This article describes a central part of the syntactic schemes that are currently used in the ongoing annotation of a French spoken corpus. Based on the Aix School grid analysis of spoken French, the notion of « pile » is introduced, allowing for an elegant description of various paradigmatic phenomena like disfluency, reformulation, apposition, instanciation, including question-answering and colon effect, and different types of coordination. Piles naturally complete dependency annotations by modeling non-functional relations between phrases.
