I am building a web application that allows users to transcribe, word by word, Early Modern English manuscripts.
I want to tell users when a word they transcribed may be a new spelling variant of that word.
For doing that I need to interrogate a database via an API call. The database would be a comprehensive list of spelling variations of all words in Early Modern English.
I've tried the Oxford English Dictionary one but it seems a bit unreliable (sometimes it takes 40+ sec to return just a few records).
Has anyone done this before? Does anyone know of any API that could help?
