Work is currently being carried out on a speech database

constructed in order to study speech rhythm in connection with speech rate. The database, BonnTempo-Corpus, and the Praat based analysis tools, BonnTempo-Tools, are a powerful

instrument for examining various aspects of recently proposed rhythm measures (e.g. %V, C, nPVI, rPVI, etc.) in relation to speech rate among a wide range of languages and speakers.

First observations pose new problems on traditionally not well classifiable languages like Czech.
