Method and apparatus for training speech synthesis model, device, storage medium and program product

An apparatus for training a speech synthesis model, comprising:

• a memory storing a plurality of computer-executable instructions;
• and
• a processor configured to execute the plurality of computer-executable instructions, wherein upon execution of the plurality of computer-executable instructions, the processor is configured to:
• obtain a text sample and a standard speech corresponding to the text sample;
• perform speech bit stream prediction on the text sample by using the speech synthesis model, to obtain a speech bit stream corresponding to the text sample;
• decode the speech bit stream by using the speech synthesis model, to obtain a synthesized speech corresponding to the text sample;
• and
• update a model parameter of the speech synthesis model based on a difference between the synthesized speech and the standard speech, the speech synthesis model being configured to output, based on inputted target text, a synthesized speech of the target text.

A non-transitory computer-readable storage medium storing a plurality of computer-executable instructions, wherein when executed by a processor, the plurality of computer-executable instructions cause the processor to:

• obtain a text sample and a standard speech corresponding to the text sample;
• perform speech bit stream prediction on the text sample by using the speech synthesis model, to obtain a speech bit stream corresponding to the text sample;
• decode the speech bit stream by using the speech synthesis model, to obtain a synthesized speech corresponding to the text sample;
• and
• update a model parameter of the speech synthesis model based on a difference between the synthesized speech and the standard speech, the speech synthesis model being configured to output, based on inputted target text, a synthesized speech of the target text.
