One of my professors has a really interesting research area: Pittsburgh Speech or Pittsburghese as we call it. Last year, she asked me to help her with some podcasts that she was doing for her website.
Being a native Pittsburgher, I’m rather fluent in Pittsburghese, but the teachers that I had as a child made a point of encouraging us to be aware of our speech and not to slip into the dialect. I generally speak (or try to, anyway) in a relatively neutral tone of voice, but can turn Pittsburghese “on” when I want to.
Or when I’m drunk.
In any case, you can hear me on the podcasts for “nebby” and “dahntahn.” Check it aht.
