We measure face deformations during speech production using a motion capture system, which provides 3D coordinate data of about 60 markers glued on the speaker's face. An arbitrary orthogonal factor analysis followed by a principal component analysis (together called a guided PCA) of the data has showed that the first 6 factors explain about 90% of the variance, for each of our 3 speakers. The 6 derived factors, therefore, allow us to efficiently analyze or to reconstruct with a reasonable accuracy the observed face deformations. Since these factors can be interpreted in articulatory terms, they can reveal underlying articulatory organizations. The comparison of lip gestures in terms of data derived factors suggests that these speakers differently maneuver the lips to achieve contrast between /s/ and /R/. Such inter-speaker variability can occur because the acoustic contrast of these fricatives is shaped not only by the lip tube but also by cavities inside the mouth such as the sublingual cavity. In other words, these tube and cavity can acoustically compensate each other to produce their required acoustic properties.
Bilježenje palatalnih konsonanata najviše je problema izazivalo u slavenskih naroda koji su nastojali prilagoditi osnovnu latinicu fonemima svojih jezika. U ovom se radu promatraju bilježenja palatala u pisaca zadarsko-šibenskoga kruga, i to u vremenu od 14. do 17. stoljeća. U toj su regiji nastali prvi hrvatski tekstovi pisani latinicom. Cilj rada jest ustvrditi kako su pojedini autori latinicom zapisali sporne foneme hrvatskoga (čakavskoga) jezika, koje su razlike i istosti njihovih grafijskih rješenja i koje se tendencije ogledaju u višestoljetnoj uporabi latinice na ovom području.
This study examines the movement trajectories of the dorsal tongue movements during symmetrical /VCa/ -sequences, where /V/ was one of the Hungarian long or short vowels /i,a,u/ and C either the voiceless palatal or velar stop consonants. General aims of this study were to deliver a data-driven account for (a) the evidence of the division between dorsality and coronality and (b) for the potential role coarticulatory factors could play for the relative frequency of velar palatalization processes in genetically unrelated languages. Results suggest a clear-cut demarcation between the behaviour of purely dorsal velars and the coronal palatals. Moreover, factors arising from a general movement economy might contribute to the palatalization processes mentioned.
