How long does shadowing take to work?
Last updated
There is no fixed number of days. What you can count on is the order things change in: the clips you practise first, then reading aloud, and spontaneous speech last.
The short answer
Most people hear a difference in the clips they practise within the first session or two, because repetition makes those few sentences smoother almost immediately. A change in how you sound when you speak freely is slower, and is best judged over weeks and months, not days. How fast it comes depends on how often you practise, how different your target accent is from the way you speak now, and how closely you listen when you compare recordings.
What changes first
- The practised clip. After 15 or 20 passes, your timing and melody on that clip get much closer to the speaker’s. This is real, but it is mostly memory of that one clip.
- Rhythm and intonation in general. After a few weeks of daily clips, the stress patterns and melody start to carry over into other sentences, especially when you read aloud.
- Individual sounds. Vowels and consonants that don’t exist in your first language often take longer, because you first have to hear the difference reliably.
- Spontaneous speech. When you’re thinking about what to say, old habits come back. This is the last thing to change, and the most important test.
Why daily beats long sessions
Accent is a motor habit, like a tennis stroke. Short, frequent practice gives your memory more chances to consolidate than one long session a week. Fifteen minutes a day is a good default; on busy days, five minutes keeps the habit alive.
How to tell whether it’s working
Day-to-day comparisons are misleading: you have good and bad days, and you get used to your own voice. Instead:
- Record a baseline before you start: a few sentences read aloud, a minute retelling something you watched, and a minute answering a question you haven’t prepared.
- Repeat the same tasks every four weeks or so, and listen to the baseline and the new recording back to back.
- Ask other listeners to say which recording sounds closer to the target accent, without telling them which one is newer.
Euno Shadowing builds this in: a baseline, then check-ins at weeks 4, 8 and 12 with the same tasks. Twelve weeks is a checkpoint for comparing, not a promise that you’ll be finished.
Why progress stalls, and what to do
- Clips that are too long or too fast. If you can’t keep up after five passes, cut a shorter clip.
- Copying words, not melody. Exaggerate the rises, falls and long syllables until it feels slightly theatrical.
- Never comparing. Record a pass and look at it next to the original. Pitch lines and lag show what your ears miss.
- Changing speakers too often. Stay with one voice for a few weeks so the patterns can settle.
- Only shadowing. Use the accent in your own sentences too: retell what you shadowed in your own words.
