Vibrato rate and vibrato extent were acoustically assessed in 12 classically trained female singers before and after 25 minutes of vocal warm-up exercises. Vocal warm-up produced three notable changes in vibrato rate: (1) more regularity in the cyclic undulations comprising the vibrato rate of a note, (2) more stability in mean vibrato rates from one sustained note to the next, and (3) a moderating of excessively fast and excessively slow mean vibrato rates. No significant change was found for vibrato extent. The findings indicate that vocal warm-up may regulate vibrato rate. Thus tone quality, which is strongly linked to vibrato characteristics, may undergo positive change as a result of vocal warm-up.
在进行 25 分钟的声乐热身练习前后，对 12 位受过古典音乐训练的女性歌手的颤音率和颤音幅度进行了声学评估。声乐热身练习对颤音率产生了三个显著的变化：（1）音符的颤音率所包含的周期性波动更加规则；（2）从一个持续音符到下一个音符的平均颤音率更加稳定；（3）过快和过慢的平均颤音率得到缓和。颤音幅度没有显著变化。研究结果表明，声乐热身练习可能会调节颤音率。因此，与颤音特征密切相关的音质可能会因声乐热身练习而发生积极的变化。
