Abstract:
1. A method, comprising: receiving, by a computing device, speech data corresponding to one or more spoken utterances of a particular speaker; recognizing textual elements of a first input text corresponding to the speech data; determining confidence levels associated with the recognized textual elements; adapting speech-synthesis parameters of one or more decision trees based on the speech data, recognized textual elements, and associated confidence levels, wherein each adapted decision tree is configured to map individual elements of a text to individual of the speech-synthesis parameters, and wherein adapting the speech-synthesis parameters of one or more decision trees comprises: receiving a second input text; mapping the second input text to a set of speech-synthesis parameters using the one or more adapted decision trees; and generating a synthesized spoken utterance corresponding to the second input text using the set of speech-synthesis parameters, wherein at least some of the speech-synthesis parameters in the set of speech-synthesis parameters are configured to simulate the particular speaker.
