Repetitions

• Other-repetition is a device involving the reproduction by a speaker of what another speaker has just said.
• Other-repetition has been identified as an important mechanism in face-to-face conversation through their discursive or communicative functions.
• Example:

AB: ils voulaient qu'on fasse un feu d'artifice en fait dans un voy- un foyer un foyer catho 
un foyer de bonnes soeurs

CM: un feu d'artifice

AB: ah ouais

CM: dans un foyer de bonnes soeurs 

CM: @

Repetitions

• No system already existing
• Our solution is based only on lexical criteria
  • observable cues: time-aligned tokens converted to lemmas (if any).
• The system was used to propose a lexical characterization of OR: various statistics was estimated on the detected OR.
