Interdental L for Emphasis
Posted by Neal on December 30, 2013
“Who put Blackfish on our Netflix queue?” my wife asked.
“Oh, that was me. Entertainment Weekly recommended it.”
She didn’t want to watch it, though, so I ended up watching the documentary on killer whales in captivity myself, while I wrapped Christmas presents last week. It was a well-done film, and it was short enough that I even watched the DVD extras while I finished wrapping. They included an interview with marine biologist Dr. Naomi Rose, in a segment called “The Truth About Wild Whales.”
At the end of the interview, Rose was asked whether she thought Sea World should be shut down. She finessed the answer by saying that as a business, Sea World would do what its customers demanded, and offered this advice about how customers could make their wishes known:
They have to [pause] write a letter. [pause] Change their vacation plans. [pause] Let Sea World know they changed their vacation plans.
I had to put down the scissors and the wrapping paper and rewind the video to the beginning of that statement to watch and listen to it more closely. There it was! In the first sentence, Rose pronounced the /l/ at the beginning of the word letter in the way it’s described in texts on English phonetics: with the tip of her tongue behind her front teeth. But in the third sentence, she pronounced the /l/ at the beginning of let with the tip of her tongue between her top and bottom front teeth, in the same position as it would be if she were pronouncing /θ/ (as in thick) or /ð/ (as in this). In other words, she was pronouncing it as an interdental sound rather than an alveolar one.
This is a pronunciation that I learned about about 10 years ago from some college students in southern central Ohio. Now that I think more about it, I imagine that probably most English speakers pronounce /l/ this way when it comes right before /θ/ or /ð/, as in healthy or all this. I blogged about this pronunciation back in 2005, and linked to a post on the Linguist List on the subject. Since that link no longer works, here’s a fresh one. In the post, Mark Jones sums up responses from other list members, some of whom note that the interdental pronunciation seems to be used for emphasis, or when a speaker is hyperarticulating. That, I think, is what’s going on in Rose’s interview. Before she says let Sea World know, she pauses slightly and leans forward; and as she says it, she speaks at a higher volume.
Whether or not you’re interested in Dr. Rose’s interdental and alveolar /l/s, I recommend watching Blackfish. I wish I’d seen it before taking Adam to Sea World in San Antonio when we went down for my sister’s wedding in May.
