Commentary for Berakhot 29:9

<big><strong>גמ׳</strong></big> מאי טעמא דר' יוסי משום דכתיב שמע השמע לאזנך מה שאתה מוציא מפיך ות"ק סבר שמע בכל לשון שאתה שומע

GEMARA What is R. Jose's reason [for declaring that unless the Shema' is read audibly the requirements of the law have not been fulfilled]? Because it is written, "Hear O Israel," i.e. let thine ear hear what thou issuest from thy mouth. And the first Tanna ? He holds that "Hear" [means that the Shema' may be read] in any language which thou hearest.
