Transcribing broadcast news for audio and video indexing

Some existing applications that could greatly benefit from new technology are the creation and access to digital multimedia libraries (disclosure of the information content and content-based indexation, such as are under exploration in the OLIVE project), media monitoring services (selective dissemination of information based on automatic detection of topics of interest) as well as new emerging applications such as News on Demand and Internet watch services. Such applications are feasible due to the large technological progress made over the last decade, benefiting from advances in microelectronics that have facilitated the implementation of more complex models and algorithms. Automatic speech recognition is a key technology for audio and video indexing. Most of the linguistic information is encoded in the audio channel of video data, which once tranTranscribing Broadcast News
