Influence of speech rate and information density on recognition: the moderate dynamic mechanism

Abstract

This article analyzes whether recognition in the news may be affected by speech rate and information density and addresses what the optimal level would need to be for information on the radio to be encoded and recognized as effectively as possible. The key question is whether the combination of these two factors has a decisive influence on cognitive processing, especially in the distribution of resources allocated and required to encode the message. The findings indicate that Speech Rate does have a decisive influence on recognition of information since it modifies the resources available for encoding the message. The higher the speed, the lower the information density should be and vice versa. The best result to achieve the greatest recognition is between 170 (high density) and 190 (low density) words per minute, confirming that a moderate dynamic mechanism takes place.
