Abstract
A technology for assessing foreign language pronunciation of a non-native learner is provided. The foreign language pronunciation assessment technology includes training an end-to-end speech recognizer with native speaker data, tuning the trained end-to-end speech recognizer with non-native speaker data, training a scoring module on the basis of the finely tuned end-to-end speech recognizer, and calculating, by the trained scoring module, a prediction score for non-native speaker speech input when the non-native speaker speech is input to the tuned end-to-end speech recognizer.
