Building on Robinson’s (2001, 2003) Cognition Hypothesis, Skehan’s (1998) Limited Attentional Capacity Model, and Kellog’s (1986) model of writing, this study examined the effect of task planning on the fluency, accuracy, and complexity of 60 Iranian EFL learners’ argumentative and narrative writings under different planning conditions. A quasi-experimental design with three levels of planning ...

Abstract This study explored the effect of speaking task on midclause pausing characteristics in L1 and L2 speech same speakers to gain further insights into potential relationship between pause location stages production. Participants included English learners French ( n = 29) or Spanish 27) from publicly available, longitudinal LANGSNAP corpus. completed two oral tasks their L2: a picture-bas...

Research studies on second language (L2) morphosyntactic variation that include multiple learner course or experience levels often conduct separate statistical analyses of the factors affecting variation, one per level, and compare significant constraints their coefficients across these groups as an indication L2 development. This method comparing regression can lead to perception differences p...

Normalized frequency data of X-JToBI prosodic labels were used to automatically discriminate 4 speech registers –academic presentation, simulated public speaking, dialogue, and reproduction speech– of the Corpus of Spontaneous Japanese (CSJ). It turned out that the use of prosodic label frequency information and speaking rate could achieve more than 85% accuracy (closed data). It also turned ou...

SmartKom is a multi-modal dialogue system which combines speech with gesture and facial expression. In this paper, we want to deal with one of those phenomena which can be observed in such elaborated systems that we want to call ‘offtalk’, i.e., speech that is not directed to the system (speaking to oneself, speaking aside). We report the classification results of first experiments which use a ...

This study describes how young Spanish-speaking children become gradually more adept at encoding temporality using grammar and discourse skills in intra-conversational narratives. The research involved parallel case studies of two Spanish-speaking children followed longitudinally from ages two to three. Type/token frequencies of verb tense, temporal/aspectual markers and narrative components we...

VideoCLEF 2009 offered three tasks related to enriching video content for improved multimedia access in a multilingual environment. For each task, video data (Dutch-language television, predominantly documentaries) accompanied by speech recognition transcripts were provided. The Subject Classification Task involved automatic tagging of videos with subject theme labels. The best performance was ...

Learning and improving natural turn-taking behaviors for dialogue systems is a topic of growing importance. In task-oriented dialogue where the user can engage in task actions in parallel with dialogue, unrestricted turn taking may be particularly important for dialogue success. This paper presents a novel Markov Decision Process (MDP) representation of dialogue with unrestricted turn taking an...
