Could you please keep your voice down?
Student or Learner
Please tell. What is the opposite of "could you please speak a bit louder". Is it "Softer"?
Please speak a bit more quietly.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
Also: could you please lower your voice.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
Is "please speak in a soft voice" OK?
