... Introduction An automatic speech recognition (ASR) system consists of acoustic models of speech sounds and of a statistical language model (LM). The LM learns the probabilities of word sequences from text ... number of retrieved rel- evant documents is optimized with respect to the number of queries submitted. The querying scheme is applied in the do- main of SMS text messages. Continuous speech recognition ... afford from the top of the list. However, the relevance of a query is dependent on the sequence of past queries (because of the decay factor). Find- ing the optimal order of the queries takes...

... modeling approach of Ponte and Croft (1998). Precision is measured on how many of the top five returned events are of the correct category. Figure 4 shows the precision of the video IR systems ... 4.3 Precision of Information Retrieval One of the most commonly used applications of ASR for video is to support information retrieval (IR). Such video IR systems often use speech tran- scriptions ... developed to model the distribution of topics discussed in a large corpus of documents. The model assumes that every document is made up of a mixture of topics, and that each word in a document...
