ABSTRACT:
In a system for allocating a user identifier to a user of a voice-operated service, the user is requested (20) to utter words in a set of requested words. A speech recognizer (2) compares (24) each received word with a set of speech recognition templates, each template corresponding to the requested words. For each word uttered the speech recognizer generates (26) codes (W1, W2) which are the first and second best matched templates, and further generates (28) scores (D1, D2) indicating the extent of deviation of the received uttered words from the first and second best matched templates. The speech recognizer (2) then computes (32) a reliability criterion for each word by subtracting the scores (D1, D2) and comparing (34) the subtraction result with a threshold. Words having the greatest reliability criterion above the threshold are selected for the user identifier.
