Text-to-speech synthesis system and method

A computer-implemented method, comprising:

• comparing synthetic speech data for an input text to recorded reference speech data corresponding to the input text;
• extracting a plurality of features with each indicative of at least one difference between the synthetic speech data and the recorded reference speech data based on, at least in part, comparing the synthetic speech data to the recorded reference speech data;
• generating a speech gap filling model based on, at least in part, the plurality of features extracted;
• predicting a best sequence of the plurality of features extracted to be added to an interim set of parameters for synthesis of a speech output;
• generating the speech output based on, at least in part, the speech gap filling model and the best sequence of the plurality of features added to the interim set of parameters.

A computer program product residing on a computer readable storage medium having a plurality of instructions stored thereon which, when executed across one or more processors, causes at least a portion of the one or more processors to perform operations comprising:

• comparing synthetic speech data for an input text to recorded reference speech data corresponding to the input text;
• extracting a plurality of features with each indicative of at least one difference between the synthetic speech data and the recorded reference speech data based on, at least in part, comparing the synthetic speech data to the recorded reference speech data;
• generating a speech gap filling model based on, at least in part, the plurality of features extracted;
• predicting a best sequence of the plurality of features extracted to be added to an interim set of parameters for synthesis of a speech output;
• generating the speech output based on, at least in part, the speech gap filling model and the best sequence of the plurality of features added to the interim set of parameters.
