Speech Prosody 2010
Chicago, IL, USA
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
