Abstract

本発明は　雑音環境に頑健な音声検出システム、音声検出プログラムを提供する。 フレーム単位に切り出された入力信号から特徴量を算出する特徴量算出部２と、フレーム単位に算出された特徴量から音声区間・非音声区間を仮判定する仮音声・非音声判定部３と、音声区間継続長閾値あるいは非音声区間継続長閾値を、フレーム毎に求められた特徴量と、特徴量に関する閾値との比を用いて決定し、前記決定された音声区間継続長閾値と非音声区間継続長閾値を用いて音声区間・非音声区間を再判定する音声・非音声判定部６を備え、音声区間継続長閾値と非音声区間継続長閾値をフレーム毎に求められる特徴量と特徴量に対する閾値とを用いて決定することで、フレーム毎に求まる特徴量に信頼の置けるときには整形ルールの縛りを弱くし、逆にフレーム毎に求まる特徴量に信頼の置けないときには整形ルールの縛りを強くすることで、雑音環境に依存せずに音声検出を行う。
