Abstract

　音声認識装置（１）は、音声分析部（１１）により変換された特徴量と、単語モデル生成部（１６）により生成された単語モデルとの各時刻における類似度を算出する音声照合部（１７）を備える。音声照合部（１７）は、単語モデル生成部（１６）により生成された単語モデルのうち、各時刻における類似度の中で最小の類似度あるいは各時刻における類似度から得られる全体類似度が第２閾値条件を満たし、かつ、発話音声の発声区間のうち、第１閾値条件に対応付けられた音素または音素列に対応する区間内の各時刻における類似度が第１閾値条件を満たす単語モデルを抽出し、抽出した単語モデルに対応する認識単語を認識結果として出力する。
