Queen Margaret University ultrasound, audio and video multichannel recording facility (2008-2016)

Abstract

This working paper describes some of the technical characteristics of the QMU speech recording facility, used to record high speed ultrasound, video, audio and other channels. It has been used by a number of projects at Queen Margaret University, in the Clinical Audiology, Speech and Language Research Centre since 2008, and some technical information has been made available in a range of publications, manuals and student reports. Here we collate in one place the background information relevant to issues of spatial resolution, time resolution, temporal synchronisation, edge detection and confidence, and comment on their general relevance for ultrasound-based speech research at QMU and in other laboratories
