Abstract: Received data representing speech is stored, and a trigger detection block detects a presence of data representing a trigger phrase in the received data. In response, a first part of the stored data representing at least a part of the trigger phrase is supplied to an adaptive speech enhancement block, which is trained on the first part of the stored data to derive adapted parameters for the speech enhancement block. A second part of the stored data, overlapping with the first part of the stored data, is supplied to the adaptive speech enhancement block operating with said adapted parameters, to form enhanced stored data. A second trigger phrase detection block detects the presence of data representing the trigger phrase in the enhanced stored data. In response, enhanced speech data are output from the speech enhancement block for further processing, such as speech recognition.

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 translation: 在由信号总线连接的第一和第二模块之间发送信息的方法包括在第一模块中产生时钟信号，并将时钟信号施加在总线的第一行上。 在所述时钟信号的每个周期的前半个周期期间，第一模式的位值从总线的第二行从第二模块发送到第一模块。 在所述时钟信号的每个周期的后半个周期期间，第二模式的比特值在总线的第二线路上从第一模块发送到第二模块，其中所述时钟信号的每个周期的第二半周期 与所述时钟信号的每个周期的前半个周期不同。 然后可以通过改变比特值的第二模式来将信息从第一模块传送到第二模块; 并且可以通过改变比特值的第一模式从第二模块向第一模块发送信息。

Abstract: There is provided a method in a peripheral device comprising one or more microphones. The peripheral device is connectable to a host device via a digital connection. The method comprises: receiving, from the one or more microphones, an audio data stream relating to speech from a user, the audio data stream comprising a stream of data segments; and, responsive to detection of a trigger phrase in one or more first data segments of the audio data stream: effecting activation of the digital connection; and transmitting one or more biometric features extracted from the one or more first data segments to the host device via the digital connection for use in a voice biometric authentication process.

Abstract: Embodiments of the invention provide methods and apparatus for monitoring the routing configuration within an electronic device such that a biometric authentication process can be carried out without interference from other components of the device, such as may occur when the device has become infected with malware for example. The invention may provide a codec or speaker recognition processor, coupled to receive biometric input data, comprising a security module that determines whether a routing configuration complies with one or more rules. The security module may be implemented to prevent genuine biometric data from being output from the speaker recognition processor, and/or to prevent spoof biometric data from being inserted into the authentication module.

In response, enhanced speech data are output from the speech enhancement block for further processing, such as speech recognition. Detecting the presence of data representing the trigger phrase in the received data is carried out by means of a first trigger phrase detection block, detecting the presence of data representing the trigger phrase in the enhanced stored data is carried out by means of a second trigger phrase detection block, and the second trigger phrase detection block operates with different, typically more rigorous, detection criteria from the first trigger phrase detection block.
