—DAF Effect from the Viewpoint of External and Internal Feedback Models for Speech Control (I) —Teruyo Fukawa1980 Volume 21 Issue 2 Pages 103-108

JOURNAL FREE ACCESSDelayed auditory feedback (DAF) effect was studied with the reading materials of different levels in familiarity, i.e. meaningful words and non-sense syllables, practiced and not practiced. Normal subjects with no stuttering habits (30 boys and 30 girls of the 6th grades of a primary school were equally divided into three groups) read the given materials under NAF (normal auditory feedback) and DAF conditions for testing DAF condition and fluency. The materials for Group 1 were 9 familiar meaningful words, while those for Group 2 and Group 3 were 9 unfamiliar non-sense syllables respectively. Group 3, however, was tested after ten times practice in reading the materials. DAF effect was defined by the formula, 1- CMR under DAF/CMR under NAF (CMR was the correct morae rate of reading per second) . DAF effect in Group 1 was found significantly less than that in Group 2 but there was no significant difference between Groups 2 and 3. The results were discussed and evaluated external and internal feedback models for speech control.View full abstractDownload PDF (633K) -
Observation by Dynamic Palatograph and CineradiographKeiko Okazaki, Takuya Onizuka, Masako Abe, Masayuki Sawashima1980 Volume 21 Issue 2 Pages 109-120

JOURNAL FREE ACCESSThe palatalized articulation for the dental and alveolar sounds has been reported as a type of articulation errors in the cleft palate speech. In the present paper, articulatory tongue gestures for this particular type of error were observed by the use of dynamic palatograph and cineradiograph.
The subjects were 9 postoperative cleft palate patients with this type of articulation error, 5 males and 4 females, ranging from 5 to 23 years old. Among the 9 subjects, 2 were observed by cineradiograph and 8 by dynamic palatograph.
The result revealed the tongue gestures were characterized by the articulatory contact of the back of the tongue, instead of the tip or the blade, to the posterior end of the hard palate. The tongue-palate contact was clearly different from that for the normally palatalized /s/ which is represented as [∫] in Japanese. Sound spectrograms of the fricative sound produced by this abnormally palatalized articulation showed a marked decrease in the noise energy in the high frequency range as compared to the [s] or [∫] . The results supported the previous report where characteristic features of this articulation error were described mainly by auditory analysis and by limited visual observations from the mouth opening.
Articulation training was administered to the patients in order to replace the faulty articulation by the correct gestures for the dental and alveolar sounds. The tongue-palate contact pattern which was nearly identical to that in normal subjects was observed when the patient reached the clinically acceptable goal.View full abstractDownload PDF (1575K) -
—A Preliminary Report—Seiji Niimi, Zyun'ici Simada1980 Volume 21 Issue 2 Pages 121-125

JOURNAL FREE ACCESSThe purpose of this paper is to discuss the possibility of application of ultrasonic technique to observe tongue shape. One of the advantages of ultrasonic technique is harmlessness to the human subject. Beside this, the frontal section of the tongue which is the difficult object for ordinary X-ray photo can be visualized. Sagittal contours of the tongue for five Japanese vowels observed by this method are well corresponding to those by X-ray technique. Contours of the frontal section at around the tongue root show a groove formation during /i/, /e/, and /o/ production.
For all of these three vowels, the genioglossus muscle shows higher activity. Therefore, the observed groove may be representing the inserting portion of the genioglossus muscle.
Since the apparatus we used in this study is designed and developed for the clinical purpose, for example to examine the thyroid tumor, the data we got had limited informations especially, the visualized area was narrow. But if we can use the sector type porbe instead of the linear type, we might have the wider area to be observed.
The ultrasonic apparatus would be appropreate for observation of the tongue shape.View full abstractDownload PDF (1321K) -
