We model human responses to speech recognition errors from a corpus of human clarification strategies. We employ learning techniques to study 1) the decision to either stop and ask a clarification question or to continue the dialogue without clarification, and 2) the decision to ask a targeted clarification question or a more generic question. Targeted clarification questions focus specifically...

In this paper, the effects of prosodic features on the interpretation of elliptical clarification requests in dialogue are studied. An experiment is presented where subjects were asked to listen to short human-computer dialogue fragments in Swedish, where a synthetic voice was making an elliptical clarification after a user turn. The prosodic features of the synthetic voice were systematically ...

The ability to request clarification of utterances is a vital part of the communicative process. In this paper we discuss the range of possible forms for clarification requests, together with the range of readings they can convey. We present the results of corpus analysis which show a correlation between certain forms and possible readings, together with some indication of maximum likely distan...

The aim of the present study is to explore the form and function of clarification request sequences in interaction involving children with cochlear implants. Clarification request sequences are investigated in everyday interaction, and it is demonstrated that children with CI use both general/open and specific requests for clarification. It is also shown that there is relatively lower frequency...

This paper presents a digital filtering algorithm which clarifies dysphonic speech with the speaker’s individuality preserved. The study deals with the clarification of oesophageal speech and the speech of patients with cerebral palsy, and the filtering ability is being evaluated by listening experiments. Over 20,000 patients are currently suffered from laryngeal cancer in Japan, and the only t...
