Abstract

 制御手段2のフレーム生成部20は、音データから所定の時間長のフレームを生成し、スペクトルの偏倚/パワー/ピッチ導出部21aは、音データを周波数軸上の成分に変換したスペクトルの偏倚、音/データのパワー及び音データのピッチの少なくとも一を導出し、更に、導出された値について、変化量導出部21bが、前フレームとの変化量を導出する。スペクトルの偏倚としては、音データの0次の自己相関関数に対する1次の自己相関関数の比を用いる。非音声区間検出部22bは、前記変化量が所定の閾値以下であると判定した場合、該判定の成立するフレームが連なる数が所定数以上であるときに、前記フレームが連なる区間を非音声区間として検出する。また、単発的に変化量が大きい区間は非音声区間から除外し、更に、当該区間が非音声区間にはさまれている場合は、判定を覆して非音声区間として検出する。
