Abstract: A detection method, performed prior to applying a voice recognition function to a voice signal uttered by a user and picked up by a set-top box, includes the steps of: verifying that the television set is switched on, and if not, producing a first command for switching the television set on; verifying that the set-top box is an active HDMI source of the television set, and if not, producing a second command for causing the set-top box to become the active HDMI source of the television set; while the television set is switched on and the set-top box is the active HDMI source of the television set, producing a request to start the voice recognition function.
