چکیده

This paper describes how speakers adapt their language during error resolution when interacting with the animated agent Pixie. A corpus of spontaneous human-computer interaction was collected at the Telecommunication museum in Stockholm, Sweden. Adult and children speakers were compared with respect to user behavior and strategies during error resolution. In this study, 16 adults and 16 children speakers were randomly selected from a corpus from almost 3.000 speakers. This sub-corpus was then analyzed in greater detail. Results indicate that adults and children use partly different strategies when their interactions with Pixie become problematic. Children tend to repeat the same utterance verbatim, altering certain phonetic features. Adults, on the other hand, often modify other aspects of their utterances such as lexicon and syntax. Results from the present study will be useful for constructing future spoken dialogue systems with improved error handling for adults as well as children.

Speaker Adaptation in Continuous Speech Recognition Using MLLR-Based MAP Estimation

A variety of methods are used for speaker adaptation in speech recognition. In some techniques, such as MAP estimation, only the models with available training data are updated. Hence, large amounts of training data are required in order to have significant recognition improvements. In some others, such as MLLR, where several general transformations are applied to model clusters, the results ar...
