An advanced integrated architecture for wireless voicemail data retrieval

This paper describes an alternative architecture for voicemail data retrieval on the move. It is comprised of three distinct components: a speech recognizer, a text summarizer and a WAP push service initiator, enabling mobile users to receive text summaries of their voicemail in real-time without an explicit request. Our approach overcomes the cost and usability limitations of the conventional voicemail retrieval paradigm which requires a connection establishment in order to listen to spoken messages. We report performance results on all different components of the system that has been trained and tested on a database containing 1843 North American English messages as well as on the duration of the corresponding data path. The proposed architecture can be further customized to meet the requirements of a complex voicemail value-added service
