Another term paper using project material written by Ingrid Lindahl (2001) dealt with feedback and its relationship with dialogue move/speech act type. In the goal related travel bureau dialogues studied in the project it is seen for example, that the most common feedback type is constituted by variants of mm with level tone and that they occur most commonly with the speech acts Explain and Clarify (for dialogue move classification, see Carletta et al. 1997). Mm with a falling-rising accent on the other hand was associated with an other kind of dialogue move, i.e. Instruct.
