The fundamental frequency and jitter of the voice was measured by electroglottography in 71 children between the age of 7 and 15 years. In this series of children the fundamental frequency and jitter did not depend on the gender. The median (range) fundamental frequency was 244 (182-331) Hz in girls and 250 (205-293) Hz in boys. It decreased with increasing height (r = -0.59; P < 0.0005) and age (r = -0.57; P < 0.001). The median jitter ratio was 9.7 (1.6-33.3) in girls and 10.3 (2.0-4.3) in boys. The jitter ratio was negatively related to height (r = -0.31; P < 0.05), but not to age.
采用电子声门图法对71名7至15岁儿童的嗓音基频和抖动进行了测量。在这组儿童中，基频和抖动并不取决于性别。女孩的中位（范围）基频为244（182 - 331）Hz，男孩为250（205 - 293）Hz。它随身高增加而降低（r = -0.59；P < 0.0005），并随年龄增长而降低（r = -0.57；P < 0.001）。女孩的中位抖动率为9.7（1.6 - 33.3），男孩为10.3（2.0 - 4.3）。抖动率与身高呈负相关（r = -0.31；P < 0.05），但与年龄无关。
