The recent literature on language intervention has become increasingly focused upon developing treatments that more closely parallel normal language acquisition. However, there have been relatively few reports that directly compare imitative procedures to conversational-interactive interventions. The purpose of the present study was to compare the relative effectiveness of imitative interventio...

In this paper we describe a design approach for an Artificial Conversational Companion according to earlier identified requirements of utility, adaptivity, conversational capabilities and long-term interaction. The Companion is aimed to help advanced learners of a foreign language to practice conversation via instant messenger dialogues. In order to model a meaningful long-term interaction with...

This paper describes two systems using embodied conversational agents (ECAs) for language learning. The first system, called Ville, is a virtual language teacher for vocabulary and pronunciation training. The second system, a dialogue system called DEAL, is a role-playing game for practicing conversational skills. Whereas DEAL acts as a conversational partner with the objective of creating and ...

Conversational agents integrate computational linguistics techniques with the communication channel of the Web to interpret and respond to statements made by users in ordinary natural language. Web-based conversational agents deliver high-volumes of interactive text-based dialogs. Recent years have seen significant activity in enterprise-class conversational agents. This chapter describes the p...

This report compared production of infinitival object complements during conversational language sampling to production on an elicitation task. Subjects included 25 children between the ages of 3;7 and 5;4. The children produced more two-noun infinitives and produced infinitives with more main verbs on the elicitation task. In the conversational samples, the children produced infinitives almost...

In this paper, we propose Tutoring bot, a generative chatbot trained on large scale of tutor-student conversations for English-language learning. To mimic human tutor's behavior in language education, the tutor bot leverages diverse educational instructions and grounds to each instruction as additional input context response generation. As single generally involves multiple dialogue turns give ...

PURPOSE The present study examined the nature of concurrent and predictive associations between conversational language use and reading development during early school-age years. METHOD Language and reading data from 380 twins in the Western Reserve Reading Project were examined via phenotypic correlations and multilevel modeling on exploratory latent factors. RESULTS In the concurrent pred...

The present study attempts to uncover language teachers’ beliefs about oral corrective feedback. It also explores the role of teachers’ experiences in their choice of error correction techniques. To achieve the purpose of the study, 137 foreign language teachers were asked to fill out the developed questionnaire and follow-up interviewed were conducted with 10 teachers, five novice and experien...
