FEATURES OF LATTICES


  • Finite state networks - nodes and arcs

  • Arc represents a word instance occurring between two nodes


  • Start and end node
  • Pronunciation variant
  • Acoustic score
  • LM score

  • Node represents a word end hypothesis


  • Word end identity
  • Time of word end
  • Following nodes
  • Previous nodes

  • Generic lattice generation information


  • LM scale factor
  • Word insertion penalty
