1. INTRODUCTION
</SectionTitle>
    <Paragraph position="0"> Many laboratories have now used the so-called 'Wizard of Oz' (WOZ) technique for eliciting spontaneous spoken human-machine dialogue in order (i) to study the resulting speech and (ii) to evaluate the necessary speech technology and natural language processing systems \[1\]. The technique is particularly valuable because it enables user behaviour to be studied under conditions which are not constrained by the limitations of current technological (or theoretical) capabilities.</Paragraph>
    <Paragraph position="1"> However, many such exercises involve 'volunteer' users whose behaviour is prescribed by a pre-prepared scenario \[6\] thereby removing one potentially crucial aspect of human-machine interaction, namely any behavioural events which are unique to genuine (i.e. motivated) and un-preprepared transactions \[4\].</Paragraph>
    <Paragraph position="2"> This paper presents $RU's first experiences collecting unscripted speech data using the WOZ technique by the provision of a genuine voice-based telephone enquiry service to personnel on the RSRE site.</Paragraph>
