A hearing aid includes a microphone to convert sounds into electrical signals and a memory to store a plurality of voice prints and a plurality of sound-shaping instructions. Each of the plurality of sound-shaping instructions is associated with one of the plurality of voice prints. The hearing aid further includes a processor coupled to the microphone and the memory. The processor is configured to compare at least one sample from the electrical signals to the plurality of voice prints to identify a voice print. The processor selects sound-shaping instructions associated with the voice print and applies the sound-shaping instructions to selectively shape a portion of the electrical signals corresponding to the voice print to produce a shaped signal. The hearing aid further includes a speaker coupled to the processor and configured to reproduce the shaped signal as an audible output.
