Prosodic Entrainment in an Information-Driven Dialog System
نویسندگان
چکیده
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 induce style change more effectively than the baseline of no strategy. This can translate into both better recognition and a higher chance of task success. Shouting is found to be more amenable to modification than hyperarticulation and the effect of the former on system performance is more profound.

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 کاملImplementing Acoustic-Prosodic Entrainment in a Conversational Avatar
Entrainment, aka accommodation or alignment, is the phenomenon by which conversational partners become more similar to each other in behavior. While there has been much work on some behaviors there has been little on entrainment in speech and even less on how Spoken Dialogue Systems which entrain to their users’ speech can be created. We present an architecture and algorithm for implementing ac...
