The aim of recent work by the authors has been to increase the usability of a speech driven interface. This paper addresses an area that could contribute significantly to the usability of the interface, that of mixed mode input, Using the standard word processor WordPerfect, this paper investigates how speech can be used in conjunction with keyboard for the three task categories, text creation/editing, wordprocessor commands, and navigation. We felt that for certain task categories the best use of speech was not to map keystrokes, but to apply it to higher level task models. The experiments described compare the use of speech for navigation and commands only, in conjunction with total speech input, and total keyboard. Keywords: Speech, Word Processing, Usability, Task Models
