Abstract: The disclosure provides apparatus and methods for enabling transactions to be conducted securely using audio output signals. One embodiment provides an electronic device, comprising: an audio output; an audio input; interface circuitry; and processing circuitry, configured to: receive, from a remote server via the interface circuitry, an indication of a transaction requested by a user of the electronic device; output one or more output messages for playback via the audio output, the one or more output messages comprising an audio transaction confirmation message comprising an indication of the transaction; receive, from the audio input, one or more input messages spoken by the user, the one or more input messages comprising a transaction confirmation response message; perform a voice biometric authentication algorithm on at least one of the one or more input messages to determine whether the user is an authorised user of the electronic device; and responsive to a determination that the user is an authorised user of the electronic device, output to the remote server, via the interface circuitry, a response message comprising an indication of the audio transaction confirmation message and an indication of the transaction confirmation response message.
