Abstract
A method that includes: generating an utterance-specific scoring model for each one of a plurality of obtained speech utterances, each scoring model usable to estimate a level of speech naturalness for a respective one of the obtained speech utterances; presenting a plurality of human-testers with some of the obtained speech utterances; receiving, for each presented speech utterance, a plurality of human tester generated speech utterances being at least one human repetition of the presented speech utterance; updating the scoring model for each presented speech utterance, based on respective human-tester generated speech utterances; and obtaining a speech naturalness score for each presented speech utterance by respectively applying the updated utterance-specific scoring model to each presented speech utterance.
