1.5 House and the elaboration of overt and covert translation
House (1977) is in favour of semantic and pragmatic equivalence and argues that ST and TT should match one another in function. House suggests that it is possible to characterize the function of a text by determining the situational dimensions of the ST. In fact, according to her theory, every text is in itself is placed within a particular situation which has to be correctly identified and taken into account by the translator. After the ST analysis, House is in a position to evaluate a translation; if the ST and the TT differ substantially on situational features, then they are not functionally equivalent, and the translation is not of a high quality. In fact, she acknowledges that “a translation text should not only match its source text in function, but employ equivalent situational-dimensional means to achieve that function” (ibid.:49).
Central to House’s discussion is the concept of overt and covert translations. In an overt translation the TT audience is not directly addressed and there is therefore no need at all to attempt to recreate a ‘second original’ since an overt translation ‘must overtly be a translation’ (ibid.:189). By covert translation, on the other hand, is meant the production of a text which is functionally equivalent to the ST. House also argues that in this type of translation the ST ‘is not specifically addressed to a TC audience’ (ibid.:194).
House (ibid.:203) sets out the types of ST that would probably yield translations of the two categories. An academic article, for instance, is unlikely to exhibit any features specific to the SC; the article has the same argumentative or expository force that it would if it had originated in the TL, and the fact that it is a translation at all need not be made known to the readers. A political speech in the SC, on the other hand, is addressed to a particular cultural or national group which the speaker sets out to move to action or otherwise influence, whereas the TT merely informs outsiders what the speaker is saying to his or her constituency. It is clear that in this latter case, which is an instance of overt translation, functional equivalence cannot be maintained, and it is therefore intended that the ST and the TT function differently.
House’s theory of equivalence in translation seems to be much more flexible than Catford’s. In fact, she gives authentic examples, uses complete texts and, more importantly, she relates linguistic features to the context of both source and target text.
