... terms to the phonetic transcription of the second output in the n-best list, as compared to the other outputs. One obvious problem with this method is that it ignores the relative ordering of the n-best ... transliterations. In the case of DIRECTL+, the transliterations help through the n-gram features rather than the score features; this is probably because the cr...
