We recorded non-native English productions of 55 speakers; a subset of these productions was assessed by 60 native English speakers as for their quality w. r. t. intelligibility, rhythm, etc. Applying multiple linear regression on a large prosodic feature vector – modelling approaches known from the literature as well as generic prosody – we can automatically predict the listener's assessments with correlations of up to .85. We discuss most important features and limitations of this approach.

Index Terms: non-native prosody, rhythm, intelligibility, foreign accent, linear correlation
