end-to-end 音声認識における出力ラベルにクラスラベルを導入した．End-to-end 音声認識は発音辞書を介すことなく文字を直接出力できるアプローチであり，主に英語音声認識の分野で研究例が報告されている．この end-to-end アプローチを日本語に適用する場合，文字総種の多さから英語に比べパラメータ数が膨大となり，限られた学習データでは学習サンプルが不足する文字も多数あるため，学習が難しい．本稿では connectionist temporal classification (CTC) 基準の日本語 end-to-end 音声認識において，出力ラベルにクラスモデルを導入してパラメータ数を削減すると同時にデータスパース性を解消し，言語モデルでクラスラベルを単語に復元する手法を提案する．日本語 end-to-end
