← Language & CommunicationWhy does speech recognition software struggle when users simultaneously speak and perform iconic gestures?
A)Segmentation errors cause prosodic shift
B)Lexical access overrides sensorimotor integration
C)Phonetic content competes with gesture iconicity✓
D)Acoustic models disregard visual prosody
💡 Explanation
Speech recognition models primarily process auditory input; therefore, the presence of iconic gestures creates competition for cognitive resources during phonetic analysis. Because gesture iconicity introduces a visual-motor representation of meaning, rather than purely phonetic information, it can interfere with acoustic processing.
