Document Type and Number:

WIPO Patent Application WO/2023/286139

Kind Code:

A1

Abstract:

This learning method comprises each of the following steps. In a first encryption step, a first acoustic feature amount extracted from confidential audio data is encrypted. In a first learning step, an acoustic model is trained on the basis of a second acoustic feature amount extracted from non-confidential audio data and a first acoustic model is generated. In a second encryption step, the first acoustic model generated in a non-confidential audio learning step is encrypted. In a second learning step, using the first acoustic model encrypted in the second encryption step as the base model, the encrypted first acoustic model is retrained on the basis of the encrypted first acoustic feature amount.
