Abstract:
1. A method for recognizing speech in an output domain, the method comprising: at a device comprising one or more processors and memory: establishing a global speech recognition model based on an initial set of training data; receiving a plurality of input speech segments to be recognized in the output domain; and for each of the plurality of input speech segments: identifying in the global speech recognition model a respective set of focused training data relevant to the input speech segment; generating a respective focused speech recognition model based on the respective set of focused training data; and providing the respective focused speech recognition model to a recognition device for recognizing the input speech segment in the output domain; wherein establishing the global speech recognition model based on the initial set of training data further comprises: generating the initial set of training data from a plurality of training speech samples, the initial set of training data including an initial set of speech segments and an initial set of speech templates; and deriving a global latent space from the initial set of speech segments and the initial set of speech templates.
