Abstract This paper presents a framework for the definition of monotonic repair rules on chart items and Lexicalized Tree Grammars. We exploit island representations and a new level of granularity for the linearization of a tree called connected routes. It allows to take into account the topology of the tree in order to trigger additional rules. These local rules cover ellipsis and common extra-grammatical phenomena such as self-repairs. First results with a spoken language corpora are presented.
