# Use a Lattice File

You can record details of word hypotheses that were considered during recognition, not simply the best scoring hypothesis, in a lattice file. You can then search for occurrences of specific words in the lattice to aid recall. In addition, you can restrict the lattice to instances of particular words.

You can also restrict the lattice to a single example of each word in the window that you specify with the `LatWinSize` parameter. Alternatively, you can control the depth of the lattice by specifying that poorly scoring hypotheses must not be included. For more information on setting up and configuring lattice files for use in speech-to-text processing, see the IDOL Speech Server Reference.
