Abstract
Previous research has shown that prosodic speech features distinctively reflect one’s accuracy and subjective confidence on an answer. These features can be used to enhance the effectiveness of adaptive learning systems and thus help provide a more personalised learning experience. The current study investigated how prosodic features of sentences (speaking speed, intensity and pitch) reflect accuracy and subjective confidence in individuals learning a language. We also assessed the strength of these relationships in native language utterances compared to second language utterances. In this experiment, native Dutch speakers studied and verbally retrieved short subject-verb sentences in Dutch and Italian in a counterbalanced order. Our results indicate that accuracy in an answer was best reflected by a higher mean pitch and lower mean intensity, whereas confidence was best reflected by a higher speaking speed and a larger pitch fall at the end of the sentence. Additionally, prosodic features were more informative of one’s learning performance in the native language than in the second language. Our findings indicate that prosodic information, especially in the native language, could be a valuable tool to improve adaptive learning systems’ estimations of a learner’s knowledge and feeling of knowing. We recommend that future researchers focus on applying these findings to real-world language learning contexts. Keywords: PSFs, accuracy, confidence, language, ALSs
