Repetition Builds the Pathway

A new sound travels a predictable road, and every learner walks the same four stages.

The four stages

1. Can't do it. The movement isn't available yet. You hear the difference but can't produce it.
2. Can do it with full concentration. You get it right when you're thinking hard about nothing else. One word at a time.
3. Can do it in a sentence. It survives being surrounded by other sounds — but it still costs attention, and it collapses when you speed up.
4. Can do it without thinking. It comes out that way by default, even when you're tired, even mid-argument. This is the finish line.

Most learners get to stage 2 quickly and then assume they're done. Stages 3 and 4 are where the actual hours go — and they're reached only by repetition.

What the reps are doing

Each accurate repetition strengthens a specific movement pattern and makes it a little easier to trigger next time. Your brain is essentially paving a road it will later travel automatically.

Two consequences worth knowing:

• Accurate reps are what count. Repeating a sound wrong paves the wrong road — and a well-paved wrong road is harder to abandon than no road at all. Slow down until you're sure it's right, then repeat.
• The road doesn't vanish overnight. Miss a few days and you'll be rusty, not reset. Progress is more durable than it feels.

Watch out for

• Practicing at speed too early — Fast reps at stage 2 mostly reinforce the old pattern. Speed is a reward for accuracy, not a route to it.
• Stopping at "I can do it" — Being able to do it and defaulting to it are two very different stages, separated by a lot of repetitions.

💡 You're not trying to produce the sound once. You're trying to make it the easiest thing your mouth can do.
