A Distributed Architecture for Cooperative Spoken Dialogue Agents with Coherent Dialogue State and History
نویسندگان
چکیده
It has been very difficult to develop spoken dialogue systems with high domain extensibility. Not only the system complexity inevitably increases with the number of topics and domains, but the concurrent topics need to be handled persistently and consistently across different domains. This paper presents a distributed architecture for cooperative spoken dialogue agents with high domain extensibility. Under this architecture, different spoken dialogue agents handling different domains can be developed independently, and cooperate with one another to respond to the user’s requests, while a user interface agent can access the correct spoken dialogue agent through a domain switching protocol, and carry over the dialogue state and history so as to keep the knowledge processed persistently and consistently across different domains. Initial experiments provide very encouraging results.

Towards End-to-End Spoken Dialogue Systems with Turn Embeddings
Training task-oriented dialogue systems requires significant amount of manual effort and integration of many independently built components; moreover, the pipeline is prone to errorpropagation. End-to-end training has been proposed to overcome these problems by training the whole system over the utterances of both dialogue parties. In this paper we present an end-to-end spoken dialogue system a...

متن کاملThe CommandTalk Spoken Dialogue System
CommandTalk (Moore et al., 1997) is a spokenlanguage interface to the ModSAF battlefield simulator that allows simulation operators to generate and execute military exercises by creating forces and control measures, assigning missions to forces, and controlling the display (Ceranowicz, 1994). CommandTalk consists of independent, cooperating agents interacting through SRI's Open Agent Architectu...
متن کاملA Concurrent, Distributed, and Incremental Spoken Dialogue Architecture with a First Application to Prosody
Current-day spoken dialogue systems are tedious to interact with (Ward et al. 2005). eir naturalness and (measurable) quality of interaction can be improved through incremental (step-by-step) processing schemes that enable dialogue systems to interact continuously (Baumann 2013). However, incremental models have not yet adequately addressed the challenge of joint decision making and optimizatio...
