Abstract
A method, apparatus, computer program product and service for directory dialer name recognition. The directory dialer has a directory of names and a first name grammar and a second name grammar representing phonetic baseforms of first names and second names respectively. The method includes: receiving voice data for a spoken name after requesting a user to speak the required name; extracting a set of phonetic baseforms for the voice data; and finding the best matches between the extracted set of phonetic baseforms voice data and any combination of the first name grammar and the second name grammar. The method can further include: checking the best match against the directory of names; if the best match does not exist in the directory, informing the user and prompting the next best match as an alternative; and if the best match does exist in the directory, forwarding the call to that best match.
