This paper investigates the reliability of phonetic boundaries
obtained through automatic segmentation of non-native speech
for automatic prosodic feedback for foreign language learning.
Indeed, prosodic feedback requires checking the fundamental
frequency and the duration of phonetic segments of the learner
utterances with respect to some reference patterns.
Segmentation evaluations carried out on non-native speech
data show that the automatic segmentation process takes
benefit from the introduction of non-native pronunciation
variants, and that several phonetic boundaries obtained
through automatic segmentation seems to be reliable enough
for providing relevant prosodic feedback. This concerns for
example boundaries between obstruent sounds, such as
plosives and fricatives, and vowel sounds.
Index Terms. Language learning, automatic phonetic segmentation, non-native speech.
