The paper studies the impact of intrinsic vowel duration on category perception in boundary conditions by examining the short vs. long category boundary perception in Estonian. Since the intrinsic duration of a close vowel /i/ is about 10-15 ms shorter than that of an open vowel /a/, we hypothesize that the short vs. long category boundary in /i/ occurs at(More)
A new database project has been launched in Estonia last year. It aims the collection of telephone speech from a large number of speakers for speech and speaker recognition purposes. Up to 2000 speakers are expected to participate in recordings. SpeechDat databases, especially Finnish SpeechDat, have been chosen as a prototype for the Estonian database. It(More)
The paper studies the production and perception of Estonian quantity oppositions by native Estonians (L1 subjects) and non-native speakers with Russian-language background (L2 subjects). Estonian quantity system involves three contrastive prosodic patterns referred to as short (Q1), long (Q2) and overlong (Q3) quantity degrees. These phonological contrasts(More)
The aim of the paper is to report on the perception of Estonian vowel categories by L2 learners of Estonian whose L1 is Russian. The Estonian vowel system includes nine vowels whereas Russian has six. Five of the Estonian vowels have counterparts in Russian: /i/, /e/, /u/, /o/ and /a/, the new vowel categories for L2 speakers are /ü/, /ö/, /ä/, and partly(More)
A seismic reflection, gravity, and aeromagnetic reconnaissance was made in the Pensacola Mountains, Antarctica, during the 1965-66 austral summer. Prominent ice streams located between the Neptune and Patuxent Ranges and east of the Forrestal Range overlie channels in the rock surface 2000 meters below sea level which are probably of glacial origin. Seismic(More)
This paper deals with the perceptual assessment of Russian-accented Estonian. Speech samples were recorded from 20 speakers with a Russian background; clips of about 20 seconds from each speaker were selected for this perceptual study. The accentedness was rated in two tests: first, 20 native Estonian speakers judged the samples and rated the degree of(More)
