I hope this is a good place to put this topic. I am hearing on TV commercials something strange - When speaking, the lady is pronouncing her T and D and S with a distinct whistle sound, and its a very sharp sound. What causes this?

By the way, the commercial is for Kidde fire extinguishers. She is a teacher and while speaking, its very strange and annoying.

Can anyone explain why someone pronounces their T and D like an S?

Are you referring to a lisp?

It's a bad recording, she does pronounce "d" correctly.

Probably a question for one of our resident dentists, but it likely has to do with the formation of her teeth, either natural or as the result of dental work.

A long set of fangs, might be catching her breath and making the whistling sound? I had an unusually long and pointed set of upper canines and I whistled a bit, when I pronounced certain syllables. But later, these teeth were crowned, with shorter and more blunt tips and the whistling no longer occurs.

Looks like she has a gap between her teeth, which is likely the cause of it.

I'm not sure it's inherent in her speech. I think there is something happening in the frequency response of the audio mix. In some scenes it is present and in some not, so it might just be the way she is miked. Microphone positioning is sometimes very sensitive to overtones, like popping Ps.
