Abstract: Embodiments generally relate to a device comprising at least one signal input component for receiving a bone conducted signal from a bone conducted signal sensor of an earbud; memory storing executable code; and a processor configured to access the memory and execute the executable code. Executing the executable code causes the processor to: receive the bone conducted signal; determine at least one speech metric for the received bone conducted signal, wherein the speech metric is based on the input level of the bone conducted signal and a noise estimate for the bone conducted signal; based at least in part on comparing the speech metric to a speech metric threshold, update a speech certainty indicator indicative of a level of certainty of a presence of speech in the bone conducted signal; update at least one signal attenuation factor based on the speech certainty indicator; and generate an updated speech level estimate output by applying the signal attenuation factor to a speech level estimate.

Abstract: Embodiments of the disclosure relate to methods, apparatus and systems for authentication of a user. The described embodiments relate to obtaining ear biometric data for a user to be authenticated. The ear biometric data comprises one or more features characteristic of the user's ear canal and an associated fit metric indicative of a positioning of a personal audio device relative to the user's ear canal, the personal audio device comprising a transducer for application of acoustic stimulus to the user's ear to obtain the ear biometric data. The user may be identified as a particular authorised user based on one or more features and the associated fit metric.
