Method and apparatus for hearing assistance in multiple-talker settings
Disclosed herein, among other things, are systems and methods for hearing assistance in multiple-talker settings. One aspect of the present subject matter includes a method of operating a hearing assistance device for a user in an environment. A parameter is sensed relating to facing orientation of a talker in communication within the environment. Parameters related to location and talking activity of a talker can also be used. In various embodiments, facing orientation, location, and talking activity of the talker are estimated based on the sensed parameter. A hearing assistance device parameter is adjusted based on the estimated facing orientation, location, and talking activity of the talker, according to various embodiments.
1. A method of operating a hearing assistance device for a user in an environment, the method comprising:
sensing parameters related to facing orientation of a talker of a plurality of talkers in communication with the user, location of the talker, and talking activity of the talker within the environment using a sensor providing parameters to a processor of the hearing assistance device;
synthesizing a directional marker signal based on the sensed parameters using the processor; and
using the directional marker signal to control processing of the hearing assistance device using a sound processing unit of the hearing assistance device.
2. The method of claim 1 , wherein using the directional marker signal to control processing includes steering an adaptive directional system.
3. The method of claim 1 , wherein using the directional marker signal to control audio processing includes activating a binary masking noise reduction based on the direction marker signal.
4. The method of claim 1 , wherein, if no talker is identified, synthesizing the directional marker includes synthesizing an idle marker.
5. The method of claim 1 , wherein synthesizing a directional marker signal includes performing a cluster analysis.
6. The method of claim 1 , wherein synthesizing a directional marker signal includes updating the directional marker signal in real time to follow a change in target direction relative to the user.
7. The method of claim 1 , wherein when the directional marker signal changes, the sound processing unit synthesizes a notification signal that is localized in the direction of the marker signal, to draw the user's attention to a target direction.
8. The method of claim 7 , wherein the notification signal includes one or more of a tonal beep or a short burst of broadband noise.
9. The method of claim 1 , wherein sensing parameters related to facing orientation, location, and talking activity of a talker in communication with the user includes using a camera.
10. The method of claim 1 , wherein sensing parameters related to facing orientation, location, and talking activity of a talker in communication with the user includes using an accelerometer.
11. A hearing assistance system including a hearing assistance device for a user in an environment, the system comprising:
a sensor configured to sense parameters related to facing orientation of a talker of a plurality of talkers in communication with the user, location of the talker, and talking activity of the talker within the environment;
a decision module configured to synthesize a directional marker signal based the location of the talker with respect to the user using the sensed parameters; and
a sound processing unit configured to use the directional marker signal to control sound processing of the hearing assistance device.
12. The system of claim 11 , wherein the sound processing unit is configured to steer an adaptive directional system using the directional marker signal.
13. The system of claim 11 , wherein the sound processing unit is configured to activate a binary masking noise reduction based on the direction marker signal.
14. The system of claim 11 , wherein the hearing assistance device includes a hearing aid.
15. The system of claim 14 , wherein the hearing aid includes an in-the-ear (ITE) hearing aid.
16. The system of claim 14 , wherein the hearing aid includes a behind-the-ear (BTE) hearing aid.
17. The system of claim 14 , wherein the hearing aid includes an in-the-canal (ITC) hearing aid.
18. The system of claim 14 , wherein the hearing aid includes a receiver-in-canal (RIC) hearing aid.
19. The system of claim 14 , wherein the hearing aid includes a completely-in-the-canal (CIC) hearing aid.
20. The system of claim 14 , wherein the hearing aid includes a receiver-in-the-ear (RITE) hearing aid.
21. The system of claim 14 , wherein the hearing aid includes an invisible-in-canal (IIC) hearing aid.
