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.
Claims18
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 that is different from the first portion of the received signal, to obtain a second output result, wherein the second speaker recognition process is different from the first speaker recognition process;
- applying respective weighting values to the first and second output results to form first and second weighted results respectively;
- combining the first and second weighted results to obtain a combined output result indicating a likelihood that the user is a registered user;
- and
- performing an antispoofing process on at least one of the first and second portions of the received signal to obtain an antispoofing score;
- wherein the weighting value applied to the second output result is determined by:
- excluding fragments of the second portion of the received signal that do not contain speech, and determining a total length of fragments of the second portion of the received signal that do contain speech;
- and
- setting the weighting value applied to the second output result based on the total length of fragments of the second portion of the received signal that do contain speech;
- and
- wherein at least one of the respective weighting values applied to the first and second output results is based on the respective antispoofing score obtained from the respective portion of the received signal.
