1. A method comprising: detecting, by at least one processor, occurrence of an out-of-vocabulary word in a text sample; detecting a likelihood that the out-of-vocabulary word will be mispronounced using a primary text-to-speech synthesizer associated with a primary language; receiving feedback from a source other than the primary text-to-speech synthesizer, the feedback indicating a conversion in accordance with a secondary language of the out-of-vocabulary word into a corresponding audio output; storing the feedback in a repository: generating, based on the feedback and by a secondary text-to-speech synthesizer associated with the secondary language, a first audio pronunciation of the out-of-vocabulary word pronounced in accordance with a native secondary language speaking person speaking the secondary language; and generating, in accordance with a native primary language speaking person speaking the primary language, a second audio pronunciation of the out of vocabulary word.

The method as in claim 1 , wherein detecting the likelihood that the out-of-vocabulary word will be mispronounced using the primary text-to-speech synthesizer includes: implementing the primary text-to-speech synthesizer in a first language, the out-of-vocabulary word being absent from a lexicon lookup of the first language.
