Abstract
A voice switching device includes a learning unit configured to learn a background noise model expressing background noise contained in a first voice signal, based on the first voice signal, while the first voice signal having a first frequency band is received; a pseudo noise generation unit configured to generate pseudo noise expressing noise in a pseudo manner, based on the background noise model, after a first time point when the first voice signal is last received in a case where a received voice signal is switched from the first voice signal to a second voice signal having a second frequency band narrower than the first frequency band; and a superimposing unit configured to superimpose the pseudo noise on the second voice signal after the first time point.
