If you want to get a deeper voice instantly, two things you can look into are your posture and breathing. Poor posture will without a doubt impede on the quality and sound of your voice. Making sure you are not hunched when you talk (you have to make a conscious effort to do this – many of us hunch our backs out of habit, so you have to be pay extra attention to your posture when you’re talking) will open up your diaphragm and allow air to move more freely, and in turn you will instantly be able to speak with a clearer, deeper voice.
