Patent

CA 1338613

In a telephone banking service, initial log-on (before service has identified the user) must use speaker-independent recognition (ie the speech recognizer 2 operates in accordance with a word template drawn from the population at large). Once the speaker is identified, the recognizer 2 employs a template specific to each individual speaker; this is much more accurate. The invention assists the log-on procedure by assigning each speaker a password consisting of a string of, for example, 5 digits which uniquely identify him, measuring the clarity with which the speaker recites each digit, compared to the standard template, and selecting his password from only those digits which he can clearly pronounce. The first digit may be used to indicate whether the speaker is male or female, and thereafter a respective "male" or "female" standard template may be employed.
