Abstract

A computer-implemented method of false keyphrase rejection comprises receiving a captured audio signal of human speech including one or more keyphrases that trigger an action. It also comprises detecting whether or not at least part of the speech is spoken by at least one computer originated voice. The method also has an operation of omitting the triggering of the action at least partly due to the computer originated voice being recognized in the speech.
