METHOD, APPARATUS AND SYSTEM FOR LOW LATENCY AUDIO ENHANCEMENT
According to some embodiments, an ear-worn device, e.g., a hearing aid, is provided that operates to enhance audio signals detected by the ear-worn device. In some embodiments, the ear-worn device includes a microphone, a processing circuit coupled to the microphone, and an output signal generator coupled to the processing circuit. In some embodiments, a method for enhancing audio signals includes: detecting an audio signal with the microphone; as the audio signal is being detected, dividing the audio signal into a plurality of segments; enhancing the detected audio signal with the processing circuit of the hearing aid; and outputting the enhanced audio signal with the output signal generator. In some embodiments, enhancing the detected audio signal includes processing one or more of the segments of the detected audio signal with a neural network engine (NNE) of the processing circuit to obtain an output for enhancing the detected audio signal.
1 . A hearing aid comprising:
a microphone;
an output signal generator; and
a processing circuit coupled to the microphone and the output signal generator, wherein the processing circuit is configured to perform a method for enhancing audio signals with a hearing aid, the method comprising:
detecting an audio signal with the microphone of the hearing aid;
as the audio signal is being detected, dividing, with the processing circuit of the hearing aid, the audio signal into a plurality of overlapping segments, the plurality of overlapping segments comprising a first segment and a second segment, the first segment and the second segment sharing an overlapping portion;
after detecting the first segment, enhancing the overlapping portion by processing the first segment with a neural network engine (NNE) of the processing circuit to obtain a first output for enhancing the first segment including the overlapping portion;
transmitting the enhanced overlapping portion to the output signal generator for playback;
detecting the second segment during the playback of the enhanced overlapping portion;
after detecting the second segment including the overlapping portion and a non-overlapping portion, enhancing the non-overlapping portion of the second segment by processing the second segment with the NNE to obtain a second output for enhancing the second segment including the overlapping portion and the non-overlapping portion; and
transmitting the enhanced non-overlapping portion to the output signal generator for playback.
