Automatic pronunciation evaluation of language learners' utterances generated through shadowing
نویسندگان
چکیده
In foreign language learning, shadowing has been used as a method for improving speaking and listening ability. In this method, learners are required to repeat a presented native utterance as closely and quickly as possible. Since learners have to follow the speaking rate of the presented utterance, their pronunciation often becomes very inarticulate and unintelligible. These features of shadowing make it very difficult to build a reliable scoring system for shadowing productions. In this paper, two techniques are proposed and investigated for automatic scoring of shadowing productions. Experiments show that good correlations are found between automatic scores and TOEIC overall proficiency scores.

متن کاملAutomatic Scoring of Shadowing Speech Based on DNN Posteriors and Their DTW
Shadowing has become a well-known method to improve learners’ overall proficiency. Our previous studies realized automatic scoring of shadowing speech using HMM phoneme posteriors, called GOP (Goodness of Pronunciation) and learners’ TOEIC scores were predicted adequately. In this study, we enhance our studies from multiple angles: 1) a much larger amount of shadowing speech is collected, 2) ma...

Italian speakers tend to stress the second component of German morphologically complex words such as compounds and prefix verbs even if the first component is lexically stressed. To improve their prosodic phrasing an automatic pronunciation teaching method was developed based on auditory feedback of prosodically corrected utterances in the learners’ own voices. Basically, the method copies cont...
