Abstract:
An apparatus for creating a set of expanded speech models comprising:an input for receiving a signal representative of enrollment data; a processing unit coupled to said input, said processing unit being operative for: a) processing said enrollment data to generate a set of simple speech models trained on a basis of said enrollment data, each simple speech model in said set of simple speech models comprising a plurality of states linked by transitions; b) generating on a basis of the set of simple speech models a set of expanded speech models, each expanded speech model in said set of expanded speech models comprising a plurality of groups of states, the groups of states being linked to one another by a plurality of inter=group transitions, states in a given group of states originating from a state in a given simple speech model of said set of simple speech models; c) processing the set of expanded speech models on the basis of the enrollment data to condition at least one of the plurality inter-group transitions on the basis of the enrollment data; an output for releasing a signal conveying the set of expanded speech models in a format suitable for use by a speech processing device.
