The value of the spoken word is way overrated, usually by those doing the speaking.
I've read that something like 7% of communication takes place verbally. I'd bet in the martial arts it's even less. So will you be missing that much? Witness how many times you've been told to do something but don't get it whereas if you feel it you get it?
Then there's the times where I wished I could turn off the monotonous sound found at a dojo. Some sensei just won't shut up. I know I'm supposed to glean every bit from their pearly wisdom but Keyrist maybe they could bullet point, give it to us after class or put it on their web site. When every response is "uh huh!" the folks have stopped listening but to some it's a sign they are on a roll.
I'm with Jun, give it a week and see what happens.
