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.

Stress Patterns

Cineradiographic and spectrographs analyses were performed to study the speech production of a subject who presented the classical neurologic signs of cerebellar lesion and who had speech characteristics like those that have been reported for ataxic dysarthria. These analyses were conducted with special attention to the deviant perceptual dimensions that have been described for ataxic speech. Examination of the cineradiographic and spectrographic records revealed conspicuous abnormalities in speaking rate, stress patterns, articulatory placements for both vowels and consonants, velocities of articulator movements, and fundamental frequency contours. In general, our physiological and acoustic observations of ataxic dysarthria were compatible wth existing perceptual descriptions of this condition. The data for the subject are discussed in the light of current hypotheses concerning cerebellar participation in the regulation of skilled movement. Particular suggestions are made concerning the nature of the neuromuscular abnormalities that may underlie the aberrant motorics of ataxic dysarthria.

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.

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.

Treatment Sequences

Treatment programs of four improving ataxic dysarthric speakers are reviewed. Treatment sequences were based on two overall measures of speech performance—intelligibility and prosody. Increases in intelligibility were initially achieved by control of speaking rate. A hierarchy of rate control strategies, ranging from a rigid imposition of rate through rhythmic cueing to self-monitored rate control is discussed. As speakers improved their monitoring skills, a compromise was made between intelligibility and rate. Normal prosodic patterns were not achieved by the ataxic speakers due to difficulty in precisely coordinating the subtle fundamental frequency, loudness and timing adjustments needed to signal stress. Three of the four subjects were taught to use only durational adjustments to signal stress. In this way, they were able to achieve stress on targeted words consistently and minimize bizarreness which resulted from sweeping changes in fundamental frequency and bursts of loudness. The need for further clinically oriented research is discussed.
