A new corpus has been recorded. The transcription and alignment of this “MTX-Corpus” is completed. One aim of the project is to analyze conversational feedback at different interactional situations (spontaneous conversation, task-oriented dialogue and an intermediate condition). While working on the French Map Task we figured out that hit will be interesting to vary the recording condition (remote vs. face-to-face) as it has actually be done on the Edimburg Map Task . These two conditions allow to compare precisely feedback behaviors in different presence situation with the task remaining the same.
