Abstract: This paper focuses on two commonly-made claims about the
        utility of speech input: (1) It is faster than typed input;
        and (2) it also increases user productivity by providing an
        additional response channel.  These claims are investigated,
        both through a review of research, and through an empirical
        evaluation of speech input.  The research review supports
        both claims.  Further, it suggests that speech input will be
        more beneficial when users are engaged in multiple tasks
        mapped onto multiple user-response modalities, and when
        speech is used in tasks characterized by short transactions
        of a highly interactive nature.  The empirical study
        evaluated the utility of speech input in the context of a
        VLSI chip design package, and compared speech to typed,
        full-word input, single keypresses, and mouse clicks.
        Results supported the benefits of speech input over typed,
        full-word commands, and to a lesser extent, single
        keypresses.  For the restricted set of commands that could
        be accomplished with mouse clicks, speech input and mouse
        clicks were equally efficient.  These results are
        interpreted in terms of a general "ease vs expressiveness"
        guideline for assigning modalities to tasks in a user
        interface.
