Some of the results of an investigation of the imitation of auditory speech stimuli, and the identification of spontaneous and imitative speech are presented. In the investigation, listeners were found to have difficulty identifying non-spontaneous stimuli, and judgements of imitative quality were not found to correlate with naive spontaneous~non-spontaneous judgements. This paper presents the results of a further set of quality-judgements and discusses them in relationship to the productional characteristics of the imitations and previous parts of investigation.
