הַקּוֹרֵא אֶת שְׁמַע וְלֹא הִשְׁמִיעַ לְאָזְנוֹ – יָצָא.
רַבִּי יוֹסֵי אוֹמֵר: לֹא יָצָא.
קָרָא וְלֹא דִּקְדֵּק בְּאוֹתִיּוֹתֶיהָ –
רַבִּי יוֹסֵי אוֹמֵר: יָצָא;
רַבִּי יְהוּדָה אוֹמֵר: לֹא יָצָא.
הַקּוֹרֵא לְמַפְרֵעַ – לֹא יָצָא.
קָרָא וְטָעָה – יַחֲזֹר לִמְקוֹם שֶׁטָּעָה.
One who recites Shema but doesn't make it audible to his ear - has fulfilled his obligation. Rabbi Yosei says: he has not fulfilled his obligation. One who recites but does not articulate each letter properly: Rabbi Yosei says: he has fulfilled his obligation. Rabbi Yehuda says: he has not fulfilled his obligation. One who recites out of order - has not fulfilled his obligation. One who recites and makes a mistake - should return to the place where he made the mistake.
