Publication number: US20220103921A1
Application number: 17/545,456

Abstract:
Described embodiments generally relate to a signal processing device for on ear detection for an earbud. The device comprises a first microphone input for receiving a microphone signal from a first microphone, the first microphone being configured to be positioned within an ear of a user when the earbud is being worn; a second microphone input for receiving a microphone signal from a second microphone, the second microphone being configured to be positioned outside the ear of the user when the earbud is being worn; a signal generator configured to generate a signal for acoustic playback from a speaker configured to be positioned within the earbud; and a processor. The processor is configured to receive at least one first microphone signal from each of the first microphone input and the second microphone input, and compare the first microphone signals to determine the on ear status of the earbud; determine that the on ear status of the earbud cannot be sufficiently determined, generate a signal for acoustic playback from the speaker, receive a second microphone signal from the first microphone input, and compare the second microphone signal to the generated signal to determine the on ear status of the earbud.

Publication number: US20220093111A1
Application number: 17/543,980

Abstract:
A method of analysis of an audio signal comprises: receiving an audio signal representing speech; extracting first and second components of the audio signal representing first and second acoustic classes of the speech respectively; analyzing the first and second components of the audio signal with models of the first and second acoustic classes of the speech of an enrolled user. Based on the analyzing, information is obtained information about at least one of a channel and noise affecting the audio signal.
