The Talmud teaches that no meal or celebration is complete without words of Torah spoken to focus and sanctify the proceedings. Thus there is a longstanding custom for the groom to offer words of Torah at the tish. Some commentaries, notably the Shulchan HaEzer, note that on the day of their wedding bride and groom are like royalty and so it is fitting for them to hold forth with their own declarations and teachings. Certainly if the bride is a woman of Torah learning and she wishes to share a divar torah, a word of Torah, she may. If the groom does not wish to speak words of Torah or insight, that is fine since his comfort level and the bride's comfort is certainly more important.

In most circles today, if the groom or bride are going to share words of Torah they are interrupted after a few sentences with shouts of mazel tov and a round of wedding song. The purpose of this custom is twofold. First, even if the groom is learned he may not be in any state to concentrate on the lecture he is about to give, and so by beginning a speech it is assumed he is wise but he does not need to be well prepared. Second, he is interrupted so as not to embarrass grooms who are not learned and would not be able to share words of Torah. Thus all grooms or brides are interrupted and all are viewed on their wedding day as men and women of wisdom.
