Abstract: A method and apparatus allows to accurately detect voice presence on a digitized communication line even in the presence of tone signals. The method includes analyzing digitized communication input signal by current blocks of 20ms (step 20), to define the stationary or non stationary state of any current block (step 21). Then an analysis on the states of the M last 20ms blocks (step 22) allows to give the final decision on voice presence or not.

Abstract: A method of indexing individual slides of a presentation comprises selecting a slide of a presentation (S2.1), determining one or more words in the selected slide (S2.2), counting the number of occurrences of each determined word (S2.3) in the selected slide, and storing an identifier for the selected slide (S2.4), the identifier comprising pairs of each of the determined words and the corresponding counted occurrences of the words. Such a simple identifier represents a summary of the slide and can allow users to define queries to search for individual slides.
