Practical exercise
Practice reading ten fictional syllables or short words with short and long sounds, then compare the difference in timing and flow.
Real-life example
A learner reciting a memorized passage tends to rush through long vowels. After practicing prolongation, the recitation sounds smoother and more controlled.
Mini lab
Build a timing chart with three columns: short sound, prolonged sound, and your self-rating. Record yourself reading fictional examples and note where you shortened or overextended the sound.
