Effects of Binaural Audio on English Vocabulary Learning

The English Picture Dictionary is a dictionary of stock pictures that represent meanings of English words. Following this, our aim was to create an audio repository of stock sounds that similarly represent meanings of English words. To effectively express the meaning of various English words through sound, we used binaural recording technology. For example, when recording the word "fetch," it was represented as a sound movement by moving a dummy microphone head from side to side, while pronouncing the word. This paper reports the results of a comparison between the effects of binaural and monaural audio on the learning of English vocabulary.
