This article discusses research into the role of audio-visual input for second language (L2) or foreign language learning. It also addresses questions related to the effectiveness of audio-visual input with different types of on-screen text such as subtitles (i.e., in learners’ first language) and captions (i.e., subtitles in the same language as the L2 audio) for L2 learning. The review discusses the following themes: (a) the characteristics of audio-visual input such as the multimodal nature of the input and vocabulary demands of video; (b) L2 learners’ comprehension of audio-visual input and the role of different types of on-screen text; (c) the effectiveness of audio-visual input and on-screen text for aspects of L2 learning including vocabulary, grammar, and listening; and (d) research into L2 learners’ use and perceptions of audio-visual input and on-screen text. The review ends with a consideration of implications for teaching practice and a conclusion that discusses the generalizability of current research in relation to suggestions for future research.

本文讨论了关于视听输入在第二语言 (L2) 或外语学习中的作用的研究。它还解决了与使用不同类型屏幕文本的视听输入有效性相关的问题，例如 L2 的字幕（即学习者的第一语言）和字幕（即与 L2 音频相同的语言的字幕）学习。审查讨论了以下主题： (a) 视听输入的特征，例如输入的多模态性质和视频的词汇需求；(b) L2 学习者对视听输入的理解以及不同类型的屏幕文本的作用；(c) 视听输入和屏幕文本对二语学习方面的有效性，包括词汇、语法和听力；(d) 研究二语学习者对视听输入和屏幕文本的使用和感知。审查结束时考虑了对教学实践的影响，并得出结论，讨论当前研究与未来研究建议相关的普遍性。
