چکیده

Speech conveys many things beyond content, including aspects of appraisal, feeling, and attitude that have not been much studied. In this work we identify 14 aspects of stance that occur frequently in radio news stories and that could be useful for information retrieval, including indications of subjectivity, immediacy, local relevance, and newness. We observe that newsreaders often mark their stance with prosody. To model this, we treat each news story as a collection of overlapping 6-second patches, each of which may convey one or more aspects of stance by its prosody. The stance of a story is then estimated from the information in its patches. Experiments with English, Mandarin, and Turkish show that this technique enables automatic identification of many aspects of stance in news broadcasts.

Considering 14 aspects of stance as they occur in radio news stories, we investigated the extent to which they could be inferred from prosody. By using time-spread prosodic features and by aggregating local estimates, many aspects of stance were at least somewhat predictable, wit...

Comparing lexical, acoustic/prosodic, structural and discourse features for speech summarization

We present results of an empirical study of the usefulness of different types of features in selecting extractive summaries of news broadcasts for our Broadcast News Summarization System. We evaluate lexical, prosodic, structural and discourse features as predictors of those news segments which should be included in a summary. We show that a summarization system that uses a combination of these...

A Web Classifier for Semantic Classification Between News and Sports Broadcasts

Lately, lot of work has been done in the area of content-based audio classification. In this paper we experiment on audio classification between sports and news broadcasts using the Average Magnitude Difference Function as the feature extractor and an LVQ1 neural network as classifier. The method proves robust and the results are reliable and could be further utilized in an automated web classi...
