Summary:PROBLEM TO BE SOLVED: To provide a process for collecting the identity of a telephone caller. SOLUTION: In one embodiment, a personalized context free grammar (CFG) (212) is created for each potential call recipient (210), and is configured to support the identification of incoming callers using speech recognition. Each CFG (212) incorporates an indication of high probability callers and probability weights in each CFG are altered accordingly. When a recipient (210) receives a call (202), the relevant CFG (212) is applied in association with a speech recognition application (222) to enable at least a preliminary identification of the caller. In another embodiment, the caller confirms the identifications. In accordance with one embodiment, a standard caller number notification service function (224) is used if possible at least to assist in a caller identification process when available. In accordance with still another embodiment, provided is an intelligent call routing function (226) using speech recognition enhanced caller identification. COPYRIGHT: (C)2005,JPO&NCIPI
