If you still pronounce Thai words and release ending consonant sounds of ก(-k), บ(-p), and ด(-t), Thai people likely do not understand you. I got quite some inquiries regarding the ending consonant sounds, hence I created a podcast to help you understand the concept of ending consonant sounds as well as created an exercise to help you differentiate the unreleased ending sounds. This will be helpful!

These ending consonant sounds should not be released. Close your throat and hold your breath. 

To improve your pronunciation, it's better to see the mouth shape of a native Thai pronouncing Thai words. Check out my Thai Pronunciation Series and see free preview lessons to get started improving your Thai sounds and become more confident to speak Thai.
