Measurements of VOT in the production of initial stops in English and Slovenian : research data underlying the article

Stopar, Andrej (author)

Six L1 Slovenian female speakers (mean age: 25.2), all MA students of English, were recorded reading sets of isolated words in Slovenian and English. They were instructed to produce each item at a natural speaking rate, pausing between individual words. The recordings were analysed acoustically in Praat, and VOT duration values were extracted. The Slovenian set consisted of forty-eight existing words representing all six Slovenian stops (/p t k b d g/) in word initial, stressed syllable position, each combined with one of the eight Slovenian vowels (/i e ɛ ə a ɔ o u/). The list was read twice: first with items grouped by the following vowel (e.g., pita, tik, kip …), and then with items grouped by the initial stop (e.g., pita, péta, pêta …). The English set contained seventy-one items representing the corresponding English stops combined with each of the twelve British English monophthongs (/iː ɪ e ɛ: æ ɜ: ʌ ɑː ɒ ɔː u: ʊ/). These items were likewise read twice, following the same procedure as for Slovenian: first grouped by the following vowel (e.g., Peter, teak, Turk …), and then by the initial stop (e.g., Peter, pits, pets …). The uneven total number of English items (71) reflects a gap in the /d/ set: no suitable candidate beginning with /dʊ/ could be identified. VOT measurements (in ms) are listed in a CVS table, organized by word, speaker (S1, S2, S3, S4, S5 and S6) and repetition (VOT-1 and VOT-2). The file SLO_VOT_data.csv contains the Slovenian data, and the file ENG_VOT_data.csv the English data.

Abstract

Šest govork slovenščine kot prvega jezika (povprečna starost: 25,2 let) – vse so študentke magistrskega študija angleščine – je bilo posnetih pri branju nabora izoliranih besed v slovenščini in angleščini. Bralke so bile naprošene, naj berejo v naravnem govornem tempu ter naj med posameznimi besedami naredijo kratek premor. Posnetki so bili akustično analizirani v programu Praat, iz njih pa so bile izluščene vrednosti trajanja VOT v milisekundah. Slovenski nabor besed je obsegal oseminštirideset obstoječih besed, ki se začnejo na šest zapornikov (/p t k b d g/) v začetnem položaju besede in v naglašenem zlogu, sledi pa jim eden od osmih samoglasnikov (/i e ɛ ə a ɔ o u/). Nabor besed je bil prebran dvakrat: prvič tako, da so si besede sledile glede na naslednji samoglasnik (npr. pita, tik, kip …), drugič pa glede na začetni zapornik (npr. pita, péta, pêta …). Angleški nabor besed je obsegal enainsedemdeset enot, ki se začnejo na ustrezne angleške zapornike ter jim sledi eden od dvanajstih britanskih enoglasnikov (/iː ɪ e ɛ: æ ɜ: ʌ ɑː ɒ ɔː u: ʊ/). Tudi ta nabor besed je bil prebran dvakrat, po enakem postopku kot slovenski: najprej z združevanjem po samoglasniku (npr. Peter, teak, Turk …), nato pa po začetnem zaporniku (npr. Peter, pits, pets …). Skupno število angleških enot (71) odraža vrzel v naboru za /d/, saj ni primerne besede, ki bi se začela z /dʊ/. Meritve VOT (v ms) so navedene v razpredelnici po besedah, govorkah (S1, S2, S3, S4, S5, S6) in ponovitvi branja (VOT-1 ali VOT-2). Datoteka SLO_VOT_data.csv vsebuje slovenske podatke, datoteka ENG_VOT_data.csv pa angleške.
