| Abstract(in English) | This paper proposes a new method of automatically summarizjng speech by extracting a limited number of relatively important words from its automatic transcription according to a target compression ratio for the number of characters. To determine a word set to be extracted, we define a sumnlarization score consisting of a topic score(significance measure) of words and alinguistic score(likeihood) of the word concatenation. A set of words maximizing the score is efficiently selected using a dynamic programming(DP) technique. In order to evaluate the summarization scores of the summarized sentences obtained from the same original sentence using the various summarizing ratio, a normalization factor is applied to the summarization score.Japanese broadcast news speech transcribed using a large vocabulary continuous speech recognition system was summarized. As a result 86% of important words in the original speech were correctly included in the summarizing sentences and 72% of the smmarizing sentences could maintain the meanings of the original speech under the 60 70% summarization condition. |
