Speech and Spoken Document

rogress in both speech and language processing has spurred efforts to sup-port applications that rely on spoken—rather than written—language input.A key challenge in moving from text-based documents to such “spoken doc-uments” is that spoken language lacks explicit punctuation and formatting,which can be crucial for good performance. This article describes differentlevels of speech segmentation, approaches to automatically recovering segment bound-ary locations, and experimental results demonstrating impact on several language pro-cessing tasks. The results also show a need for optimizing segmentation for the endtask rather than independently.
