Audio signal conversion model learning apparatus, audio signal conversion apparatus, audio signal conversion model learning method and program

A voice signal conversion device comprising:

• acquiring a conversion target voice signal that is a voice signal corresponding to a conversion target;
• and
• converting the conversion target voice signal using a model of machine learning for converting the conversion target voice signal obtained by a voice signal conversion model learning device comprising:
• a processor;
• and a storage medium having computer program instructions stored thereon, wherein the computer program instruction, when executed by the processor, perform processing of:
• executing generation processing of generating a conversion destination voice signal on the basis of an input voice signal that is a voice signal of an input voice, conversion source attribute information that is information indicating an attribute of an input voice that is a voice represented by the input voice signal, and conversion destination attribute information indicating an attribute of a voice represented by the conversion destination voice signal that is a voice signal of a conversion destination of the input voice signal;
• and executing voice estimation processing of estimating whether or not a voice signal that is a processing target is a voice signal representing a voice sound actually uttered by a person on the basis of the conversation source attribute information and the conversation destination attribute information, wherein the conversion destination voice signal is input to the processing of executing of generation processing, the processing target is a voice signal input to the processing of execution of generation processing, and the processing of execution of generation processing and the processing of execution of voice estimation processing are learned on the basis of an estimation result of the voice estimation processing.

A voice signal conversation model learning method executed by a voice signal conversation model learning device comprising:

• a processor;
