Gain control for a hearing aid with a facial movement detector
First Claim
1. A method of controlling an output of a hearing aid worn by a wearer, comprising:
- receiving an input audio signal from a microphone;
receiving a facial movement indication from a facial movement detector measured contemporaneously with the input audio signal;
determining whether the facial movement indication matches a first movement pattern associated with the wearer speaking;
applying a first gain profile to the input audio signal for generating an augmented audio segment in response to determining that the facial movement indication matches the first movement pattern associated with the wearer speaking;
applying a second gain profile to the input audio signal for generating the augmented audio segment in response to determining the facial movement indication does not match the first movement pattern associated with the wearer speaking; and
outputting the augmented audio segment.

Abstract
Methods, systems and devices are provided for controlling a hearing aid. Embodiments include receiving an input audio signal from a microphone. Also, a facial movement indication may be received from a facial movement detector measured contemporaneously with the input audio signal. Additionally, whether a first movement pattern associated with the wearer speaking is a movement match to the facial movement indication may be determined. In this way, a first gain profile may be applied to the input audio signal for generating an augmented audio segment in response to determining the first movement pattern is the movement match to the facial movement indication. Also, a second gain profile may be applied to the input audio signal for generating the augmented audio segment in response to determining the first movement pattern does not match the facial movement indication. Thus, the augmented audio segment may be output.

10. A hearing aid for adjusting sound heard by a wearer, comprising:
-
a facial movement detector configured to detect facial movements of the wearer; a microphone configured to receive an input audio signal in response to detecting sound; a speaker for outputting an augmented audio segment; a memory having stored thereon first movement pattern data associated with the wearer speaking; and a processor coupled to the facial movement detector, the microphone, the speaker and the memory, wherein the processor is configured with processor-executable instructions to perform operations comprising; receiving the input audio signal from the microphone; receiving a facial movement indication from the facial movement detector measured contemporaneously with the input audio signal; determining whether the facial movement indication matches the first movement pattern; applying a first gain profile to the input audio signal for generating the augmented audio segment in response to determining that the facial movement indication matches the first movement pattern; applying a second gain profile to the input audio signal for generating the augmented audio segment in response to determining the facial movement indication does not match the first movement pattern; and outputting the augmented audio segment to the speaker. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

28. A non-transitory computer readable storage medium having stored thereon processor-executable instructions configured to cause a processor of a hearing aid worn by a wearer to perform operations for controlling an output of the hearing aid, the operations comprising:
-
receiving an input audio signal from a microphone; receiving a facial movement indication from a facial movement detector measured contemporaneously with the input audio signal; determining whether the facial movement indication matches a first movement pattern associated with the wearer speaking; applying a first gain profile to the input audio signal for generating an augmented audio segment in response to determining that the facial movement indication matches the first movement pattern associated with the wearer speaking; applying a second gain profile to the input audio signal for generating the augmented audio segment in response to determining the facial movement indication does not match the first movement pattern associated with the wearer speaking; and outputting the augmented audio segment. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36)
