Application ID: 13402602

Base Claim:
1. A method for speech synthesis, comprising: determining data generated by text analysis as fuzzy heteronym data; performing a fuzzy heteronym prediction on the fuzzy heteronym data to output a plurality of candidate pronunciations of the fuzzy heteronym data and probabilities thereof; generating fuzzy context feature labels based on the plurality of candidate pronunciations of the fuzzy heteronym data and the probabilities thereof; determining model parameters for the fuzzy context feature labels based on an acoustic model with a fuzzy decision tree; generating speech parameters for the model parameters, using a device selected from the group consisting of a computer and a logic circuit; and synthesizing the speech parameters as speech.

Claim 2:
2. The method according to claim 1 , wherein the step of generating fuzzy context feature labels further comprises: determining a degree to which context labels of candidate pronunciations of the fuzzy heteronym data fall into category based on the probabilities; and transforming the degree by scaling to generate the fuzzy context feature labels, wherein the fuzzy context feature labels are joint representation of context labels of the candidate pronunciations.
