Variation in Prosodic Signature with Cognitive Load

Abstract
Multiple studies have explored various facets of speech, such as voice quality, prosody, articulation, accent, and rhythm in different contexts. Research has demonstrated that speech spontaneity is influenced by both cognitive and physical abilities. Most of these studies have evaluated speech features at an aggregate level across different individuals to draw general inferences. However, examining how speech variation occurs within the same individual across different situations is a promising area that warrants detailed research.

Prosody-intonation, stress, and rhythm pattern a speaker exhibits while conveying a message- plays a vital role in communication.Itprovidesinsightsintothespeaker'ssurroundings,stress levels, emotions, intentions, and, to some extent, truthfulness. In our study, we investigated how people’s responses vary when speaking about basic life truths (such as reading a paragraph about a well-known fact) versus when they answer questions that require cognitive effort to think, recall, analyze, and phrase their responses. We observed that cognitive effort increases in situations involving confusion, stress, and anxiety, leading to dramatic variations in prosodic signatures from their truth baseline.
