Voice Fundamental Frequency

An acoustic analysis of certain aspects of voice fundamental frequency (F o ) in response to auditory clicks may provide a tool for studying short-latency auditory-laryngeal reflexes in humans (Sapir, McClean, & Larson, 1983). The purpose of this investigation was to compare 18 adult male stutterers' and 19 adult male nonstutterers' auditory-laryngeal reflexes. Subjects sustained phonation at constant pitch and intensity levels while receiving bilateral auditory click stimuli. F o signal averages were generated and measured. Data analyses indicated that there were no differences between stutterers and nonstutterers with respect to the frequency of reflex occurrence. Also, there were no significant group differences with respect to the mean reflex temporal measures or the variability of the reflex temporal measures.

Voice Fundamental Frequency

Fundamental frequency perturbation (jitter) during sustained vowel phonations of speakers under topical anesthesia of the larynx was investigated for five adult males. The results showed that the average jitter was significantly greater under the anesthesia than normal conditions, and that the jitter difference between the two conditions was more prominent at high frequency phonations. Implications of these data for tactile and proprioceptive feedback in phonatory frequency control are discussed.

Normal Speaking

An intensive study of a normal-speaking subject, proficient in the use of buccal speech, was conducted. With respect to voice fundamental frequency variability, phonation time, and speaking rate his buccal speech characteristics compared favorably with those reported for excellent esophageal speakers. However, the reduced intelligibility of his buccal speech on rhyme-test words, the high average fundamental frequency of his buccal voice, and his conspicuous buccal gestures during speech represent distinct vocal liabilities.

Speaking Fundamental Frequency

Spontaneous speech samples of 27 children with trisomy-21 type Down’s syndrome and 66 normal children were tape-recorded and analyzed for mean fundamental frequency, standard deviation, and range. Results indicate that the mean speaking fundamental frequency (SFF) level for the sample of children with mongolism was significantly higher than the mean SFF level for the control sample. Approximately 50% of the children with mongolism had mean SFF levels exceeding the highest mean SFF level of their matched controls. In only two cases did the mean SFF for a child with mongolism fall below the mean SFF level for control children of the same age and sex. No child with mongolism exhibited a mean SFF level below the lowest mean SFF for any control subject. The subject in question is the clinical observation that children with mongolism typically have low voice fundamental frequency levels.
