Claim 18:
19. A system for providing a text output for automatically recognized speech, comprising:
a phrase generating unit to receive a lattice output of an Automatic Speech Recognition (ASR) unit for an input audio file, identify non-overlapping time interval spans in the lattice output corresponding to speech utterances, with each span having a starting point and an ending point, generate a masked version of the lattice output for each span to create a masked lattice for each span; and find a list of N-best phrase hypotheses for each span on the received ASR lattice output for the input audio file, where N is a positive integer; and
an indexing unit receiving an output of the phrase generating unit and generate an index for a transcript of the input audio file having phrase alternatives.
