Clarity is more important than perfect accent
The purpose of pronunciation training is to make your interlocutor understand you easily. The accent itself is not a mistake and does not have to disappear completely.
Work first with the things that change the meaning or keep the listener asking questions: endings, stress, vowel length, and difficult consonant combinations.
Three training levels
Start with the sound in a single word, then move it into a short phrase and end with your own answer. This transition connects articulation with real speech.
Test yourself with recording and feedback, but don't draw a conclusion from one assessment. Compare multiple attempts under the same conditions.
A little plan for the week
Select two recurring difficulties. In the first days, work with words, then with phrases, and at the end of the week, write down a minute answer on a familiar topic.
SpeakRole helps to return weak points to individual voice exercises, so as not to waste the entire lesson on random mistakes.
