Abstract

　時間の経過とともに変化していく話者本人の発話音声の特徴に対応して、精度良く話者を認識することができる話者認識装置、音響モデル更新方法及び音響モデル更新処理プログラムを提供する。 　発話した話者が当該適応話者モデルに対応する登録話者であると判定された場合には、適応話者モデルを更新する。このとき、算出された音声特徴量を適応音声特徴量記憶部１１に記憶させ、適応音声特徴量記憶部１１に記憶された音声特徴量のうち、現時点から過去に遡ってＫ個の音声特徴量で初期話者モデルを適応処理を行うことによって、新たな適応話者モデルを作成し、この新たな適応話者モデルを登録話者モデル記憶部９に記憶させ、登録話者モデル記憶部９に記憶された新たな適応話者モデルを用いて、発話した話者が当該適応話者モデルに対応する登録話者であるか否かを判定する。
