Generally speaking, Novardokers encouraged public speaking. They used to say “Lech Reid” i.e. “go and speak!” (Reid means “speak” in Yiddish). They would even say “red garbage uber red!” Speak “garbage” you don’t have to succeed in your speech and get Kavod. The main thing is to break your weakness and not worry so much what people think of you (which can Chas V'shalom paralyze a person from using his abilities). With practice and encouragement from the Rosh HaVaad, you break the Avoda Zara of fear of humans.
However, Novardok was very broadminded and sometimes the opposite is true. I knew very outgoing Novardokers who were always speaking in public (even without being asked to speak!) Like R’ Koppel Pasternak Zatzal. And some were Davka quiet and never spoke in public like R’ Yisroel Movshovitz Zatzal, who never spoke in public (but privately he would spend hours talking with the Bachurim and being M'chazek them. He was indeed much loved by everyone).
An old Novardoker was at a Simcha, and he complimented a Chashuva person who just sat there without speaking: “This man is good. No speaking for him!” As always, you need a Rebbe to guide you.
