Previous studies altered the gain and timing of auditory feedback in singers producing vibrato and showed inconsistent effects on the extent and rate of </span></span><em>f</em><sub>o</sub><span> modulation, which may have been related to small sample sizes or limited analyses.

Acoustical analyses measured changes in the extent and rate of <em>f</em><sub>o</sub> modulation in the masked and delayed trials relative to control trials.
