Patent ID: 8326612

Claim:
A non-speech section detecting device generating a plurality of frames having a given time length on the basis of sound data obtained by sampling sound, and detecting a non-speech section having a frame not including voice data based on speech uttered by a person, the device comprising: a calculating part calculating a bias of a spectrum obtained by converting sound data of each frame into components on a frequency axis; a judging part judging, when the calculated bias of the spectrum has a positive value or a negative value, whether the bias is greater than or equal to a given threshold or alternatively smaller than or equal to a given threshold; a counting part counting the number of consecutive frames judged as having a bias greater than or equal to the threshold or alternatively smaller than or equal to the threshold; a count judging part judging whether the obtained number of consecutive frames is greater than or equal to a given value; and a detecting part detecting, when the obtained number of consecutive frames is judged as greater than or equal to the given value, the section with the consecutive frames as a non-speech section.
