Free Public AI Model for Handwritten Text Recognition with Transkribus

Spanish Redonda (Round Script) 16th-17th Century

This general model is based on different Spanish printed books in Redonda (Round) typeface and published between 16th-17th Century. Digitized images used to create the model come from different online repositories, mainly Biblioteca Digital Hispánica, the official repository of Biblioteca Nacional de España (BNE).

Around 20 pages per book were taken and several accomplished scholars participated in the transcription phase. The dataset of the current version corresponds to 21 documents, 15˙897 lines and 119˙856 words.
