Second, an effective and robust combination of statistical with prior knowledge sources for term weighting is used to extract information from the decoder's output in order to deliver summaries to the message recipients via a GSM Short Message Service (SMS) gateway. 1. INTRODUCTION As the emphasis in cellular networks changes from voice-only communication to a rich combination of content based applications and services, speech recognition can provide access to several types of information through a number of portable solutions, including mobile phones and personal digital assistants.
