Pronunciation

Hi,

Just as one is supposed to be careful to pronounce the words of Shema properly, one is also supposed to pronounce all words from Tanach carefully, whether in prayer or in learning Torah. However, one who is studying, and who finds that fine attention to pronunciation damages his learning, may reduce his attention to pronunciation.

(Rivivot Ephraim 1:54)

Have a great day,
Mordechai

Changing accents in prayer

Hi,

One who has a family tradition of using Ashkenazi or Sephardi pronunciation of Hebrew should not veer from that tradition when praying.

(Rav Moshe Feinstein, Igrot Moshe Orach Chaim 3:5)

Have a great day,
Mordechai
