Claims37
A method for providing enhanced audio at an earpiece, the earpiece comprising a set of microphones and being configured to implement an audio filter for audio playback, the method comprising:
- collecting, at the set of microphones, audio datasets;
- processing, at the earpiece, the audio datasets to obtain target audio data;
- wirelessly transmitting, at one or more first selected time intervals, data representing the target audio data from the earpiece to an auxiliary processing unit;
- determining, at the auxiliary processing unit, a set of filter parameters based on the data representing the target audio data and wirelessly transmitting the set of filter parameters from the auxiliary processing unit to the earpiece;
- updating the audio filter at the earpiece based on the set of filter parameters to provide an updated audio filter wherein filter parameters are:
- determined at the auxiliary processing unit, wirelessly transmitted from the auxiliary processing unit to the earpiece, and used to update the audio filter at the earpiece at an update rate that is greater than once every 500 milliseconds during a time period when voice activity is detected to be present;
- using the updated audio filter to produce enhanced audio;
- and
- playing the enhanced audio at the earpiece.
An auxiliary processing device for supporting low-latency audio enhancement at a hearing aid over a wireless communications link, the auxiliary processing device comprising:
- a processor configured to execute, based on a filter update rate that is more than once every 500 milliseconds when voice activity has been detected, processing comprising analyzing first data corresponding to target audio wirelessly received by the auxiliary processing device from a hearing aid earpiece and, based on the analyzing, determining filter parameters for enhancing the audio;
- and
- a wireless link configured to receive the first data and to transmit the determined filter parameters to the hearing aid earpiece.
A hearing aid earpiece comprising:
- one or more microphones;
- a processor configured to execute processing to determine target audio data from audio datasets collected by the one or more microphones, the target audio being selected for wireless transmission to an auxiliary processing unit to identify filter parameters for enhancement of the target audio;
- and
- a wireless link adapted for sending data representing the target audio to the auxiliary processing unit and for receiving the identified filter parameters from the auxiliary processing unit
- wherein the processor is further configured to update an audio filter at the earpiece based on identified filter parameters wirelessly transmitted from the auxiliary processing unit to the earpiece at an update rate that is more than once every 500 milliseconds during a time period when voice activity is detected to be present, and wherein the processor is further configured to use the updated audio filter to produce enhanced audio at the earpiece.
