This paper describes BCI (Brain-Computer-Interface) using ERP (Event-Related-Potential) evoked by auditory stimulations. BCI have been expected to be a useful communication aid for persons in totally locked-in state. However, there is no effective communication tool using BCI. Survey of ALS (Amyotrophic Lateral Sclerosis) patient's lifestyles and their needs for communication aids was conducted. Based on the result of this survey, we decided to develop BCI using ERP evoked by auditory stimulations with Japanese letters. For the first step, 3 choice paradigms were tested. And then, Japanese stimulations were tested. The results showed that there are possibilities to choose one from 3 stimulations or more, and to use Japanese letters instead of simple auditory stimulations.
