特殊语言能力 (英语为：xenoglossy，来源于希腊语词汇 ξενογλωσσία - xenoglossia, 这个词由两部分组成：ξένος - xenos， 异族的 + γλώσσα - glossa， 意思是舌头、语言)是一种难以考证的超自然现象。是指某人能流利的讲一种他自己没有从自然的方法学习到接触到的语言。举个例子：一个人能熟练的讲德语，但是他从来没有学习过德语，也没有去过德国，并且也没有和讲德语的人交流过。

Xenoglossy (/ˌziːnəˈɡlɒsi, ˌzɛ-, -noʊ-/), also written xenoglossia (/ˌziːnəˈɡlɒsiə, ˌzɛ-, -noʊ-/), sometimes also known as xenolalia, is the putative paranormal phenomenon in which a person is able to speak or write a language he or she could not have acquired by natural means. The words derive from Greek ξένος (xenos), "foreigner" and γλῶσσα (glōssa), "tongue" or "language". The term xenoglossy was ostensibly coined by French parapsychologist Charles Richet. Stories of xenoglossy are found in the Bible, and contemporary claims of xenoglossy have been made by parapsychologists and reincarnation researchers such as Ian Stevenson. There is no scientific evidence that xenoglossy is an actual phenomenon.
