Lattice Spoken Term Detection toolkit (LatticeSTD)
Toolkit for experiments with lattice based spoken term detection. It allows you to define set of terms and search them in lattices.
* Searches for defined sequence of links in lattice and outputs label assign to this sequence.
* Calculates confidence of found sequence (posterior probability)
* Filter overlapped detection
* Allows handle substitutions/deletion/insertion (useful for phone lattices)
