Funny tone of voice

When talking to others, you should think more and think more about other things. Your tone of voice should be lively, your expression should be exaggerated and rich, you should watch more classic movies and remember other people's classic dialogues. Sometimes you can change some proverbs or something, and sometimes you can use them directly.

For example, when someone asks you why you don't speak, you can use: Silence is golden, I can't speak, and anything like that is more useful to say in silence than in voice.

In short, just use your head and practice more.
