Praat on the Web Praat on the Web

This system is an implementation of the widely used speech analysis tool Praat as a web application with an extended functionality for feature annotation. In particular, Praat on the Web addresses some of the central limitations of the original Praat tool and provides (i) enhanced visualization of annotations in a dedicated window for feature annotation at interval and point segments, (ii) a dynamic scripting composition exemplified with a modular prosody tagger, and (iii) portability and an operational web interface. Speech annotation tools with such a functionality are key for exploring large corpora and designing modular pipelines.

Online Patent summarization Demo Online Patent summarization Demo

Online demo of the patent summarization system. The system performs a linguistic analysis of the patent document, selects the most important passages and combines them in an abstractive summary.

The Demo is the result of several european projects and the experience in our group on patent processing.
