To speak or act "tonelessly" means doing so without any inflection, emotion, or variation in pitch. It's as if the voice is a flat, unchanging line. Think of a robot reciting lines from a script, devoid of feeling. It's the opposite of speaking with passion or enthusiasm. It can suggest boredom, indifference, or a deliberate attempt to hide emotions. Imagine a monotone beep: 🔈 that's toneless.
