A question about Lattice::LatticeWER( )

[liuchangliang]

  Hi:

 

         I use lattice-tool to compute the lattice WER. In the result, the
insertion error is always very high. 

In the source code of function Lattice::LatticeWER( ), there is a sentence:

         * NOTE: since we process nodes in topological order this

    * will allow chains of multiple insertions.

 

    I don't know what this sentence mean? Does that mean the insertion error
of the result is not reliable ?

 

Thanks

chliu
