Abstract
Certain aspects provide methods and apparatus for recovering audio quality of voice when processing signals associated with a wearable audio output device. A method that may be performed includes receiving, by an in-ear microphone acoustically coupled to an environment inside an ear canal of a user, an audio signal having a first frequency band, predicting high-frequency band information for the audio signal using a model trained using training data of known high-frequency bands associated with low-frequency bands, generating an output signal having a second frequency band based, at least in part, on the first frequency band of the audio signal and the predicted high-frequency band information for the audio signal, and outputting, by the wearable audio output device, the output signal having the second frequency band.
