There are at least two ways to go about this without changing the Mode. Word is used as a placeholder for the actual command/word in this answer.
Just say "word space bar". It will insert a space after the word without triggering the command.
Or use a spoken form for the word, e.g. "word as word".
Or alter the command to present you with a choice between the word and the command. This requires some fairly Advanced Scripting.
Just type the word.
