Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for decoding parameters for Viterbi search are disclosed. In one aspect, a method includes the actions of receiving lattice data that defines a plurality of lattices. The actions include for each defined lattice determining a particular path that traverses the lattice; determining a node cost of a path from the start node to the frame node; determining a beam size for each frame; determining a beam cost width for each frame; determining a maximum beam size from the beam sizes determined for frames; and determining a maximum beam cost width from the beam cost widths determine for the frames. The actions include selecting a particular beam size and a particular beam cost width. The actions include determining paths for additional lattices using the pruning parameters of the particular beam size and the particular beam cost width.
