What is an IPA chart and how will it help my pronunciation?

The International Phonetic Alphabet (IPA) Chart is a scientific map of the human mouth. It catalogs every sound possible in human speech by assigning a specific symbol to a specific physical action.

Unlike the Vietnamese alphabet, where some vowels/diphthongs can have the same sound, the IPA operates on a 1:1 ratio: one symbol always equals one exact sound.

Example: The letter “i” (i ngắn) or “y” (y dài) can be written as [i] . In the Northern accent, there is no difference in length or pitch between them.

Besides, most speech errors occur because you are substituting a foreign sound with the “closest” sound in your native language. The IPA chart shows you that these sounds are physically different.

Example: If you struggle with the Vietnamese ư [ɯ], the chart shows it is in the exact same spot as u [u], but your lips must be unrounded. You stop guessing and start following “coordinates.”

This system is specifically powerful for Vietnamese because it reveals the hidden physical actions that standard spelling misses.

For example, it helps you identify that different spellings like ‘ia’ and ‘iê’ are actually the same physical sound.

It also provides a visual graph for tones, using vertical lines and curves to show your voice exactly where to start and end its pitch. By following these coordinates, you stop substituting Vietnamese sounds with English ones and start training your mouth to move with the precision of a native speaker.

Take 5: Have you listened to the sounds? Try to repeat them. Continue until you feel more confident.
