--Adapted from [[Module:es-pronunc]] by [[User:Benwing2]]

--TODO
--This code is adapted from [[Module:pronunc]], which can output multiple dialectal pronounciations from a single spelling. This module will
--return a single pronunciation per spelling in all cases, so there are parts of the code which can be simplified.
