I'm working on a website(*) that provides word pronunciation guides for a general audience that cannot be expected to know IPA symbols.
It would be enormously helpful to have a tool where I could paste or highlight ē-thē-ˈō-pē-ə and get back ee-thee-O-pee-uh , for example. (A Chrome extension would be most helpful, or a website, but any tool can be adapted.)
I found a similar question asked in 2013 but 4 years is a long time on the web; in 2013 the best answer was "learn the IPA" which is not a useful answer for my purposes.
There are a great many books and web sites out there where pronunciation guides are supplied which give common words as examples of a given phoneme, and then use the 26 letters of the standard English alphabet to provide phonetic pronunciations; that's what I want to emulate. I'm not trying to bootstrap English for learners, I'm trying to help people who are already fluent in English learn the pronunciation of unfamiliar vocabulary. To stress the point, "Learn the IPA" is inappropriate for my target user audience.
An example of the type of phonetic representation I want to provide is at this Biblical name glossary which gives a simple spelling of the sound of each name.
(*) The OEDILF -- an audacious attempt to provide a limerick for every word in the English language. New contributors very welcome.
