An advanced integrated architecture for wireless voicemail retrieval.

Abstract

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 a text summary of their voicemail in realtime 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 which has been trained 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 complete voicemail value-added service.
