1. A device for generating speech information signal, comprising:

  • input means for generating a first control signal and a second control signal that are mutually exclusive in time;

    storage means for storing natural speech information in the form of first time-sequential strings each having one or more distinct words;

    speech generating means for, under control of said second control signal, generating synthetic speech information as further time-sequential strings each having one or more further distinct words; and

    multiplexing means coupled to said storage means and to said speech generating means for receiving said natural speech information and said synthetic speech information and for selectively outputting on a word-by-word basis one of said natural speech information and said synthetic speech information in response to said first control signal and said second control signal, respectively, to generate said speech information signal, while being blocked from switching-over between said storage means and said speech generating means other than at the end of said time-sequential string.
