First, practice the pronunciation well
Pronunciation is a fundamental skill that helps you develop other skills such as listening, speaking, reading, writing and communicating effectively. Do it right the first time, because when you pronounce incorrectly, it is very difficult to correct. You should start with some basic grammar pronunciations such as American accent training, Ship or Sheep, ...
You should also try the American workshop training series. For good pronunciation, you need to repeat very well what you are hearing, practice in front of the mirror to adjust the mouth and tongue, pronounce it many times to find the correct tone.
However, there is a small but very important advice that you should practice pronunciation from the native speakers through tapes, music or movies to have the most standard speech. Or the Filipinos can pronounce English correctly and you can learn how to speak from them.
