Segmenting Words from Natural Speech: Subsegmental Variation in Segmental Cues
Rytting, C. Anton; Brew, Chris; Fosler-Lussier, Eric
Journal of Child Language, v37 n3 spec iss p513-543 Jun 2010
Most computational models of word segmentation are trained and tested on transcripts of speech, rather than the speech itself, and assume that speech is converted into a sequence of symbols prior to word segmentation. We present a way of representing speech corpora that avoids this assumption, and preserves acoustic variation present in speech. We use this new representation to re-evaluate a key computational model of word segmentation. One finding is that high levels of phonetic variability degrade the model's performance. While robustness to phonetic variability may be intrinsically valuable, this finding needs to be complemented by parallel studies of the actual abilities of children to segment phonetically variable speech.
