If there is no singing at the entrance, the antiphon in the Missal is recited either by the faithful, or by some of them, or by a lector; otherwise, it is recited by the priest himself, who may even adapt it as an introductory explanation (cf. above, no. 31).
To me it seems inane to say that the "unofficial" translations could be sung (e.g. SEP) but not spoken (particularly when the priest may adapt them at his whim). Since we aren't renewing our disposable missal subscription, then, we would just have the congregation speak the translations as they appear in the hymnal.
