（STD ： Spoken Term Detection） の研究が盛んに行われている．検索精度を向上させるために，高順位候補を含むドキュメント内の全ての候補の距離を有利にする方式など [1] [2] が提案されている．本稿では，同一講演内で話題の内容に関連してクエリと共起する単語をクエリの関連語と呼び，関連語は当該講演内に複数回出現すると仮定する．クエリの関連語を特定するため，本稿では Word 2 vec を用いた単語の分散表現が有効と考え，音声データの単語認識結果中の各単語を Word Vector 化し，クエリの Word Vector と比較し，類似度を求めることでクエリの関連語を取得する．一方，未知語クエリは単語認識結果に出現しないため Word Vector を算出できない．本稿では，クエリで Web 検索し得られたテキスト中の出現単語も Word 2 vec に用いてクエリの意味的情報を補い，未知語クエリの Word Vector を算出できるようにする．これにより，未知語クエリに対応させることができ，クエリの関連語を的確に求められると考える．以上のようにして，Web 検索と Word Vector を用いてクエリの関連語を特定し，関連語を含むドキュメント内の全ての候補の距離を有利にすることで検索精度の向上を図る．講演音声を対象とした NTCIR-10，12 の Formal Run の 2 種のテストセットを用いて評価した結果，両テストセットで検索精度が平均 3.2 pt 向上した．先行手法と併用することで更に精度が平均 1.4 pt
