IF I ever get around to constructing a conlang I'll probably algorithmically generate its vocabulary from Wiktionary entries. Wiktionary includes pronunciations in IPA format (and audio files), spellings, and translations between hundreds of languages.
(I'd build up an inventory of easily distinguished phonemes, match words of like meaning, and then use machine learning to synthesize a vocabulary out of like-sounding synonyms.)
While some prominent conlangs have attempted something like this in the past, they were forced to cherry-pick and use subjective judgements. Today modern technology enables us to do it with a thoroughness and at a scale previously unfeasible. Lojban spliced together vocabulary from 6 languages; with machine learning and Wiktionary, we can algorithmically splice together hundreds.
I'd find it interesting to see what kind of language you would come up with if you algorithmically synthesized your vocabulary and pronunciations from Wiktionary's database of worldwide languages and developed your syntax from Galactical Dependencies' most representative grammars. Would it resemble Esperanto or Lojban, or would it look like something else entirely?
