The Need for Speed: investigating the influence of audio speed on listening comprehension
| Resumo: | With the emergence of Massive Open Online Courses (MOOCs) and the rise of online classes, more students accelerate video and audio. While it allows faster content consumption, its impact on listening comprehension remains unclear. In this study, we aim to understand how listening comprehension is affected by listening to audio at fast (1.5x) and very fast (2x) speeds, compared to its baseline speed (1x), while controlling for individual learning factors and participants’ perception of the stimuli. In each of the three sessions, 48 students listened to one audio sample, selected from a previous pilot study, at one of the three speeds. Afterwards, participants filled out an evaluation test and a perception questionnaire. In the last session, we administered a sociodemographic questionnaire and the Reading Span Test (Gaspar, 2001). Logistic mixed-effects models showed that when audio speed increases, there is a gradual decrease in performance on the evaluation tests, although it is only significant between 1x and 2x speeds. Importantly, this effect of speed persists even when accounting for individual learning factors and content perception factors. These findings bear implications for individuals who accelerate audio content, shedding light on the search for an optimal playback speed. |
