Comparing dialect and accented pronunciations on the basis of transcriptions and articulography: Martijn Wieling, PhD

In the first part of the presentation, I will introduce the Pointwise-Mutual-Information-based Levenshtein distance which is able to determine sensitive pronunciation distances and sound segment distances on the basis of transcribed speech (Wieling et al., 2012). I will then apply the PMI-based Levenshtein distance to transcriptions of accented English speech obtained from the Speech Accent Archive
(http://accent.gmu.edu) and validate the method by comparing the computational distances to perceptual judgments of hundreds of native American English speakers (Wieling et al., in press).

In the second part of the presentation, I will illustrate how articulography (i.e. measuring the movement of tongue and lips during speech) is useful for comparing pronunciations. To illustrate the method, I will show significant movement differences between native and non-native speakers of English speakers, as well as Dutch dialect speakers.
