Abstract
A sound processing device includes a first noise suppression unit configured to suppress a noise component included in an input sound signal using a first suppression amount, a second noise suppression unit configured to suppress the noise component included in the input sound signal using a second suppression amount greater than the first suppression amount, a speech section detection unit configured to detect whether the sound signal whose noise component has been suppressed by the second noise suppression unit includes a speech section having a speech for every predetermined time, and a speech recognition unit configured to perform a speech recognizing process on a section, which is detected to be a speech section by the speech section detection unit, in the sound signal whose noise component has been suppressed by the first noise suppression unit.
