Optimizing Automated Call Routing by Integrating Spoken Dialog Models with Queuing Models

چکیده

Organizations are increasingly turning to spoken dialog systems for automated call routing to reduce call center costs. To maintain quality service even in cases of failure, these systems often resort to ad-hoc rules for dispatching calls to a human operator. We present a principled procedure for determining when callers should be transferred to operators based on a cost-benefit analysis. The procedure integrates models that predict when a call is likely to fail using spoken dialog features with queuing models of call center volume and service time. We evaluate how the procedure would have performed on cases drawn from logs of interactions with a legacy spoken dialog system.

How may I help you?

We are interested in providing automated services via natural spoken dialog systems. By natural, we mean that the machine understands and acts upon what people actually say, in contrast to what one would like them to say. There are many issues that arise when such systems are targeted for large populations of non-expert users. In this paper, we focus on the task of automatically routing telepho...

A Spoken Language System for Automated Call Routing 3. Language Modeling

1. ABSTRACT We are interested in the problem of understanding u-ently spoken language. In particular, we consider people's responses to the open-ended prompt of 'How May I help you?'. We then further restrict the problem to classifying and automatically routing such a call, based on the meaning of the user's response. Thus, we aim at extracting a relatively small number of semantic actions from...

Automated wizard-of-oz for spoken dialogue systems

Designing and building natural language spoken dialogue systems require large amounts of speech utterances, which adequately represent the intended human-machine dialogues. For this purpose, typically, first a “Wizard-of-Oz” data collection is performed, and then the collected data is transcribed and labeled by expert labelers. Finally, the data is used to train both the speech recognizer and t...

Stochastic language models for speech recognition and understanding

Stochastic language models for speech recognition have traditionally been designed and evaluated in order to optimize word accuracy. In this work, we present a novel framework for training stochastic language models by optimizing two different criteria appropriate for speech recognition and language understanding. First, the language entropy and salience measure are used for learning the releva...

One Year of Contender: What Have We Learned about Assessing and Tuning Industrial Spoken Dialog Systems?

A lot. Since inception of Contender, a machine learning method tailored for computerassisted decision making in industrial spoken dialog systems, it was rolled out in over 200 instances throughout our applications processing nearly 40 million calls. The net effect of this data-driven method is a significantly increased system performance gaining about 100,000 additional automated calls every mo...
