A method, comprising: in a handsfree device coupled to a data processing device: monitoring at least one received audio stream for occurrence of at least one keyword, wherein the handsfree device has been configured to recognize the at least one keyword; upon recognition of the at least one keyword, establishing a first connection between the handsfree device and the data processing device for launching a voice interface in the data processing device; and sending audio data, which are received after the recognition of the at least one keyword, to the data processing device via the established first connection for responding to the sent audio data, by the data processing device, via the voice interface, characterized in that the method further comprises, in the hands free device: during a keyword configuration operation, inputting the at least one keyword; sending the inputted at least one keyword to the data processing device for recording, by the data processing device, of the inputted at least one keyword; receiving, via a second connection, the recorded at least one keyword from the data processing device; and performing configuration of the handsfree device, utilizing the recorded at least one keyword, for recognizing the at least one keyword in the at least one received audio stream, the method further comprising entering the keyword configuration operation when: the handsfree device is first coupled to the data processing device; the data processing device discovers that the handsfree device is capable of monitoring the at least one received audio stream for occurrence of the at least one keyword; the data processing device determines that the handsfree device has not been configured to recognize the at least one keyword; and the data processing device causes the handsfree device to enter the keyword configuration operation by prompting and requesting input of the at least one keyword via the handsfree device. in a handsfree device coupled to a data processing device: monitoring at least one received audio stream for occurrence of at least one keyword, wherein the handsfree device has been configured to recognize the at least one keyword;
