Most people when they hear a recording of themselves are surprised to hear that [their voice sounds differently](http://www.bbc.com/future/story/20130913-why-we-hate-hearing-our-own-voice) from what they hear inside their head.
Does someone with perfect pitch hear themselves differently?
Are they so well attuned musically to know how to adjust to the difference?

Your voice sounding differently in recordings isn’t a change in pitch, but in timbre. When you sing, you don’t produce one single pure tone, but a complex series of overtones that gives each voice a slightly different sound. The difference between how you hear yourself and how a recording of you sounds is a change in which overtones you hear more than others. The pitch stays the same. This is why you will sometimes see people cover one ear while singing harmony, so they can better hear their own voice and keep it in tune.
