It is fairly common, yes. In particular, people tend to have extra warm/loving tones when talking to their pets and babies. Otherwise, you read the room and figure out what tone you want to take. Sound and/or tone aside, “code switchting”, which is a dialectic change, is also common and sometimes considered a modern requirement for people needing to get things done in both African American and White American cultures.

I’m trans, I’ve got so many different voices going on right now.

I think everyone does that basically.

i have a few different fake voices and then my real voice that i use on my cat.

Of course. We have different voice register according to the situation. It’s coded differently. When I joke around with my wife I will be more like moaning, talking to a cop I will use my formal voice (in my belly). Speaking english I will speak with my throat, speaking french I will speak an octave lower. It’s also a matter of frequency and noise environment. If you’re in heavy traffic or in a club or something, my nose voice works better than my belly voice, that’s too low. But on the other hand, my wife was having an interview the other day for TV and she was asked to speak in a lower voice otherwise she’d “sound like a little girl”.

I’ll talk like a whole different character sometimes if someone really 'bro’y starts talking to me lol. I don’t know who I am in Buddhist philosophy they say there is no one true ‘self’, it’s dependent on the conditions and interactions of that monent.

A fun lesson in an english class I had was examining our ‘voice’, we speak in a different tone but also use different words with different groups. I’ve heard people say that people doing that are fake or just trying to act different to fit in or something but I think it’s a natural useful thing to help bond, even birds use different calls with those they’re familiar with and strange birds.

I used to have an fairly nasal voice with bonus autistic monotone, when needed I would switch on more emoting, facial expressions, and then add higher voice for friendly, lower voice for formal as needed. Then I drank for a decade, and now I’m too tired and sober to mask anymore so I just have a monotone whiskey gravel at all times and everyone thinks I’m meaner than I am

I do, but I attribute this to autistic masking.

I’m especially bad when it comes to mimicking people’s speech and mannerisms, even down to their accents, when I speak to them. For example, I live in the southern US but I am noticeably “accentless.” However, if I speak to a stranger, I tend to affect a southern accent.

Sometimes I am worried someone will think I am trying to code switch, but really I’m just trying to seem normal and doing a horrendous job.

My phone voice is so feminine that people often call me ma’am on the phone. I’ve worked at an AutoZone and had a customer walk in asking about a woman on the phone and I am HIDING IN THE BACK because there were no women employed at that store. In general my voice tends to be on the higher register, but when I try to sound extra polite it just sounds that way.

Yup. Been masking for as long as I can remember. It leads to me picking up people’s accent unconsciously.

I also wanted to be voice actor growing up, and I can sing, so I love just making voices up.

I want to do voice training, too, so hopefully i’ll have more in the bag and it won’t affect my identity in any way, nope.

Not really. Though I have a naturally higher pitched voice for a male so I learned how to speak with vocal fry/larynx dropped to mimic a baritone.

I think everyone does it, I hate my phone customer service voice I go from passing to noep.
