The research reported here was conducted while I was staying at ATR Interpreting Telephony Research Laboratories, and then at ATR Interpreting Telecommunications Research Laboratories, as visiting researcher from GETA, IMAG, UJF&CNRS, France. I would like to heartly thank ATR for its constant support and very favorable research environment; and its members, from President through supervisors through researchers through secretaries to security personal, for all the personal help which they extended to me in so many ways at so many occasions.
