Apologies in advance for my generalizations. I do not intend this question to be racist in any way.
Do black people in non-USA, mostly-white, English-speaking countries have a distinct manner of speaking that differs from the way the white citizens speak?
Here in the US, it often easy to tell when an unseen speaker is black, simply by the way they speak. I’m not talking about grammar or slang so much as simply inflection and tone. Is this the case in, say, England?
In the rare instances where I’ve heard a British black man speak (say, while watching the Olympics) I honestly cannot hear any difference between the way he speaks and the way a white British man speaks. I assume that a British person would hear any difference much better than I could.
Of course, I’m limiting this to black people who are several generations removed from “immigrant” status. i.e., English is the native language for them, for their parents, for their grandparents, and their ancestral “native tongue” is no longer a significant influence on their accent.
Most of the time, there are regional accents within a country - in the US, it’s fairly easy to distinguish between a “Southerner” and a “New Englander” and a “West Coaster”. But it seems that I can identify a “black” voice, regardless of where that person is from. I live in the Pacific Northwest, and a few years ago I shared an apartment with a black man close to my age, who was born and raised in St. Louis, MO. I also sat in a college classroom with some younger black men who were mostly from the Seattle area. While my classmates and my roommate differed in the slang they used, and in many speech patterns, they shared the same “tone” of voice that was immediately identifiable as “black”. Same deal with the older black man who sometimes plays drums with one of the musical groups I play with.
Heck, there are very few black people in my small town, and yet even the ones I’ve met who were born and raised here sound a bit different from the local whites.
And yes, I’m perfectly aware of black people who don’t “sound black”. Television news anchors for example (though I suspect their lack of “black” voices is often due to voice training in broadcasting school); former San Diego Padres batting legend Tony Gwynn - I was really surprised by his voice.
