Has anyone tackled training for the IPA since this initial query? I'm considering using Tesseract to OCR the first edition of the Oxford English Dictionary (as input to a crowdsourced proofing process) and trying to decide whether it's worth training it to recognized the pronunciations. I'm also not sure how close the OED version is since the original IPA was developed in 1886 and the first volume of the first edition of the OED was published in 1888, so perhaps they used a homegrown variant.
Here's the alphabet: https://archive.org/stream/ANewEnglishDictionaryOnHistoricalPrinciples.10VolumesWithSupplement/01.NEDHP.AB.Oxford.Murray.1888.#page/n22/mode/1up here's an example page with it in use: https://archive.org/stream/ANewEnglishDictionaryOnHistoricalPrinciples.10VolumesWithSupplement/01.NEDHP.AB.Oxford.Murray.1888.#page/n326/mode/1up Any opinions on whether it's worth training for the phonetic alphabet or is it going to just be too difficult to recognize even with specific training?
