Edinburgh MRI Modelled Speech Corpus
The Edinburgh magnetic resonance imaging (MRI) modelled speech corpus was created with funding from the Royal Society of Edinburgh (RSE), award no. 2082. Financial support was also provided by NHS Research Scotland (NRS), through the Edinburgh Clinical Research Facility. The Edinburgh MRI modelled speech corpus consists of dynamic midsagittal vocal-tract MRI recordings of English speech produced by model talker Prof. Janet Beck. MRI recordings were made at the Edinburgh Imaging Facility, Royal Infirmary Edinburgh (EIF RIE), using a 3 Tesla Siemens Prisma MRI scanner. Speech audio was recorded inside the MRI scanner using an OptoAcoustics FOMRI III dual-channel, fibre-optic microphone system with post-hoc noise cancelling. More information about MRI recordings can be found here. It should be noted that all speech recordings were made while the speaker was lying down and this will have an impact on tongue posture during speech. Additionally, teeth (i.e. the upper and lower incisors) are not visible in the MRI recordings of the vocal tract.
