Method and system for generating a speech recognition dictionary based on greeting recordings in a voice messaging system

摘要

A system and a method for generating a speech recognition dictionary that can be used in a telephone system having speech recognition capabilities, in particular capabilities to effect a connection when the calling party utters the name of a subscriber (called party). The method generates transcriptions associated to respective vocabulary items in the speech recognition dictionary from audio greetings recorded by the telephone system subscribers. Normally such audio greetings are used in voice messaging applications. Typically, the greetings are played before allowing callers to leave messages in a voice mailbox of subscribers. An individual greeting is audio information that contains the name of the subscriber. This audio information is processed to generate a transcription associated to a vocabulary item in the speech recognition dictionary, representative of the subscriber name.
