Hearing assistance system with own voice detection
First Claim
1. A hearing assistance device configured to be worn by a wearer having an ear and an ear canal, comprising:
- a first microphone to produce a first microphone signal;
a second microphone to produce a second microphone signal;
a voice detector configured to detect a voice of the wearer and produce an indication of detection in response to the voice of the wearer being detected, the voice detector including an adaptive filter allowing for the voice of the wearer to be distinguished from other sound sources based on the first microphone signal and the second microphone signal;
a sound processor configured to produce an output signal having directionality using the first microphone signal, the second microphone signal, and the indication of detection; and
a receiver configured to produce an audible signal using the output signal.

Abstract
An example of an apparatus configured to be worn by a person who has an ear and an ear canal includes a first microphone adapted to be worn about the ear of the person, and a second microphone adapted to be worn at a different location than the first microphone. The apparatus includes a sound processor adapted to process signals from the first microphone to produce a processed sound signal, a receiver adapted to convert the processed sound signal into an audible signal to the wearer of the hearing assistance device, and a voice detector to detect the voice of the wearer. The voice detector includes an adaptive filter to receive signals from the first microphone and the second microphone.

12. A method for operating a hearing assistance device worn by a wearer, comprising:
-
receiving first and second microphone signals using first and second microphones mounted on different locations of the hearing assistance device; processing the first and second microphone signals to produce an output signal having directionality; detecting a voice of the wearer using an adaptive filter configured to allow for the voice of the wearer to be distinguished from other sound sources based on the first microphone signal and the second microphone signal; adjusting the processing of the first and second microphone signals in response to the voice of the wearer being detected; and providing an audible signal to the wearer based on the output signal. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
