Cohesion, Entrainment and Task Success in Educational Dialog
نویسنده
چکیده
Researchers often study dialog corpora to better understand what makes some dialogs more successful than others. In this talk I will examine the relationship between coherence/entrainment and task success, in several types of educational dialog corpora: 1) one-on-one tutoring, where students use dialog to interact with a human tutor in the physics domain, 2) one-on-one tutoring, where students instead interact with a spoken dialog system, and 3) engineering design, where student teams engage in multi-party dialog to complete a group project. I will first introduce several corpus-based measures of both lexical and acousticprosodic dialog cohesion and entrainment, and extend them to handle multi-party conversations. I will then show that the amount of cohesion and/or entrainment positively correlates with measures of educational task success in all of our corpora. Finally, I will discuss how we are using our findings to build better tutorial dialog systems.

Prosodic Entrainment and Tutoring Dialogue Success
This study investigates the relationships between student entrainment to a tutoring dialogue system and learning. By finding the features of prosodic entrainment which correlate with learning, we hope to inform educational dialogue systems aiming to leverage entrainment. We propose a novel method to measure prosodic entrainment and find specific features which correlate with user learning. We a...
متن کاملProsodic Entrainment in an Information-Driven Dialog System
This paper explores entrainment of two speaking styles, shouting and hyperarticulation, in an information-driven spoken dialog system. Both styles present difficulties for automatic speech recognition. We describe and evaluate the system’s detection and reaction mechanisms for these speaking styles, which involve deploying appropriate dialog-level strategies. The three strategies tested do indu...
متن کاملEntrainment in Speech Preceding Backchannels
In conversation, when speech is followed by a backchannel, evidence of continued engagement by one’s dialogue partner, that speech displays a combination of cues that appear to signal to one’s interlocutor that a backchannel is appropriate. We term these cues backchannel-preceding cues (BPC)s, and examine the Columbia Games Corpus for evidence of entrainment on such cues. Entrainment, the pheno...
متن کاملSpeaking More Like You: Lexical, Acoustic/Prosodic, and Discourse Entrainment in Spoken Dialogue Systems
When people engage in conversation, they adapt the way they speak to the speaking style of their conversational partner in a variety of ways. For example, they may adopt a certain way of describing something based upon the way their conversational partner describes it, or adapt their pitch range or speaking rate to a conversational partner’s. They may even align their turn-taking style or use o...
متن کاملLexical entrainment of real users in the let's go spoken dialog system
This paper examines the lexical entrainment of real users in the Let’s Go spoken dialog system. First it presents a study of the presence of entrainment in a year of human-transcribed dialogs, by using a linear regression model, and concludes that users adapt their vocabulary to the system’s. This is followed by a study of the effect of changing the system vocabulary on the distribution of word...
