Kudos on a useful concept. Some feedback: Alternate pronunciations seems to go a bit wonky. For example it pronounces Ribosome [1] (/ˈraɪbəˌsoʊm, -boʊ-/) as ri-bo-some-bo :). Overall quite a nifty tool as many wikipedia pages do not have native pronunciation recordings. Could also see it helping casual learners of IPA.
