How Long Does It Take to Reduce an Accent in English?

Most adults hear a real difference in their own English within four to six weeks, and other people notice it within three months. Sounding close to a General American speaker in everyday conversation takes most of my students six to twelve months of steady work.

Why "reduce" is the right word and "remove" is not

I want to be honest before I give you numbers. After more than 1,500 online lessons, I have never met an adult who erased their accent completely, and I have never met one who needed to. The goal that pays off is intelligibility: being understood the first time, every time, in a meeting, on a phone call, in a job interview. Research on intelligibility (Munro and Derwing) has shown for years that a listener can find you very easy to understand while still hearing that you were born somewhere else. Those two things are separate.

So when I talk about timelines below, I mean the time it takes to remove the specific habits that cause misunderstandings, and then the extra time it takes to sound smooth and natural. If you want to read more about what changes and what does not, I wrote about it in whether accent reduction is worth it.

How long does it take to reduce an accent? The timeline my students follow

Every student is different, but the pattern below is what I see again and again with an adult at B1 or above who takes two lessons a week and practices most days.

The row that surprises people is the first one. In your first two weeks, your English will sound worse to you, because for the first time you can hear the gap between what you say and what an American says. That is progress. You cannot fix a sound you cannot hear.

What realistically changes in the first month

A month is enough to fix two or three high-frequency problems if you pick them well. In a first lesson I record a student reading a short paragraph and speaking freely for two minutes. Then I choose the errors that cost the most understanding, not the ones that are most noticeable. For a Spanish speaker that is often the vowel in ship versus sheep and the b/v confusion. For a Vietnamese speaker it is usually final consonants: like, light and lie all sounding the same. For a German speaker it is the w that comes out as v and the th that comes out as s or z.

Each of these is a physical habit, so it takes physical practice. A voiced TH needs the tongue tip touching the bottom of the top teeth, with air flowing past it. Most students can do it in isolation within ten minutes. Doing it inside the, that and they at conversation speed takes about three weeks of daily two-minute drills. That is the shape of the whole process: fast to learn, slow to make automatic.

What changes by month three

Around month three, the work moves from single sounds to the music of American English. This is where accents change the most, and it is the part learners almost never work on alone. Three things happen:

• Word stress stops being random. You say deVELop, not DEvelop, and hoTEL, not HOtel. Getting the stress right often matters more than getting every vowel right, which is why I wrote a whole guide to word stress in English.
• Reduction appears. Unstressed syllables shrink to a schwa. Especially becomes uh-SPESH-uh-lee instead of four equally loud syllables.
• Flap T becomes automatic in better, city and a lot of. If you have not started on it, the flap T guide is the place to begin, because it is the single fastest way to sound more American.

This is also the point where students tell me that people at work respond differently. Not because the accent is gone, but because the listener no longer has to work to follow them.

Six to twelve months: the accent gets light and stays light

The last stage is consistency. By month six most students can produce every target sound correctly when they concentrate. The remaining problem is what happens when they stop concentrating: on a stressful call, late in the evening, or when they get excited about a topic. The old habits come back.

Closing this gap is mostly volume. You need hundreds of correct repetitions of each sound in real sentences, with someone catching the slips you no longer hear. This is the phase where a student who practices 15 minutes a day and one who practices "when I have time" separate completely. The first is nearly done at month nine. The second is still at month-three level a year later.

The three factors that speed it up or slow it down

1. Your first language

The distance between your first language and American English decides how many sounds you need to build from zero. A Dutch or German speaker already has most English vowels and needs to fix a short list of consonants. A Japanese, Korean or Vietnamese speaker often needs to build the R/L contrast, several vowels and all final consonants, and each of those takes its own weeks. Neither group is "bad at accents." One simply has a longer list.

2. Minutes per day, not hours per week

Accent is a motor skill, like a tennis serve. Two hours on Sunday does far less than 15 minutes every day, because the muscles and the ear both need frequent, short reminders. My students who improve fastest have a fixed slot: brushing teeth, then five minutes of minimal pairs; commute, then ten minutes of shadowing. If you want the details on frequency, see how many lessons a week you really need. The short version: one lesson a week maintains, two a week changes an accent, three a week is for a deadline.

3. Feedback quality

This is the factor learners underestimate most. You cannot hear your own accent accurately. Your brain filters your speech through the sound system of your first language, so sink and think genuinely sound the same to you until someone trains your ear. Apps that show a green tick cannot tell you that your R is close but your tongue is too far back. A recording helps, but only if you know what to listen for. This is the part of the process where working with a tutor changes the timeline most: I hear the slip the moment it happens, I show you the mouth position on camera, and you fix it in the same sentence instead of repeating the error for another month.

4. Age (it matters far less than you fear)

Less than you think. The idea that adults cannot change their accent after a certain age comes from research on children who become native-like without instruction. Adults do not do that, but adults have something children do not: they can follow an explicit instruction like "put your tongue between your teeth" and practice it on purpose. My students range from their twenties to their sixties, and the ones in their fifties who practice daily beat the ones in their twenties who do not. Age changes almost nothing. Habits change everything.

How to know you are on schedule

Do not measure yourself by feeling. Measure with three simple checks:

1. The recording test. Record the same one-minute paragraph on day one and every four weeks. Listen to them side by side. The first month's difference is usually obvious.
2. The repeat count. Count how often someone asks you to repeat something in a week. My students often start at five or ten times and get to zero or one within three months.
3. The tired test. Record yourself at the end of a long day. When your target sounds survive tiredness, they are yours.

If you have been practicing for three months and none of these has moved, the problem is almost never effort. It is usually that you are practicing the wrong things or practicing an error very consistently. That is worth an hour with someone who can hear what is going on. You can book a first lesson for $25 and leave with a list of your top three problems and a plan. You can read more about how I work on my page.

What to do this week

Record yourself reading one paragraph out loud and speaking freely for one minute. Save both files with today's date. Then pick one sound you know is wrong, look up the mouth position, and drill it for five minutes a day in five real words. Do not add a second sound until the first one appears in conversation without thinking. Four weeks from now, record the same paragraph again. That comparison will tell you more about your timeline than any article can.
