Hi,
No, because this is usually a bad idea. Kneser-Ney smoothing
conditions lower-order probabilities on having backed off, so a 12-gram
model used as a 5-gram will provide you with a properly normalized
model, but it's not the distribution you want.
For more on this rant and how to fix it, see my paper:
