If you pay attention to how the voice interface is used in Star Trek (TNG and upwards), it's basically exactly what the article is saying - it complements manual inputs and works as a secondary channel. Nobody is trying to manually navigate the ship by voicing out specific control inputs, or in the midst of a battle, call out "computer, fire photon torpedoes" - that's what the consoles are for (and there are consoles everywhere). Voice interface is secondary - used for delegation, queries (that may be faster to say than type), casual location-independent use (lights, music; they didn't think of kitchen timers, though (then again, replicators)), brainstorming, etc.
Yes, this is a fictional show and the real reason for voice interactions was to make it a form of exposition, yadda yadda - but I'd like to think that all those people writing the script, testing it, acting and shooting it, were in perfect position to tell which voice interactions made sense and which didn't: they'd know what feels awkward or nonsensical when acting, or what comes off this way when watching it later.
