A method provides a voice in binaural sound to a user. A wearable electronic device (WED) selects head-related transfer functions (HRTFs) based on a distance between eyes of the user. A digital signal processor (DSP) in the WED processes the voice with the HRTFs to generate the voice in the binaural sound that localizes at a sound localization point (SLP) at a location in empty space to the user.
