Read the sentence out loud. Your browser writes down what it heard. Red words are the ones it got wrong, and those are usually the words to practice.
Play the sentence, then record yourself saying it the same way. Play both back to back to hear the difference. Copy the rhythm and the melody, not only the words.
Tip: record right after the model while it's still in your ear.
These word pairs differ by one sound. Pick the sound you find hardest, listen to the pairs, then test your ear and your mouth.
The loud, long syllable matters more for being understood than any single sound. Tap the syllable you think gets the stress.
