Abstract

本研究では,認識誤りを選択操作だけで訂正することが可能な音声入力インタフェース「音声訂正」を提案する.音声訂正では,ユーザが音声入力を開始すると,認識結果を単語ごとに区切った表示と,区切られた各区間に対する他候補(競合候補)が発話の最中から次々と画面に描画される.競合候補の個数はその区間の曖味さを反映し,音声認識結果として信頼性の低い箇所ほど,多数の候補が表示される.ユーザはそれを見ながら,発話中あるいは発話終了後に正しい候補を選択するだけで訂正が可能となる.実験の結果,音声訂正は誤りのほとんどを訂正することができ,本インタフェースの有効性を確認した.

In this paper, we propose a novel speech input interface function, called "Speech Repair", where recognition errors can be easily corrected by selecting candidates. Along the speech input, this function shows not only the usual speech-recognition result but also other competitive candidates. Each word in the result is separated by line segments and accompanied by other word candidates. A user who finds a recognition error can simply select the correct word from the candidates for that temporal region. To overcome the difficulty of generating appropriate candidates, we adopted a confusion network that can condense a huge internal word graph of a large vocaburaly continuous speech recognizer. In our experiments, almost all recognition errors were repaired and the effectiveness of Speech Repair was confirmed.
