Abstract
A wearable audio device can include a microphone located to detect atmospheric sound including a user's voice. The device can include an acoustic vibration sensor located to detect sound including the user's voice conducted through the user's body. The device can include a body voice filter coupled to the acoustic vibration sensor. The device can include a filter parameter generator coupled to the acoustic vibration sensor and the body voice filter the filter parameter generator configured to generate parameters for the body voice filter based on a frequency characteristic of a signal obtained from the acoustic vibration sensor. The device can include a composite signal generator coupled to the body voice filter and the microphone and configured to generate a composite voice signal based on a low band signal obtained predominately from the body voice filter and based on a high band signal obtained predominately from the microphone.
