Abstract
There is provided a sound processing device including a background noise estimation unit configured to estimate a background noise of an input signal, a noise suppression unit configured to suppress the background noise of the input signal based on a result obtained by estimating the background noise, a feature quantity calculation unit configured to calculate a feature quantity based on the input signal in which the background noise is suppressed, and a consonant detection unit configured to detect a consonant from the input signal based on the feature quantity.
