Patent
CA 2105034
A facility is provided for allowing a caller to place a telephone call by merely uttering a label identifying a desired called destination and to charge the telephone call to a particular billing account by merely uttering a label identifying that account. Alternatively, the caller may place the call by dialing or uttering the telephone number of the called destination or by entering a speed dial code associated with that telephone number. The facility includes a speaker verification system which employs cohort normalized scoring. Cohort normalized scoring provides a dynamic threshold for the verification process making the process more robust to variation in training and verification utterences. Such variation may be caused by, e.g., changes in communication channel characteristics or speaker loudness level.
Une installation permet à un appelant de faire un appel téléphonique simplement en prononçant le nom d'une étiquette qui identifie une destination d'appel désirée et de facturer l'appel à un compte particulier simplement en prononçant le nom d'une étiquette qui identifie ce compte. L'appelant peut également faire l'appel en composant ou en prononçant le numéro de téléphone de l'appelé, ou encore en entrant un code de composition abrégée associé à ce numéro. L'installation comprend un système de vérification de haut-parleur qui utilise le modèle normalisé cohorte. Ce modèle offre un seuil dynamique pour le processus de vérification, ce qui rend ce processus plus robuste en ce qui concerne les variantes de prononciation, du point de vue de la formation et de la vérification. Ces variantes peuvent être dues, par exemple, à des modifications des caractéristiques des voies de transmission ou du volume du haut-parleur.
