Abstract

A speech recognition system front end interface to provide a subscriber voice control over many voice mail functions. The speech recognition system converts spoken instructions into DTMF instructions for voice mail systems while allowing prompts form the voice mail system and DTMF tones from the subscriber to pass through without any interference by the speech recognition system. To accomplish these pass through functions, the speech recognition system sets up what is know as a hairpin connection between the subscriber, the speech recognition system and the voice mail system.
