Try speaking through your mouth, rather than your nose. It's possible to get a deep nasal voice, but it sounds more masculine if you speak through your mouth. To deepen your voice, you'll want to try and lower your pitch. To do this, relax your throat as much as possible, to avoid tightening your vocal cords.
Is there an app to make your voice sound like a man?
