  The human voice typically ranges from 85 Hz to 255 Hz for adults, with males often around 85 to 155 Hz and females between 165 to 255 Hz.

    In these sources they are talking about the fundamental frequency of human Speech F~0~. Which is one important indicator but I don’t think this band is sufficient for comprehension. Record yourself, apply a low-pass filter with cut frequently at 300Hz and check for yourself if this is enough to understand. It might be enough to make out some words, but I doubt it’s enough to hear clearly.

      Maybe machine learning can infer the missing wave information (like Fourier transforming partial waveforms??
