongman 2011). According to research by the research displayed over, we are going to remain fricatives and affricates inside independent groups.
The acoustic variables demonstrated within the (4) was indeed provided because the predictors in the LDA whatever the fact you to definitely a number of them were not high in the linear regression designs. This new LDA outputs one setting you to definitely finest discriminates both alternatives from fricatives (Standard Gloss against. the newest variant). Given that spectral peak and you may COG highly coordinated along (0.79), the previous was also omitted regarding the design. Overall, 19 predictors fitting brand new LDA, 9 at which failed to notably contribute to the latest discrimination from the standard Gloss versus the new version. And therefore, the remaining variables (10) have been installing toward finally design. The fresh new model are extremely significant (Wilks’ Lambda = 0.5251, ?2 = , df = ten, p as opposed to its associated the variants.
