Abstract
A received signal represents a user'"'"'s speech. A first speaker recognition process is performed on a first portion of the received signal, to obtain a first output result. A second speaker recognition process is performed on a second portion of the received signal that is different from the first portion of the received signal, to obtain a second output result. The second speaker recognition process is different from the first speaker recognition process. The first and second output results are combined to obtain a combined output result indicating a likelihood that the user is a registered user.

21. A method of processing a received signal representing a user'"'"'s speech, the method comprising:
-
performing a first speaker recognition process on a first portion of the received signal, to obtain a first output result; performing a second speaker recognition process on a second portion of the received signal, to obtain a second output result; combining the first and second output results to obtain a combined output result indicating a likelihood that the user is a registered user; determining if the indicated likelihood that the user is a registered user is higher than a threshold value; performing a speech recognition process on the second portion of the received signal to obtain a command contained in the second portion of the received signal; and acting on the obtained command if the indicated likelihood is higher than the threshold value. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 40)

39. A device for processing a received signal representing a user'"'"'s speech, for performing speaker recognition, wherein the device is configured to:
-
perform a first speaker recognition process on a first portion of the received signal, to obtain a first output result; perform a second speaker recognition process on a second portion of the received signal, to obtain a second output result; combine the first and second output results to obtain a combined output result indicating a likelihood that the user is a registered user; determine if the indicated likelihood that the user is a registered user is higher than a threshold value; perform a speech recognition process on the second portion of the received signal to obtain a command contained in the second portion of the received signal; and act on the obtained command if the indicated likelihood is higher than the threshold value.
