Interest in second language (L2) speech comprehensibility, or listeners’ perceived ease or difficulty of understanding a given utterance, has seen continual growth since Munro and Derwing's (1995) seminal publication in Language Learning. While recognizing the body of knowledge that has developed in the 25 plus years since Munro and Derwing's study, in the present paper we look to the future as we consider what an active and informative research agenda might look like for the next 10–15 years. In this regard, we propose four primary areas of future research, including a need to: (1) extend inquiry beyond a primary focus on L2 English speech, (2) explore comprehensibility more thoroughly as a social construct, (3) investigate the effects of more targeted task manipulations, and (4) delve deeper into the effects of comprehensibility-oriented instruction. We additionally discuss the need for more replication in L2 comprehensibility research while also promoting several scholarly disciplines we feel can greatly inform future research, such as task-based literature.

第二语言语音可理解性：研究议程

自 Munro 和 Derwing（1995）在语言学习。在认识到自 Munro 和 Derwing 的研究以来 25 多年中发展起来的知识体系的同时，在本文中，我们展望未来，考虑未来 10-15 年积极且内容丰富的研究议程可能会是什么样子。在这方面，我们提出了未来研究的四个主要领域，包括需要：（1）将探究扩展到第二语言英语语音的主要关注点之外，（2）更彻底地探索可理解性作为一种社会结构，（3）调查其影响更有针对性的任务操作，以及（4）更深入地研究以可理解性为导向的教学的效果。我们还讨论了在第二语言可理解性研究中进行更多复制的必要性，同时还推广了一些我们认为可以为未来研究提供极大信息的学术学科，例如基于任务的文献。
