Enrich the IPA-phoneme correspondence list. For English, eSpeak recognizes 96 phonemes (dictsource/dict_phonemes). Currently, only 55 are mapped using lexconvert and there may have been mistakes in interpreting lexconvert's conversion scheme. Additional correspondences should improve pronunciation.
Contribute to the underlying libraries. eSpeak, meSpeak.js, or the most current Emscripten'd variation to improve performance/size. meSpeak.js is currently over two megabytes.

It was odd that this tool did not exist; the underlying components were free (as in beer and freedom) and readily available for years (eSpeak was Emscripten'd in 2011: speak.js) alongside clear demand (e.g., in 2013, r/linguistics and Linguistics Stack Exchange).
There was a bookmarket for AT&T's Natural Voices demo, but the endpoint appears to be no longer available.
eSpeak, unfortunately, does not parse IPA phonetic notation directly, requiring the conversion assisted by lexconvert. Although the Emscripten'd version of eSpeak is somewhat large, two megabytes has become less noticeable as page sizes have increased over time. As a side effect, with no server-side processing and no automatic processing, privacy and security considerations were simplified (with the assumption that meSpeak.js is trustworthy).
