    We investigated effects of the fluctuation of fundamental frequency (F0) on the identification of pathological of two kinds of voice qualities, rough and voice tremor.
    Based on our previous report, a frequency modulation (FM) model was used for the F0 series generator, assuming that the fluctuation of F0 for the pathological rough voice is a single sinusoid. Synthetic vowels /a/ with frequency modulated F0 fluctuation were generated for systematic combination of two modulation parameters, i.e., modulation frequency (fs) and modulation index (ma) .
    Six subjects (4 laryngologists and 2 voice scientists) were used to listen to the syntheticvoices.100 stimuli (10 different values of fs times 10 different values of ma) were presented in random order.
    For this identical set of stimuli, all categories were tested one at a time. The subjects were instructed to answer yes/no for a specific category out of the three categories, rough, voice tremor and normal.
    The results were as follows.
    (1) Each of the three categories was clustered.
    (2) The boundary separating pathological from normal in terms of the amplitude of F0 fluctuation Δ F0 (=ma×fs) lies between 1.4Hz and 2.2Hz,
    (3) The boundary between rough and voice tremor lies at the fluctuation frequency fs-10Hz.

    This is a case report on a patient who suffered severe deficit in writing of kanji characters resulting from a cerebrovascular accident. The patient was a 62-year-old right-handed woman with cerebral hemorrhage who showed severe deficit in writing of kanji characters both spontaneously and under dictation. The findings of MRI revealed lesions in the left posterior part of the middle and inferior temporal cortex and white matter. The results of a dictation test of 221 kanji characters that are learned in the 1st and 2nd grades of elementary school were as follows : (1) the number of totally correct answerswas only 54 (24.4%) ; (2) the percentage of correct answers decreased with the number of strokes in the kanji ; and (3) the error type observed most frequently was “error irrelevant to target character”, of which “partial response” and “neologic character” were evident in particular. In addition, regarding the kanji characters she was unable to write correctly, the patient showed capability to discriminate visually between correct ones and false ones, as well as to understand their meaning. Training in kanji writing was administered mainly using a copying method from 2 to 17 months post onset. Through a 15-month treatment, the following findings were obtained : (1) the number of totally correct answers rose to 162 (73.3%) ; (2) the tendency toward difficulty relating to number of strokes declined ; (3) the number of “errors irrelevant to target character” decreased greatly ; and (4) treatment efficacy extending to untrained characters remained low.
