Abstract: There is described a system and method for performing biometric authentication, preferably voice biometric authentication. The system has a host device such as a mobile phone and a coupled headset device. The headset device is arranged to receive audio, and to cryptographically protect the audio before transmission to the host device for verification and biometric authentication.

Abstract: A method of speaker verification comprises receiving an audio signal representing speech. While the audio signal is being received, features of the received audio signal are extracted. The extracted features, of at least a part of the received audio signal corresponding to the speech of at least one speaker, are summarised, and the summarised extracted features are stored. In response to a request for a speaker verification process relating to at least one enrolled user, the speaker verification process is performed using the previously summarised features.

Abstract: A method of sending information between first and second modules connected by a signal bus comprises generating a clock signal in the first module, and imposing the clock signal on a first line of the bus. A first pattern of bit values is transmitted from the second module to the first module on a second line of the bus, during first half-periods of each period of said clock signal. A second pattern of bit values is transmitted from the first module to the second module on the second line of the bus, during second half-periods of each period of said clock signal, wherein the second half-periods of each period of said clock signal are different from the first half-periods of each period of said clock signal. Information can then be transmitted from the first module to the second module by altering the second pattern of bit values; and information can be transmitted from the second module to the first module by altering the first pattern of bit values.

Abstract: A method of operation of a speaker recognition system comprises: performing a speaker recognition process on a received signal; disabling the speaker recognition process when a first speaker has been identified; performing a speech start recognition process on the received signal when the speaker recognition process is disabled; and enabling the speaker recognition process in response to the speech start recognition process detecting a speech start event in the received signal.

Abstract: One aspect provides a method in an audio data transmission module. The method comprises: obtaining an audio data stream comprising speech from a user to be authenticated, the audio data stream comprising a plurality of data segments; obtaining a voice biometric authentication result relating to the speech in one or more first data segments of the audio data stream; generating data-authentication data for one or more second data segments of the audio data stream; generating one or more cryptographically signed packets comprising the voice biometric authentication result and the data-authentication data; and outputting the one or more cryptographically signed packets.

Abstract: Embodiments of the disclosure provide methods and apparatus in which a biometric authentication score generated as the result of a biometric authentication algorithm is compared to a threshold value that can be dynamically varied as required to provide a variable level of security. For example, the threshold value may be varied in dependence on the semantic content of a voice signal, and/or the context in which the voice signal was acquired. Authentication of the signal may be initiated in parallel with speech recognition, such that the appropriate threshold value is only determined after authentication has already begun.

Abstract: A method of processing received data representing speech comprises monitoring the received data to detect the presence of data representing a first portion of a trigger phrase in said received data. On detection of the data representing the first portion of the trigger phrase, a control signal is sent to activate a speech processing block. The received data is monitored to detect the presence of data representing a second portion of the trigger phrase in said received data. If the control signal to activate the speech processing block has previously been sent, then, on detection of the data representing the second portion of the trigger phrase, the activation of the speech processing block is maintained.

Abstract: This application relates to transfer of microphone data from a microphone (101, 102, 102a, 201) to a processing module, such as voice biometric authentication module (111) in a secure manner, such that the receiving module can trust that the received audio is genuine. An authentication module (203) is configured to receive microphone data (DM) representative of an audio signal received at the microphone (201), and generate from the microphone data, authentication data (DA) for certifying that the microphone data did pass via the authentication module. The first authentication data (DA) comprises information relating to distinguishing characteristics of the audio content of the microphone data and may, for instance be an acoustic fingerprint of the audio content. The authentication data, may be cryptographically signed or encrypted and sent with the microphone audio to allow a receiver to verify that the audio is genuine and the content has not been substantially altered. The process may be robust to processing of the data that results in imperceptible changes in the audio content.
