Early Preparation of Experimentally Elicited Minimal Responses

In both human-human and human-machine conversation, an important task for the participants is to identify the moment the other participant finishes speaking, giving them the possibility of taking over the turn in talk. In an RT experiment, consistent evidence was found for an intermediate stage in the planning and articulation of elicited minimal responses in the shape of early larynx and glottal movements in laryngograph recordings. Using a simple Response Time model, it is estimated that this intermediate stage occurs at approximately 2/3 of the integration-time needed for the articulation of a response. Impoverished intonation only stimuli were still adequate to elicit minimal responses, but a longer integration-time was required to initiate a response.
