This dataset is collected from the University of Tartu Phonetic Corpus of Estonian Spontaneous Speech. The dataset consists of words with CVCV and CVCCV structure and it has been collected for studying Estonian Quantity. The data set was collected for the paper: Lippus, P., Asu, E. L., Teras, P., & Tuisk, T. (2013). Quantity-related variation of duration, pitch and vowel quality in spontaneous Estonian. Journal of Phonetics, 41(1), 17–28. https://doi.org/10.1016/j.wocn.2012.09.005 The data set has 1714 rows and the 43 columns contain the following info: SP - Speaker ID Gender - speaker's gender, levels F (female) / M (male) Style - monologue/dialogue Word - the word (in standard orthography) Struct - word structure, levels cvcv (opened first syllable) /cvccv (closed first syllable) Quantity - Quantity degree as a number, levels 1/2/3 Quantity2 - Quantity + Structure, levels Q1 / Q2vok / Q2kons / Q3vok / Q3kons Intonation - H*L / deaccented Focus - 1 = focal stress / 0 non-focal C1 - duration of word initial consonant (ms) V1 - duration of first (stressed) syllable vowel (ms) C2 - duration of S1 coda consonant (ms) C3 - duration of second syllable onset consonant (ms) V2 - duration of second (unstressed) syllable vowel (ms) S1.dur - duration of first syllable (ms) S2.dur - duration of second syllable (ms) S1rhyme.dur - duration of first syllable rhyme (ms) Word.dur - duration of the whole word (ms) f0.v1.beg - f0 at V1 beginning (Hz) f0.v1.end - f0 at V1 end (Hz) f0.c2.end - f0 at the end of S1 coda consonant (Hz) f0.v2.beg - f0 at V2 beginning (Hz) f0.v2.end - f0 at V2 end (Hz) TP.f0 - f0 at the f0 turning point (Hz) TP.time - time of the f0 turning point from the beginning of V1 (ms) S1.f0.end - f0 at the end of the first syllable (Hz) S1.f0range - f0 range in the first syllables (in semitones) S2.f0range - f0 range in the second syllables (in semitones) TP.prop - TP proportsionaalne asukoht esimeses silbis V1.phon - the SAMPA transcription of the first vowel V2.phon - the SAMPA transcription of the second vowel V1.phon1 - first vowel phoneme (SAMPA) without length and extra symbols V3.phon1 - second vowel phoneme (SAMPA) without length and extra symbols V1F1 - first formant of the first vowel (Hz) V1F2 - second formant of the first vowel (Hz) V1F3 - third formant of the first vowel (Hz) V1F4 - fourth formant of the first vowel (Hz) V2F1 - first formant of the second vowel (Hz) V2F2 - second formant of the second vowel (Hz) V2F3 - third formant of the second vowel (Hz) V2F4 - fourth formant of the second vowel (Hz) Euk1 - Euclidian distance of the first vowel formants from the center point of the speaker's vowel space (measured in Bark) Euk2 - Euclidian distance of the second vowel formants from the center point of the speaker's vowel space (measured in Bark)
