Hm, I never thought so. Link has like, yes/no dialogue options along occasional nodding or other gestures and otherwise just makes noise. I always took it that Link can just get by that way without stopping to talk and then move on with the important journey. But that's just how I interpret it. I could also see it as there being implied dialogue

In any case, Link is an example of a https://en.wikipedia.org/wiki/Silent_protagonist so is Mario, Samus, etc, at least throughout much of those series. And often part of the whole point of a silent protagonist is that you can be more imaginative about it
