Abstract:
1. A method of adaptation of a user-specific acoustic model, comprising: receiving, by a processor, initial speech input data in form of a plurality of words from a user, the initial speech input data including less speech data than is necessary to adapt a user-specific acoustic model to identify the user based upon any subsequently received speech input data; simulating specific speech characteristics of the user based at least in part upon the initial speech input data; generating additional speech data including one or more simulated words for the user based at least in part upon the initial speech input data and the specific speech characteristics of the user; combining the initial speech input data from the user and the generated additional speech data; adapting the user-specific acoustic model for speech recognition of the speaker based at least in part upon the combined initial speech input data and the generated additional speech data; and refining the user-specific adapted acoustic model until the adapted user-specific acoustic model is sufficiently tuned to the speech of the user to adequately identify the user based upon subsequently received speech input data from the user.
