Error Resolution Strategies for Interactive Television Speech Interfaces

چکیده
Using speech input to augment the remote control can be an alternative interaction technique for interactive television. However, little is known about how to design such a system that is suitable for the home environment. In this paper we explore possible error resolution strategies in the case of speech recognition errors in a TV-setting. From previous research two techniques have been identified: repetition of input by the user and choice of interpretation. From these two techniques, four alternative strategies, suitable for a TV-environment, were designed and tested with a Wizard-of-Oz method: one with repetition and three based on choosing the best alternative from an n-list given in audio and visual mode, alone or combined. The results show that displaying an n-best list gives the most efficient interaction. Redundant audio feedback does not influence the performance.

New Forms of Interacting with the Television in an Ambient Environment
In the past there has been a lot of research in the area of humancomputer interaction. With the arrival of digital television, the television becomes more and more like a computer. A new form of television is being introduced: interactive television. The only interaction with the television in the past was via the remote control. Interactive television provides opportunities for new interaction...
متن کاملInteractive Error Resolution Strategies for Speech-to-Speech Translation Systems
1 In this demonstration, we will showcase BBN’s Speech-to-Speech (S2S) translation system that employs novel interaction strategies to resolve errors through user-friendly dialog with the speaker. The system performs a series of analysis on input utterances to detect out-ofvocabulary (OOV) named-entities and terms, sense ambiguities, homophones, idioms and ill-formed inputs. This analysis is us...
متن کاملPredicting hyperarticulate speech during human-computer error resolution
When speaking to interactive systems, people sometimes hyperarticulate— or adopt a clarified form of speech that has been associated with increased recognition errors. The goals of the present study were: (1) to establish a flexible simulation method for studying users’ reactions to system errors, (2) to analyze the type and magnitude of linguistic adaptations in speech during human-computer er...
