i speak english good. But sometimes, people don't understand some of my words. For the most part, they do. My speach teacher told me to work on pronouncing my "D" and "T" can anyone help? Or do they sell something online that can help me. I would like to speak as clear as possible.

I depends on what your native language is, to know how to help you speak better pronounced english. In english, I can tell where you are from by your pronounciation of english. Each nationality learning english has their own specific accent. For instance, the japanese can't pronounce the letter L. The chinese cant pronounce the letter R. And it goes to all other nations, each has its own pronounciation accent. So I cant help you because I dont know other than D and T being your problem. For that just say
the two letters in repeated repeated manners:

"DO, DO, DO , DO, DO , DO, DO
and then
"TO, TO, TO, TO TO TO,
and try to distinguish each in your pronounciation.
THEN when you think you can pronounce D and T correctly, prove it by repeating:
"DO, TO, DO, TO, DO, TO, DO, TO.....
Good luck
