Relationship between speaker/listener similarity and information transmission quality in speech communication

We investigate the correlation between similarity in speaker characteristics and information transmission quality using a map task dialogue corpus. Similarity between the prosodic features and lexical styles of different speakers are analyzed, and most of these similarity measurements are shown to have significant correlations with information transmission quality as measured by a direction following task. We also combine these similarity measurements using a linear regression prediction model and assess information transmission quality. Prediction scores show a significant 0.37 correlation coefficient between the combined similarity measurement and information transmission quality scores.
