Summary
This summary is machine-generated.

Computer-assisted presentations (CAP) result in a distinct speech rhythm characterized by faster articulation and more regular, elongated pauses. This prosodic style, observed in most subjects, can disrupt communication when speech closely follows slide changes.

Area of Science:

  • Linguistics
  • Speech Science
  • Communication Studies

Context:

  • Computer-assisted presentations (CAP) often exhibit unique speech patterns compared to spontaneous speech.
  • These patterns may include altered rhythm, melody, and pauses.
  • Understanding these prosodic features is crucial for effective communication.

Purpose:

  • To analyze the prosody and temporal organization of speech in inexperienced subjects during CAP.
  • To compare the speech characteristics of CAP with presentations without visual aids (PWS).
  • To identify the typical prosodic style associated with CAP.

Summary:

  • Analysis of 37 subjects revealed a distinct prosodic style in three-quarters of participants during CAP.
  • This style featured a faster articulatory rate and more regular, elongated pauses, particularly during slide transitions.
  • Speech signal analysis and perceptual experiments confirmed these findings, linking them to the temporal organization of prominences.

Impact:

  • The study validates the assumption of a characteristic prosodic rhythm in CAP.
  • Subjects exhibiting this typical CAP prosody often synchronized their speech too closely with slide changes, hindering communication.
  • Findings offer insights into optimizing speech delivery in visual-supported presentations to improve audience engagement.
