....main approaches are found in the literature. The most obvious is to use a large vocabulary continuous speech recognition system (LVCSR) to produce a word string. Then, search algorithms are applied for keyword detection in that string [22] This approach is considered as giving the best results [23, 24]. Another common approach is based on the use of keyword and filler models. These latest represent the non keyword intervals of the utterance [23] Models can be sub word keyword models like phonetic models or can be whole word models. 25] gives a very interesting overview of re scoring methods ....

An original approach based on a HMM based acoustic ....
