Excessive Closure

过度闭合

Vocal Science Principle

Excessive vocal fold closure — the vocal folds are overly tense, producing a pressed, tight sound.

Detection criteria:

NAQ (Normalized Amplitude Quotient) below threshold (default < 0.1) and NAQ > 0

Very low NAQ indicates the vocal folds are pressing together too tightly, restricting vibration and producing a strained quality.

过度闭合会导致声音紧绷、缺乏灵活性，需要放松喉部
