A portable electromotive Kana-typewriter was developed as a communication method for dysarthric patients. As the size of this machine is 215×90×30mm, it is easy to carry in the pocket or bag. This machine has 50 keys (Kana-letters) with a thermal print system. Using this typewriter, the dysarthric patients who had almost no speech output and showed only a gesture of“yes”or“no”reaction, could express their ideas correctly and communicate actively with other people. It was believed that the device was very helpful for the dysarthric patients. But the effectiveness of this machine was greatly dependent on their intelligences, vocations and their motivations and so on. Other technical problems are the sharpness of the printed letters and the size of the apparatus to be carried more conveniently. By improving these technical points, utility of this Kana-typewriter will be multiplied and it will be useful as an aid of communication for severe dysarthric patients.
The present study was designed to investigate the process of syntactic recognition of heard sentences in aphasics, especially the effect of changes in word order on syntactic recognition. Comprehension performance of 27 aphasics was studied by using two types cf active and passive test senteces; sentences having basic word order and sentences having converse word order. The results comfirmed earlier observations reporting that comprehension of sentences having converse word order was significantly poorer than comprehension of sentences having basic word order. It was suggested that there were two strategies employed by aphasics; the word order strategy and the particle strategy. Subjects were classified into four groups according to ability to use the strategies. The correlation between the syntactic comprehension and the other variables was discussed.
In order to investigate relationship between quality of voice and laryngeal adjustment, electro-myographic recordings were made with three intrinsic laryngeal muscles, i.e. the cricothyroid, lateral cricoarytenoid and vocalis muscles, when a tenor sang in different qualities of voice with six different“Placings”which had been defined by Husler. Mean air flow rate was also measured for some singing samples. The results led us to the following conclusions. 1. Among the placings which fit rather low pitches, the placing No.2 is accompanied by the heviest adjustment whereas the No.3b is associated with the lightest adjustment. 2. Among the placings suitable for rather high pitches, the placing No.6 requires heavy adjustment while No.4 and No.5 are of light adjustment (falsetto) . 3. Although there are definite relationship between the placing and laryngeal adjustment, the placing appears to be also a matter of resonance to a certain extent.
