Abstract

ABSTRACT: Purpose: This study aimed to map studies that investigated the influence of speech rate on the reproduction of audiovisual resources in university students' learning using a Scope review.

Research strategies: The PCC strategy was used where P- University students, C- Increased or decreased speech rate, C- Learning. The searches were conducted using the SciELO, Lilacs, PubMed, Scopus, Web of Science, and Google Scholar databases.

Selection criteria: Scientific articles published in the databases above with a target audience of university students were included; works that compared average speech rate with increased or decreased speed and had learning-related skills as the study response.

Data analysis: The Joanna Briggs Institute checklists were used for methodological quality assessment.

Results: We found that four articles observed an improvement in learning performance when the audiovisual resource was presented at a speed of up to 2x, three did not observe a difference and two studies observed a worsening in the skills involved in learning.The results indicate a low risk of bias in most studies included.

Conclusion: A study indicated improved learning in audiovisuals at a speed slower than 1x. It was observed that reproduction speed rates of audiovisual resources impact university students' learning process. Rates greater than 2x limit the learning process. Rates within the normal range (between 1x and 1.75x) are more favorable for capturing the content.
