A Statistical Approach to Automatic Speech Summarization

Abstract: This paper proposes a statistical approach to automatic speech summarization. In our method, a set of words maximizing a summarization score indicating the appropriateness of summarization is extracted from automatically transcribed speech and then concatenated to create a summary. The extraction process is performed using a dynamic programming (DP) technique based on a target compression ratio. In this paper, we demonstrate how an English news broadcast transcribed by a speech recognizer is automatically summ… Show more

“…We tested whether the consolidation function in the summarization could contribute to the quality of machine translation in the IWSpS [14]. Five news stories, consisting of 25 utterances on average, of CNN broadcast news speech were transcribed and summarized at 40% and 70% extraction ratio [2]. The word accuracy of the ASR results was 78.4%.…”

“…We proposed a dependency score to avoid concatenating two words which do not have a dependency structure [2]. However, dependency detection of spontaneous speech is still challenging.…”

“…Variations of manual summarisation results are merged into a word network as shown in Figure 2, which is considered to approximately express all possible correct summarisations covering subjective variations. The word accuracy of automatic summarisation is calculated as the summarisation accuracy using the word network [5]:…”
