Voice processing method, voice processing apparatus, and non-transitory computer-readable storage medium for storing voice processing computer program

A voice processing apparatus for estimating an impression of speech, the apparatus comprising:

• a memory;
• and
• a processor coupled to the memory and configured to
• execute an acquisition process that includes acquiring voice signals,
• execute a feature acquisition process that includes acquiring acoustic features regarding the voice signals from the voice signals,
• execute a voice-parameter acquisition process that includes acquiring a voice parameter regarding a frame of the voice signals,
• execute a relative-value determination process that includes determining a relative value between the determined voice parameter and a statistical value of the voice parameter,
• execute a weight assignment process that includes assigning a weight to the frame of the voice signals in accordance with the relative value, and
• execute a distribution determination process that includes determining a distribution of the acoustic features, based on the weight assigned to the frame of the voice signals.
