Virtual Face-to-Face Pronunciations

Research suggests that language learners can perform better with added visual pronunciation instruction versus simply audio. For example, here's one fairly recent paper http://mambo.ucsc.edu/pdf/interspeech2008.pdf that we've found to motivate the specific ideas behind virtual face-to-face pronunciations. If you are deeply interested in this idea, we suggest taking a look at the citations in the end of the paper as they trace back several years of research in visual speech training and language.
