Comparing these results with the results in Tables 1 and 2, we find that while overall the performance of contextual non-combined feature sets shows a small performance increase over most non-contextual combined or non-combined feature sets, there is again a slight decrease in performance across the best results in each table.
there is no significant difference between these best results (alltext+glob-ident vs. all-text+speech+ident vs. alltext+ident).
