Abstract
Presented herein are techniques for training a hearing prosthesis to classify/categorize received sound signals as either including a recipient's own voice (i.e., the voice or speech of the recipient of the hearing prosthesis) or external voice (i.e., the voice or speech of one or more persons other than the recipient). The techniques presented herein use the captured voice (speech) of the recipient to train the hearing prosthesis to perform the classification of the sound signals as including the recipient's own voice or external voice.

1-20. (canceled)
A method, comprising:
- obtaining, via a plurality of input devices, input audio signals in a sound environment that includes a voice of a user of a device and an external voice;
- distinguishing the voice of the user from the external voice in a plurality of time segments of the input audio signals;
- and
- executing a machine learning process to update operation of an own voice detector based on analysis of the input audio signals at the plurality of time segments.
A system, comprising:
- a plurality of input devices configured to receive input audio signals;
- an own voice detector configured to detect a voice of a user of the system in the input audio signals received by the plurality of input devices;
- and
- one or more processors configured to:
- determine a first plurality of time segments of the input audio signals that includes the voice of the user of the system and a second plurality of time segments of the input audio signals that includes an external voice;
- and
- execute a machine learning process to update operation of the own voice detector based on analysis of the input audio signals at the first plurality of time segments and at the second plurality of time segments.
One or more non-transitory computer readable storage media comprising instructions that, when executed by one or more processors, are configured to:
- obtain input audio signals that include a voice of a user;
- calculate a plurality of time-varying features from the input audio signals;
- receive a user input indicating which time segments of the input audio signals include the voice of the user;
- and
- update, based on an analysis of the plurality of time-varying features and the user input, operation of an own voice detector.
