I am the developer of the Namsel OCR project (https://www.namsel.com/) and can speak to a few different Tibetan OCR implementations. First, you may want look at tbrc.org and particularly their e-text section. We've OCR'd the entire Tibetan Tengyur and Kangyur as well as hundreds of thousands of additional pages of Tibetan literature and made it available for search there.
As already mentioned in this thread, there is also the Yakpo OCR project (http://www.dharmabook.ru/ocr/). The Google Drive/Google Docs and Google Books projects have recently added support for Tibetan OCR, although from what I understand it is still a work in progress. As far as I can tell, the Google Doc OCR service isn't presently meant for building large collections of OCR text, but can handle documents of a few pages. Otherwise, you can try searching this email list for previous discussions on training Tesseract. For example, Tenzin Dendup has spent time attempting to train Tesseract on Tibetan/Dzongkha: https://groups.google.com/d/msg/tesseract-ocr/ONkAD2kuxUQ/EQsepM67D94J On Tuesday, November 24, 2015 at 11:11:52 PM UTC-8, Yizhen Hai wrote: > > I am working on a volunteer project to digitize the Sutra and all related > materials, most of them in Tibetan.
