lattice-tool and noise probability

Hello,

When rescoring lattices using lattice-tool, is there a possibility (or
a workaround) to assign a LM probability to noise words? The noise
words should still be skipped when calculating n-gram probabilities
for other words.

I understand that currently, noise words get a LM probability of
log-zero, which may make them too probable to be inserted in place of
other candidates.

Regards,
Tanel
