Paralinguistic Cues

Aspects of spoken communication that carry meaning beyond the literal words themselves: tone of voice, pitch contour, loudness, rhythm, tempo, stress, pauses, and voice quality. Paralinguistic cues convey emotion, emphasis, sarcasm, uncertainty, speaker identity, and social relationship, and hearing audiences absorb them automatically alongside the linguistic content. Traditional captions strip most paralanguage out, reducing speech to a flat transcript. This is a widely reported pain point for d/DHH viewers and motivates research on expressive captions, affective captions, and haptic augmentations that restore paralinguistic information through typography, colour, position, animation, or vibration.
