Classification: CPC G | IPC G

Claim 7:
8. A signal processing method, comprising:
receiving specific acoustic data of a mixed sound, wherein
the mixed sound includes a target sound of a target sound source and a non-target sound of a non-target sound source, and
the target sound source is different from the non-target sound source;

executing sound source separation to separate the specific acoustic data into first acoustic data of the target sound source and second acoustic data of the non-target sound source;
receiving a voice quality converter parameter, wherein
the voice quality converter parameter is trained based on a discriminator parameter, a speaker ID of the target sound source, and first training data of a sound of an input sound source,
the discriminator parameter is trained based on the first training data of the sound of the input sound source, second training data of the target sound of the target sound source, and third training data of a sound of a sound source different from the input sound source and the target sound source,
the target sound source is different from the input sound source,
the discriminator parameter discriminates the target sound source of the first acoustic data,
the first training data is based on the specific acoustic data of the mixed sound, and
the second acoustic data is different from parallel data and clean data;

executing voice quality conversion on the first acoustic data of the target sound to obtain third acoustic data, wherein
the conversion of the first acoustic data is based on the voice quality converter parameter, and
the first acoustic data is different from the parallel data and the clean data; and

synthesizing the third acoustic data and the second acoustic data of the non-target sound.
