Speaking through a noisy channel - experiments on inducing clarification behaviour in human-human dialogue
David Schlangen, Raquel Fernández · 2007
We report results of an experiment on inducing communication problems in human-human dialogue.We set up a voice-only cooperative task where we manipulated one channel by replacing (in real-time, at random points) all signal with noise.Altogether around 10% of the speaker's signal was thus removed.We found an increase in clarification requests of a form that has previously been hypothesised to be used mainly for clarifying acoustic problems.We also found a correlation between the percentage of an utterance being manipulated and the use of devices for pointing out error locations.From our findings, we derive a gold-standard policy for clarification behaviour.
