How Long Does It Take to Perfect English Vowel Sounds?

Perfecting English vowel sounds typically takes 8 to 12 weeks of consistent, focused practice. Because English has more vowel sounds than most languages, mastering them requires daily listening, repetition, and mouth-position awareness.

In the first few weeks, learners usually identify problem pairs—like ship/sheep or full/fool. By week six, muscle memory starts forming, making correct vowels feel more natural. Around week ten, most speakers can maintain accuracy in real conversations.

Progress depends on ear training as much as mouth movement. Listening to native models and recording your own speech helps reinforce subtle distinctions in sound length and clarity.
