音声対話における発話タイミングの影響  [in Japanese] Influence of Response Timing in Speech Dialogues  [in Japanese]

Abstract

先行研究で行ってきた対話リズムに関する分析結果の妥当性を検証するために,発話タイミングに関する分析結果に基づいた音声対話を作成し,対話の自然性や合成音声の違和感,発話の聞き取りやすさなどを調査する知覚実験を行った.知覚実験1では合成音声による4ターンの短いタスク指向対話を,知覚実験2では実音声と合成音声の1分程度の長めの雑談対話を用いて実験を行った.その結果,発話における自然な発話タイミングが存在すること,発話内容に即した発話タイミングに自然性を感じるなど,対話リズムに関する分析結果の妥当性を示すことができた.

In order to examine the validity of the findings on the dialogue rhythm which we previously pointed out, we made some dialogue samples with various rhythm/utterance timing and evaluated them subjectively from the view points of naturalness of whole the dialogues, unnaturalness of synthesized speech, and intelligibility of the dialogues. We used short task-oriented four-turns dialogues using speech synthesizer in Experiment No. 1, and approx. one-minute chat-like dialogues in No. 2 using natural human utterances and synthesized voices. The results of these experiments supported our previous analysis that the utterance timing is important for natural dialogue and the timing of each utterance mainly depends on the contents of the utterance.
