Mode Tracking

This study was conducted to (a) study the ability of young adult subjects to track target signals with the lower lip, jaw, or larynx, (b) examine subjects’ abilities to track different sinusoidal frequencies and unpredictable target signals, and (c) test notions of response mode and predictive mode tracking reported for nonspeech structures by previous authors (e.g., Noble, Fitts, & Warren, 1955; Flowers, 1978). Twenty-five normal speakers tracked sinusoidal and unpredictable target signals using lower lip and jaw movement and fundamental frequency modulation. Tracking accuracy varied as a function of target frequency and articulator used to track. The results quantify the visuomotor tracking abilities of normal speakers using speech musculature and show the potential of visuomotor tracking tasks in the assessment of speech articulatory control.

The Difference

Terompong is a type of gamelan in Bali Province. This gamelan is commonly used in traditional ceremonies in Bali, especially the Dewa Yadnya and Pitra Yadnya. The terompong are striking instruments, where the bat is made of wood. The terompong is also a two-octave musical instrument composed of 10-12 small metal gong blocks. The gong blocks are arranged parallel, which makes the gong difficult to carry and has to stay somewhere if someone want to play. Of course, with this situation people find it difficult to learn the terompong because they are quite large and heavy. This problem could be solved by replace the original terompong with synthetic terompong. The synthesis referred here the synthesis of sound. In performing sound synthesis, the method used is Frequency Modulation (FM). The result of the synthesis carried out where the difference between fundamental frequency of the original tone and the synthesis tone is almost close to zero. The sound produced almost follows the original sound, but it can't follow the sound of metal being hit with a wooden club.

Neutral Conditions

AbstractThis article presents the results of a study on articulatory and acoustical correlates of contrastive focus in French in five children aged 4 and 5 and five adults. The speakers repeated the sequence [baba] in two prosodic contexts: neutral conditions and contrastive focus. The acoustic signal and the trajectories of three sensors placed on the subjects’ upper lip, lower lip, and chin were recorded using an Optotrak system. Articulatory movements were analyzed for the two syllables in the sequence, in each of the two prosodic conditions. Formant measurements, sound intensity, fundamental frequency, and acoustic duration of the segments were also extracted from the acoustic signal. The results show that the effects of contrastive focus are smaller in the children than the adult speakers. The results are interpreted in light of recent theories on the emergence of spoken language in children.

The Subject ◽  
Male Subjects

Five young adult male subjects with normal larynxes were recorded as they sustained phonation during one normal and three drug conditions. The vocal tasks included obtaining the total fundamental frequency range, tone-matching ability, and vocal fry production, and were performed by the subject (1) before drugs, (2) following injection of a tranquilizer-narcotic premedication, (3) after topical anesthesia of the larynx, and (4) during a drug-recovery period. Results showed no significant differences between conditions on any of the measures of sustained phonation. It was concluded that neither depressed cortical function nor sensory deprivation of the laryngeal mucosa alters the subject’s phonatory capabilities essential to the performance of the selected vocal tasks.

Viable Approach

Assessment of speech-muscle function during nonspeech tasks may provide an important component in the clinical evaluation of speech-motor disorders. Various methodological problems have limited the value of such data in the past. The goal of the present study was to evaluate a set of instrumental, objective procedures for assessment of the nonspeeeh performance capabilities of different speech-muscle systems. Subjects included 10 nonimpaired adults and a diverse group of 6 adult dysarthric individuals. Each subject performed visuomotor tracking of a 0.6-Hz sinusoidal target with the lower lip, jaw, larynx, and respiratory systems. Cross correlation and phase data were used to describe tracking performance. The nonimpaired subjects showed consistently high cross correlations with little phase shift. The dysarthric subjects showed a wide range of tracking performance which was generally consistent with their overall levels of speech performance and levels of neurological impairment. Differential levels of performance were noted across speech subsystems in some dysarthric subjects. In general, the results suggest that visuomotor-tracking paradigms provide a viable approach to clinical evaluation of speech-muscle function in nonspeech tasks.
