... Similarity metrics for aligning children's articulation data
1. Background
This paper concerns the implementation and
testing of similarity metrics for the alignment of

of using this technique for the child-language
application, a task for whi...

indicating that characters are less noisy than
words, and are therefore more suitable for use in
align.
7. Conclusions
This paper has proposed a method for aligning

Aligning sentences is just a first step toward
constructing a probabilistic dictionary (Table 3)
