The models were trained upon roughly 2500 pages (ca. 400k words) of handwritten transcriptions from the School of Scottish Studies Archives (https://www.ed.ac.uk/information-services/library-museum-gallery/cultural-heritage-collections/school-scottish-studies-archives). The transcriptions are from recordings of hero tales and international tales in Scottish Gaelic, made between 1949 and 1979. They were gathered from tradition bearers living in the Scottish Highlands and Islands. The majority of the transcriptions are from one hand (~80%) with the remainder split across approximately 10 hands. Thus, the generalisability of the models is limited at present. We hope to diversify the training data in the future by adding further hands.
