toneless
Lacking vocal variation
Toneless describes sound lacking variation, expression, or resonance.
A toneless voice is flat and monotonous, conveying no emotion: She answered in a toneless whisper.
The word applies to speech, singing, or instruments that sound dull or dead—missing the warmth or color that gives sound character.
