The speakers communicated via headsets.Ī laboratory set-up like this is hardly the most natural environment for communication, but it turned out to be necessary in order to obtain recordings of sufficiently good quality for subsequent acoustic analysis: Seated in the same room, across from each other with eye-contact, speaker A could invariably be heard over speaker B's microphone, and vice-versa whereas we got clean acoustic signals when the speakers were separated, with no appreciable difference in quality from the studio proper and the ad hoc studio established in the control room. They were seated in separate locations, one the department's recording studio, the other a recording facility established for the purpose in the main control room, with curtains of very heavy material surrounding the speaker. The exercise involved the cooperation of two participants. They are replicas of the Human Communication Research Centre's Map Tasks (cf. The dialogues were recorded in the summer of 2004. Instructions as they were read to the speakers. This house is an almost exact copy of Terken's (1984) edifice. The speaker then guided the experimenter through four different routes in a virtual city map, inspired by Swerts (1994).įinally, the speaker – who had a model – told the experimenter how to assemble a house from its individual pieces. It was specifically intended to reveal whether or not speakers look ahead and signal prosodically an upcoming utterance boundary prior to its actual occurrence. ![]() It is an elaboration of Swerts and Collier's (1992) network. The speaker first described a network consisting of various geometrical shapes in various colours. The analog recordings were digitized later, at a sampling frequency of 48kHz, and transferred to cd-roms. Speakers were recorded with professional equipment (Sennheiser Microphone ME64, Revox A700, Agfa PEM368 tape). In other words, the monologues were recorded in one-way communication with an unseen partner who offered no feedback, neither in the form of questions nor confirmation. Once the speaker had been instructed in the specific task, (s)he could no longer address the experimenter with questions or comments. The speaker was seated alone in the professional recording studio in the former Department of General and Applied Linguistics (now part of the Department of Scandinavian Studies and Linguistics) and could communicate with the experimenter only via microphone and headphone. They represent various types of instructions. On the other hand the speech is non-scripted. This is to facilitate comparison across speakers and ensure sufficiently uniform materials for subsequent analyses. Apart from the word lists, the corpus represents an approximation to speech in a natural setting: On the one hand the material for elicitation is controlled in the sense that the speakers are given specific tasks to talk about. The corpus consists of monologues and dialogues with word lists. Nevertheless, the corpus may serve as a basis for any number of linguistic and/or speech technological investigations.Ĭarlsbergfondet financed the project. There are therefore a considerable number of discourse variables that have not been taken into account in the choice of elicitation material. That is, the primary goal is neither syntactic, pragmatic, socio-linguistic, psychological, nor whichever other aspect of spoken language one might wish to investigate. The corpus is intended for acoustic and perceptual phonetic investigations.
