The International Phonetic Alphabet (revised to 2005)
There are two MRI viewing options for both charts: MRI 1 and MRI 2.
- MRI 1 was recorded in 2014 at Edinburgh Imaging Facility QMRI, with a frame rate of 7.5fps. Each file has been overdubbed with “clean” audio, recorded in a recording studio.
- MRI 2 was recorded in 2022-2023 at the Edinburgh Imaging Facility, RIE, with a frame rate of 6.25fps and a 70% increase in image resolution, compared to MRI 1. Audio for the MRI 2 files was recorded in the MRI machine using an optical microphone and post-hoc noise cancelling. We aim to replace the MRI 2 audio with clean audio in the near future.
