A system for adaptive high-variability segmental perceptual training: implementation, effectiveness, transfer
Language Learning & Technology 22(1), 69-96, DOI:10125/44582

This paper introduces the first version of Linguatorium Auris, a system for segmental perceptual training that utilizes corpus-based word frequency lists, high variability phonetic input, and text-to-speech technology to automatically create discrimination and identification perception exercises customized for individual learners. The effectiveness of this system is evaluated in an experiment with a pre-/post-test design involving 32 adult Russian-speaking learners of English as a foreign language (EFL).

The effectiveness of computer-based spaced repetition in foreign language vocabulary instruction: A double-blind study
CALICO Journal, 33(3), 334-354, DOI: 10.1558/cj.v33i3.26055

The purpose of this paper is twofold: First, we present an empirical study evaluating the effectiveness of Linguatorium Lexis. The study demonstrated that by spending an average of three minutes each day on automatically generated vocabulary activities, students increased their long-term vocabulary retention rate threefold. Second, we demonstrate that the double-blind experiment design, which is the standard in such high-stakes fields as healthcare, has potential for research in computer-assisted language learning.

This paper won CALICO Journal's award for best article of the year.

Speech synthesis technologies in teaching English vocabulary
Izvestija SPbGUEF, 2013(2), 75-79

This article is a short paper published in a Russian-language peer-reviewed journal. In the article, we describe two small-scale experiments that point towards the value of text-to-speech (TTS) in generating vocabulary-learning activities. TTS voice quality was found to have no significant effect on learning gains, although students strongly preferred high-quality voices.
