c# - How to preset a score for a specific type of insertion/deletion in Levenshtein?

Question

I'm currently looking at determining the Levenshtein distance (coded in C#) between two words based on a series of pre-determined phonological correspondences. The difference between two characters is based on a 0-1 scale. This works quite well for substitutions.

The problem arises with insertions and deletions. Under normal circumstances, adding or deleting a character would give a score of 1, but some characters in this specific language (e.g. the 'h') can be added or deleted without causing any problems, and therefore they should get a lower score (of, say, 0.1).

Is it possible to pre-determine the score for insertions/deletions independently from substitutions (because substitution of this 'h' would still require a high score), and to set a score for a specific character's insertion/deletion? Currently, the algorithm seems to override any set value and to be determined to add a score of "1" to each insertion/deletion of 'h'.
