'Diào sǎng zi' literally means 'lift the voice' — 'diào' conveys the idea of raising or lifting, 'sǎng' refers to the voice or throat, and the suffix 'zi' makes it a colloquial noun-like verb phrase. It describes the daily vocal warm-up exercises practiced by singers, opera performers, and speech professionals to strengthen vocal cords, improve pitch control, and enhance resonance.

This term is deeply rooted in traditional Chinese performing arts, especially Peking opera, where rigorous vocal training begins early each morning. While it can be used broadly for any systematic voice practice, it carries a cultural nuance of disciplined, ritualized preparation — not just casual humming or singing along. The activity often involves sustained tones, scales, and articulation drills, typically done outdoors or in open spaces for optimal acoustics and breath control.
