imo, to attend a wedding w/o a speech, is a bit rude. but that's of course, my own opinion.
to date have not attended any that does not have it. doesnt necessary need both to talk. i've been to weddings where only the groom/bride talks.

my best friend's wedding was an animation version of thank you speech! I mean if you are worried about stage frights etc, such pre-recorded speeches can do the trick.
for me, wedding speech is important as it's my way of saying thanks to my guests and of course both families, relatives especially, the in-laws.
hmmm, if u ask me, sometimes both hubby and i still feel like we're not married! like still dating probaby because we have been staying together even before marriage.
but of course, after marriage, it does feels different. personally, i find myself becoming more tolerant of my hubby and vice versa.
don't know leh, maybe it's just me, i tot i did 'mature' in some way. plus, now, many times we mus think of his family too.
cause he stays with me, we mus constantly make arrangements to go back and sleep over at his place, dinner at his place etc.
then of course, the bugging question .. baby..
