Islands of failure: employing word accent information for pronunciation quality assessment of English L2 learners
نویسندگان
چکیده
So far, applied research aiming at computer-assisted pronunciation training has normally concentrated on segmental aspects. Here, we present a database with realizations of nonnative English speakers with German, French, Spanish, and Italian as native language. We concentrate on the acoustic-prosodic modelling of word accent position and use a large prosodic feature vector to automatically recognize erroneous word accent positions produced by non-native English speakers.

Computer Assisted Pronunciation Training: Target- ing Second Language Vowel Perception Improves Pronunciation
This paper first provides an overview of factors that constrain ultimate attainment in adult second language (L2) pronunciation, finding that first language influence and the quantity and quality of L2 phonetic input account for much of the variation in the degree of foreign accent found across adult L2 learners. The author then evaluates current approaches to computer assisted pronunciation tr...
متن کاملProsodic transfer in L2 relative prominence distribution: the case study of Japanese pitch accent produced by Italian learners
Relative prominence distribution, one of the major factors characterizing speech rhythm, is largely determined not only by the position of word accent/stress (word accent, henceforth) but also by the treatment of the acoustic correlates involved in word accent production (e.g., duration, F0, amplitude). Languages differ in both aspects, and those differences are expected to cause prosodic trans...

High degree of between-rater variability in pronunciation assessment is often reported in literature. However, human assessments of pronunciation skills of second language (L2) learners are used in standardized languageproficiency tests. Besides, these scores are used as a reference point in evaluating computer-based systems for pronunciation teaching and testing. Therefore it is important to b...

This work reports on the construction of a rated database of spontaneous speech produced by second language (L2) learners of English. Spontaneous speech was collected from 28 L2 speakers representing six language backgrounds and five different proficiency levels. Speech was elicited using formats similar to that of the TOEFL iBT and the SPEAK (Speaking Proficiency English Assessment Kit) test. ...
