1. A computer-implemented method of indexing a speech lattice for search of audio corresponding to the speech lattice, the method comprising:
- identifying at least two speech recognition hypotheses for a word which have time ranges satisfying a criteria; and
merging the at least two speech recognition hypotheses to generate a merged speech recognition hypothesis for the word.

Abstract
A computer-implemented method of indexing a speech lattice for search of audio corresponding to the speech lattice is provided. The method includes identifying at least two speech recognition hypotheses for a word which have time ranges satisfying a criteria. The method further includes merging the at least two speech recognition hypotheses to generate a merged speech recognition hypothesis for the word.

12. A computer-implemented method of searching audio, the method comprising:
-
receiving a search query;
searching an index corresponding to the audio for entries associated with the search query;
for each of a plurality of speech signals, retrieving from the entry an identifier for the speech signal, time range information for a word hypothesis associated with the entry, and a probability of the word hypothesis appearing at the time range given the speech signal;
using the probabilities to rank the speech signals relative to each other to form ranked speech signals; and
returning search results based on the ranked speech signals. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
