Fundamental frequency perturbation (jitter) during sustained vowel phonations of speakers under topical anesthesia of the larynx was investigated for 5 adult males. The average jitter was significantly greater under the anesthesia than normal conditions and the jitter difference between the 2 conditions was more prominent at high frequency phonations. Tactile and proprioceptive feedback in phonatory frequency control are discussed.
