  • 単言語話者のための日英コードスイッチング音声の認識と翻訳 
    中山, 佐保子; サクティ, サクリアニ; 中村, 哲 (情報処理学会, 2021-03-15)
    会話の中で複数の言語が切り替わる現象は，コードスイッチングと呼ばれる．コードスイッチングは，言語が切り替わる場所や長さによってさまざまなものがある．従来の音声認識システムは，そのようなコードスイッチングを扱うのが難しく，解決すべき課題の1つであった．これまで研究されてきたコードスイッチング音声認識は，言語が混ざったコードスイッチング音声を，そのまま言語が混ざったコードスイッチングテキストに書き起こすことだけを目的とした．それは，結局，コ ...

    Word embeddings, which often represent analogic relations such as king − man + woman ≈ queen, can be used to change an attribute of a word, including its gender. To transfer the gender attribute of king to obtain queen in ...
  • 雑談対話応答における連続する事態の一貫性と対話継続性の関係 
    田中, 翔平; 吉野, 幸一郎; 須藤, 克仁; 中村, 哲 (一般社団法人言語処理学会, 2021-03-15)
    雑談対話システムの評価指標として，ユーザとの対話を継続させる働きを表す，対話継続性が挙げられる．対話モデルの先行研究において，対話継続性の向上には，システム発話の一貫性が重要であると考えられている．そこで本論文では，対話モデルより生成された応答候補を，対話中に含まれる事態の一貫性に基づいてリランキングする手法を提案する．提案手法は対話に含まれる事態の一貫性（「ストレスが溜まる」と「発散する」は関連した事態である，など）を考慮することで， ...
