n-gram 単位で抽出する手法と構文解析を用いて抽出する手法について比較を行った．抽出した句のうちテストデータに出現するものに対して人手によって翻訳を行うことで，対象ドメインに頻出する英日の頻出フレーズ対を作成した．作成した英日フレーズ対を翻訳モデルへ学習させることで対象ドメインへの適応を行った．学習の手法として学習コーパスとして追加する手法とフレーズテーブルに追加する手法を比較した．性能の比較を行うために評価基準 BLEU を用いた．結果として書き起こしの英語文を日本語へ翻訳した結果，構文解析によって抽出し，作成した英日フレーズ対をフレーズテーブルに追加する手法において BLEU10.5 を得ることができ，ベースラインのモデルの BLEU10.2
