1. A method comprising:
- providing a set of subword unit models;
for each of two acoustic events, a first acoustic event occurring in a first acoustic signal and a second acoustic event occurring in a second acoustic signal, and for each of a series of times in each of the events, computing a probability associated with each model of the set of subword unit models; and
computing a quantity characterizing a comparison of the two acoustic events using the computed probabilities.

Abstract
An approach to comparing events in word spotting, such as comparing putative and reference instances of a keyword, makes use of a set of models of subword units. For each of two acoustic events and for each of a series of times in each of the events, a probability associated with each of the models of the set of subword units is computed. Then, a quantity characterizing a comparison of the two acoustic events, one occurring in each of the two acoustic signals, is computed using the computed probabilities associated with each of the models.

14. Computer-readable media encoded with computer readable software comprising instructions for causing a processing system to:
-
retrieve models for a set of subword units; for each of two acoustic events and for each of a series of times in each of the events, compute a probability associated with each of the models of the set of subword units; and compute a quantity characterizing a comparison of the two acoustic events, one occurring in each of the two acoustic signals, using the computed probabilities associated with each of the models.
