Call Voice Processing Apparatus, Call Voice Processing Method and Program
First Claim
1. A call voice processing apparatus, comprising:
- an input correction unit that corrects characteristics of a first input sound input from a first input apparatus to characteristics of a second input sound input from a second input apparatus that are different from the characteristics of the first input sound;
a sound separation unit that, when a plurality of sounds is contained in the second input sound, separates the second input sound into a plurality of sounds;
a sound type estimation unit that estimates sound types of the plurality of sounds separated by the sound separation unit;
a mixing ratio calculation unit that calculates a mixing ratio of each sound in accordance with the sound type estimated by the sound type estimation unit;
a sound mixing unit that mixes the plurality of sounds separated by the sound separation unit in the mixing ratio calculated by the mixing ratio calculation unit; and
an extraction unit that extracts a specific sound from the first input sound corrected by the input correction unit using a mixed sound mixed by the sound mixing unit.

16. A call voice processing method, comprising the steps of:
-
correcting characteristics of a first input sound input from a first input apparatus to characteristics of a second input sound input from a second input apparatus that are different from the characteristics of the first input sound; when a plurality of sounds is contained in the second input sound, separating the second input sound into a plurality of sounds; estimating sound types of the plurality of separated sounds; calculating a mixing ratio of each sound in accordance with the estimated sound type; mixing the plurality of separated sounds in the calculated mixing ratio; and extracting a specific sound from the corrected first input sound using a mixed sound obtained by the mixing.
