In this paper, the effectiveness of the replacement of the function key by the voice input in four kinds of text editing tasks was verified.The key input and two kinds of voice inputs were used in the experiment.Concerning the voice input, the mode (Voice 1) which does not prespecify the range of editing and the position of carrying out the command and the one (Voice 2) which prespecifies them were selected.For all types of experiments, the text editing was repeated four times (blocks) at each input mode.With respect to both the editing error and the percent correct recognition, no significant differences were found among input modes and among blocks for each editing task.Both the subjective rating for the ease of editing and the mean processing time for Voice 1 were the best for all editing tasks.The usability for Voice 2 was nearly as same as that for the key input.It is concluded that the voice input mode which replaces the function key corresponding to more than four or five key inputs by the voice input (Voice 1) is more effective.
