Forgive my asking , but am I wrong in taking it that you thus employ some form of digital vocalization software that "reads" the text out loud to you or do you have one of those motion braile pads that have pins that rise in the correct braille pattern to transmit each letter of text to fingertip in succession?

With this in mind in mind then the way "any" form of tuning a musical instrument , that doesn't use a visualization of each waveform , still requires heightened "listening" no matter one's level of eyesight.

As far as the "heightened" sense of listening it is *not* a steroetype at all ,but a matter of heightened *perception* due to lack of the distractions of sight. I always prefer to listen to complex orchestrated music with all lights out to get the full effect. It's just the way we are wired so your polite protestation
of "steroetyping" really sounds like a tree falling in forest with no one to hear it.

And to think all this over suggesting using one's own trained ear, perhaps aided by a tuning fork , to tune one's instrument.
