Voice correction apparatus and voice correction method

A voice correction apparatus comprising:

• a memory;
• and
• a processor coupled to the memory, the processor being configured to:
• execute an emphasis processing configured to
• obtain first voice information which is voice information recorded when noise is generated and on which noise suppression processing is performed to yield a noise suppressed first voice information and second voice information indicating voice information recorded in an environment in which no noise is generated, and
• generate emphasized information by emphasizing a component of a band, corresponding to a band having a low signal noise ratio (SNR) of the noise suppressed first voice information, among bands of the second voice information;
• execute a learning processing configured to perform machine learning on a model based on the noise suppressed first voice information and the emphasized information;
• and
• execute a correction processing configured to generate corrected voice information by correcting third voice information on which noise suppression processing is performed, based on the model machine-learned by the learning processing.
