How seeing a speaker's face affects listening effort for native and nonnative English speakers

Listening effort and audiovisual speech by L1 ("native") and LX ("nonnative") English speakers

NIH-funded research Carleton College · NIH-10730305

This study is looking at how seeing a speaker's face affects how hard it is for people who speak English as a second language to understand what they're saying, especially when there's background noise, and it involves some college students helping out along the way.

What this research studies

This research investigates how visual cues from a speaker's face influence the effort required to understand speech, particularly for individuals who speak English as a second language. It aims to clarify whether seeing a speaker helps or hinders comprehension by measuring listening effort through various methods, including subjective assessments and recall tasks. The study will also explore how background noise impacts this effort and whether language proficiency alters the experience of listening. Undergraduate researchers will be involved throughout the process, contributing to a comprehensive understanding of these dynamics.

Who could benefit from this research

Good fit: Ideal candidates for this research include both native English speakers and those for whom English is a second language, particularly in settings where visual cues are present.

Not a fit: Patients who are not involved in language processing or who do not engage in environments requiring speech comprehension may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could enhance communication strategies for both native and nonnative English speakers, improving their ability to understand speech in various environments.

How similar studies have performed: Previous research has shown that visual input can significantly affect speech comprehension, but this study aims to provide new insights by focusing on nonnative speakers and varying listening conditions.
