Please provide sources for those who say that when one is somech geulah to tefillah, one should say "Yisroel" silently rather than out loud, which might require a bracha.
Answer:
Hello,
See Shulchan Aruch O:CH 66-7, with Mishna Berura and Piskei Teshuvos 66-10 for different opinion regarding this.
Best wishes
