and that she wanted to care for her husband at home with the hope that he would be more comfortable with his family. Although tearful about his condition and somewhat nervous about the prospects of caring for him at home, she was eager for his discharge and relieved by the knowledge that we would be available to provide help and support. She was then instructed in colostomy and catheter care by the nurse; she also met with the social worker in order to file application for financial assistance. J. R. was then discharged to home.

N2 - EMG-based VAD is proposed. It is generally known that EMG signals are not affected by acoustic noise and preceding voice. Robust but preceding detection of speech can be expected by using these features. The proposed method extracts one VAD parameter to judge speech or silence from among n EMG signal channels. Experiments are performed to confirm the effectiveness of the proposed method. The results show that some EMG signals reliably precede voice by 30ms or more. Compared with conventional audio VAD, the proposed method seldom drops the speech head and the method's performance is relatively insensitive to background noise.
