How do the elderly talk to a natural language call routing system?

چکیده
This paper investigates spontaneous utterances in response to a telecom IVR prompting the caller with “Please tell me in a few words what your inquiry is about”. In responses from a typical caller base (n=29830, age-mixed) the median utterance length was 3 words. A qualitative analysis (n=74) of senior speakers (age 70+) and adult speakers (age 50 and below) revealed that seniors were significantly more verbose (median of 11 and 3 words per utterance, respectively). The seniors generally expressed themselves more formally than those below 50. Our findings suggest that some seniors confuse the IVR with a telephone answering machine.

Discriminative training in natural language call routing
In this paper, we show how discriminative training can be used to improve classifiers used in natural language processing, using as an example the task of natural language call routing. In natural language call routing, callers are routed to desired departments based on natural spoken responses to an open-ended “How may I direct your call?” prompt. With vector-based natural language call routin...
متن کاملRe-imagining Research: A Bold Call, but Bold Enough?; Comment on “Experience of Health Leadership in Partnering with University-Based Researchers in Canada: A Call to ‘Re-Imagine’ Research”
Many articles over the last two decades have enumerated barriers to and facilitators for evidence use in health systems. Bowen et al’s article “Response to Experience of Health Leadership in Partnering with University-Based Researchers: A Call to ‘Re-imagine Research’” furthers the debate by focusing on an under-explored research area (health system design and health service organization) with ...

The development and evolution of any system–person, organization–nation depends on how the system succeeds to bridge the gap between what the system knows and what the system does (with the knowledge). We call this the gap between knowing and doing or the knowing-doing gap. If the system does not do what it knows, it will lose out in competition with other systems, its relative performance in...
متن کاملIntegrated Natural Language Call Routing
We present a new integrated approach for natural language call routing based on stochastic language models. The system learns automatically from examples to direct a call to the appropriate destination within a call center. It employs stochastic language models for each call destination. The language models are generated by a language model adaptation algorithm based on the minimum discriminati...
متن کاملTeaching approaches to Computer Assisted Language Learning
Computers have been used for language teaching ever since the 1960's.Learning a second language is a challenging endeavor, and, for decades now, proponents of computer assisted language learning (CALL) have declared that help is on the horison. We investigate the suitability of deploying speech technology in computer based systems that can be used to teach foreign language skills. In this case,...
