Item Automatic English phoneme recognition from articulatory data generated by EPG systems with grid and anatomical layout of contact sensors(Australasian Speech Science and Technology Association Inc., 2019-08-22) Krynicki, Grzegorz; Dziubalska-Kołaczyk, Katarzyna; Weckwerth, Jarosław; Michalski, Grzegorz; Kaźmierski, Kamil; Maciejewska, Barbara; Wiskirska-Woźnica, Bożena; Żygis, Marzena; Kuczko, Wiesław; Sekuła, AlicjaThe aim of the study was to conduct automatic phoneme identification from articulatory data that accompanied the production of these phonemes in continuous speech. The articulatory data were obtained from 2 electropalatographic systems, Palatometer by Complete Speech and Linguagraph by Rose-Medical. Palatometer was used with the artificial palate containing 124 contact sensors in a grid layout, including 2 sensors monitoring the lip contact. The palate included a vacuum-thermoformed flexible printed circuit. Linguagraph was used with the acrylic artificial palate designed and developed for the purpose of this study, containing 62 electrodes in anatomical layout. Palatometer was used by one native of General American and Linguagraph by one native of General British, each reading 140 phonetically balanced sentences that included Harvard Sentences and TIMIT prompts. The EPG data were parametrised into dimensionality reduction indexes, which were analysed by means of linear discriminant analysis and a probabilistic neural network. The results of classifications are discussed.Item Durational variation in Polish fricatives provides evidence for hybrid models of phonology(Australasian Speech Science and Technology Association, 2019-08-22) Kaźmierski, KamilThe neighborhood density of a word is the number of words that sound similar to it. Phonotactic probability is a measure of how typical (for a given language) the phoneme sequences in a word are. These two factors are known to affect speech perception in opposing directions: high neighborhood density slows down processing while high phonotactic probability speeds it up [30]. This finding supports hybrid models of phonological representation [24], as neighborhood density effects operate on lexical, and phonotactic probability effects on sublexical representations. The present paper, investigating word-initial double clusters retrieved from the Greater Poland Spoken Corpus [14], tests the predictions for durational variation in fricatives following from Vitevitch and Luce [30]. It has been found that high neighborhood density is associated with longer - while high phonotactic probability with shorter - fricative durations. Thus, further support for hybrid models of phonological storage is provided.Item The relationship between gender identity and six f0 measures in Polish(University of Glasgow, 2015) Kaźmierski, KamilThis paper reports on a study of the relationship between gender identity, as measured by the Bem Sex-Role Inventory (BSRI) and six characteristics of F0 (mean, median, minimum, maximum, range and standard deviation) in semi-spontaneous speech of 24 Polish female speakers. Despite ample evidence suggesting that gender identity exerts an influence on voice quality, notably on pitch, whose main acoustic correlate is F0, the statistical analysis of the data gathered for the present study does not attest to a relationship between the BSRI score and F0 measures. An elaboration of culture-specific tool for measuring gender identity, as well as supplementing acoustic measurements with physiological and articulatory data are suggested as methodological developments needed to verify whether there are links between gender identity and F0 in Polish.
