This is quite funny. I have the remnants of man flu and my nose was mostly blocked which is probably the nasal sounding bit.
You misunderstand. I think I perceived a nasal sound because that's what I perceive when I hear my own recorded voice (which other people tell me objectively does not sound nasal). In other words, I think because your voice is very similar to mine, my brain tried to process it as it does my voice when I hear a recording of it.
Usually much clearer but you're right; it always sounds weird. I did a few years in a shitty goth band in my youth as vocalist (don't ask) and your voice always sounds completely odd. When everyone is out one day, so you don't look like an idiot, whack some headphones on and record yourself talking on your computer and play it back. This is how people hear you. The voice in your head is actually completely wrong.
I don't think so.
I used to (many years ago) work in recording and have occasionally been press ganged into doing guide vocals or backing vocals, I'd had the 'pleasure' of hearing my isolated voice replayed, at high volume, in a studio monitoring room. If it sounded anything like as awful as I perceive it to be, it would never have made it into the final mix, and I know it has.
Consequently, I've taken quite an interest in this over the years, and had quite a lot of discussions with people about it. As far as I can tell*, from asking a lot of questions of people who can hear me speak, the voice I perceive internally when I speak is close to what other people hear. One's brain somehow compensates for all the internal transmission of sound and manipulates your perception so that your perception of your own voice matches the external sound of your voice. If you like, a de-emphasis filter to compensate for all the bass emphasis, bone conduction and so on.
I think that's why one's own recorded voice sounds thin, your brain recognises it as yours and turns the internal 'corrective filtering' on, but lacks the physical stimulus that it's intended to filter, so filters out the elements that would normally be physically internal from the external physical signal. [That's the kind of sentence which, were I physically speaking, would require me to take a big gasp, right about now.]
Directly answering the questions (1) I do indeed. It's always weird. (2) I think we'd both sound normal to each other (3) shhhhhhh
Indeed, shhhhh...
Actually we should do a London TEA meet up
Could be a laugh.
