This study tested the application of adapted HTK for
automatic alignment of speech corpus of Asian speakers’
English. The HTK tool with TIMIT has problems in aligning
non-native speakers’ English. New sets of phoneme sequences
for each word were listed to test if an adapted alignment
module could accurately analyze pronunciation of Japanese
speakers’ English. The new sets of phoneme sequences
produced better alignment of Japanese accented English and
showed that the L2 incorporated new alignment module could
perform more accurate automatic alignment of L2 English data.
The same methods should be able to be applied to other
language data.
