Abstract:
A computer-based method of automatically generating, from a first speech recognizer, a second speech recognizer, wherein the first speech recognizer includes a set of states and a set of probability density functions assembling output probabilities for an observation of a speech frame in the states, the method comprising the steps of:generating, from the set of states of the first speech recognizer, a set of states of the second speech recognizer by selecting a subset of states of the first speech recognizer being distinctive of a particular application; and generating, from the set of probability density functions of the first speech recognizer, a set of probability density functions of the second speech recognizer by selecting a subset of probability density functions of the first speech recognizer being distinctive of the particular application, such that the second speech recognizer is at least one of tailored to the particular application and requires reduced resources compared to the first speech recognizer.
