I dont understand the pronunciation? It soundes like hes saying "תולאחים" or something
A final -d is quickly followed by an initial sh-; the result is something like a -tsh-/-tch-.
I agree, I can't hear any "sh" sound at all. Without the text I never would have known what the Hebrew was.
I used samech instead of shin. Sometimes they say "you have a typo" for simple spelling mistakes and sometimes they say it's just wrong. It would be nice if they were more consistent.
