I found this in the Rashi on Ki Seitzei (Deuteronomy 22:16): 



>And the girl’s father
> shall say [to the elders]: [The father, but not the mother.] **This
> teaches us that a woman is not permitted to speak in the presence of
> her husband [when others are present]**. — [Sifrei 22:91]  	 ואמר אבי
> הנערה: מלמד שאין רשות לאשה לדבר בפני האיש:


I had never heard of this idea in Jewish law. Does such a halacha exist, and what is its status today? I am most interested in sources which discuss whether and to what extent this particular detail must actually be observed in our era.
