How long does it take to learn to speak English?

"Speak English" can mean ordering a meal or leading a meeting, and those two goals are hundreds of study hours apart. So the honest answer has two parts: which level you are aiming for, and how many hours you have already put in.

This page takes the hour estimates for each level, A1 to C2, from a Cambridge University Press paper, lists what the same paper says makes learning faster or slower, and shows how to turn the numbers into a timeline for your own week. They are planning figures, not a promise.

A quick example with Airi

How long will it take me to speak English well?

It depends on where you are now and how much you speak each week. How long have you been learning English?

I learn English since five years, but I am still slow when I speak.

"I've been learning English for five years." That's a solid base. What slows you down more: starting a sentence or finding the right word?

How long it takes to learn English: the short answer

A Cambridge University Press paper, "How long does it take to learn a foreign language?" (revised January 2018), estimates that a motivated adult needs about 350 to 490 guided learning hours to go from beginner to B1, enough for most travel situations, and about 530 to 750 hours to reach B2, where regular conversation with fluent speakers becomes quite possible. At one hour a day, every day, that is about 12 to 16 months for B1 and one and a half to two years for B2.

Those figures describe an adult whose first language uses the same script as English, with good motivation, good learning resources and well-trained teachers. The paper says they are based on its experience of developing courses, the views of experienced teaching professionals and other published guidance, and that they have not been validated through empirical research. Treat them as a planning estimate, not a promise.

Hours to learn English at each level, A1 to C2

"Guided learning hours" means class time plus guided self-study such as homework. The speaking descriptions are our shortened versions of the "spoken interaction" row of the CEFR self-assessment grid, which is published on the European Union's Europass site. The last column is our own arithmetic, not Cambridge's: the hours divided by one hour a day, every day.

Level	What speaking looks like	Guided hours from beginner	At one hour a day
A1	Simple questions and answers with a patient listener	90 to 100	About 3 months
A2	Short, routine exchanges on familiar topics	190 to 250	6 to 8 months
B1	Most travel situations; unprepared talk on familiar topics	350 to 490	12 to 16 months
B2	Spontaneous conversation; you can explain and defend your views	530 to 750	1.5 to 2 years
C1	Flexible social and professional use, little searching for words	730 to 1,050	2 to 3 years
C2	Any conversation without effort, with fine shades of meaning	1,030 to 1,450	3 to 4 years

Each step costs more than the last: A2 is 100 to 150 hours beyond A1, but C2 is 300 to 400 beyond C1.

For test takers, the paper cites research by Elder and O'Loughlin (2003) on students taking full-time intensive English courses at language centers in Australia and New Zealand. They gained about half an IELTS band on average after 10 to 12 weeks, or 200 to 240 hours of instruction, and progress varied from student to student.

What makes learning English take longer or shorter

Factor	What the Cambridge paper says	What to do about it
Your first language	The more it differs from English in script, sounds, grammar and vocabulary, the longer learning takes. There is some indication that the effect is strongest at elementary levels.	If your language is far from English, plan for the top of each range or more. A slow start is not a lack of talent.
Intensity	Two hours a week with little self-study and long breaks between terms is less effective than a more intensive program.	Practice a little every day, and keep going through school or work breaks.
A clear goal	Learners with a clear picture of themselves using the language outside class are likely to learn faster.	Write one sentence: "I want to run a 30-minute client call in English."
Extra practice	Students who add significant self-study beyond class and homework should progress faster.	Add English you choose yourself: podcasts, reading, conversations.

The same paper gives two more examples that show how far context moves the numbers. For teenagers with low motivation, it puts B1 at 530 to 680 hours and B2 at 750 to 950. For primary school children whose first language uses a different script, taught by a general teacher instead of an English specialist, it puts B1 at 780 to 980 hours. The paper presents all three as illustrations, not as the most common cases.

Be skeptical of "fluent in 30 days." The paper notes that claims about accelerated learning are usually anecdotal, and that substantially more research is needed before shorter timelines can be recommended.

How to estimate your own English learning timeline

Name the goal. "I want to travel without a translator" points to B1. "I want to work or study in English" usually points to B2 or higher.
Find your level honestly. In the level table, pick the highest row you could manage on a tired day.
Subtract. From A2 to B2, for example, the Cambridge ranges leave 340 to 500 guided hours.
Divide by your real weekly hours. At seven hours a week, 340 to 500 hours takes 49 to 71 weeks, roughly 11 to 16 months. At four hours a week, it takes 85 to 125 weeks, roughly 20 to 29 months.
Count hours, not years. Two class hours a week over a 35-week school year is 70 hours a year, so "I studied English for six years" may mean about 420 class hours, with long breaks in between.
Check every three months. Record yourself for two minutes answering "What do you do, and what do you like about it?" and compare the recordings.

Where Airi fits in the hours it takes to learn English

The hour counts are for English as a whole, and the paper notes that learners pick up the four skills at different rates. If you read English well but freeze in conversation, speaking is the skill that is short of hours. Airi is for that part: a voice partner in the browser who answers out loud and shows one small fix at a time.

Open with your goal: "I'm preparing for meetings at work. Ask me one question at a time about my job."
Answer in two or three full sentences, not one word.
When a small fix appears, say the corrected sentence out loud once, then keep going.
Before you stop, ask: "What should we talk about next time?" She remembers your name and your last topic.
Write down the minutes you spoke. Airi does not track your hours or test your level.

The free credits last about eight minutes, enough for one short conversation; after that, credits come in one-off packs with no subscription. Airi is not a course or a teacher. At A1 or A2, start with a class, a teacher or a structured textbook, and add Airi as extra speaking time.

How to get the most from it

Round up, not down

The adult ranges assume good teaching, good materials and steady motivation. If one of those is missing, plan with the higher number.

Expect a plateau in the middle

The Cambridge paper describes a familiar plateau at intermediate level: 100 new words add less to what you can say than they did at A1, so progress feels slower even though you are still learning.

Give speaking its own slot

The hour ranges are for all four skills together. If speaking is the one behind, decide in advance which minutes of your week are for talking out loud.

Frequently asked questions

How long does it take to become conversational in English?

If conversational means B1 on the CEFR scale, where you can join unprepared conversations on familiar topics, a Cambridge University Press paper (revised 2018) estimates about 350 to 490 guided learning hours from beginner for a motivated adult with good teaching. That is about 12 to 16 months at an hour a day. If you already understand English well, you are not starting from zero, so count only the levels you still have to climb.

Can I learn to speak English in 3 months?

From zero, three months at an hour a day is about 90 hours, which the Cambridge estimates put at around A1: simple questions and answers with a patient listener. If you already read and understand English, you are not starting from zero, and three months of regular speaking practice is a reasonable block to plan and then review. Nobody can honestly promise a level by a date.

What makes learning to speak English faster?

According to the Cambridge paper: more intensive study with regular review instead of two hours a week and long breaks, extra practice beyond class and homework, and a clear picture of what you want to use English for. For speaking in particular, you need time spent actually speaking. Airi gives you a partner for that whenever you have a few minutes, with one small fix at a time.

How many hours does it take to reach B2 in English?

About 530 to 750 guided learning hours from beginner, in the Cambridge University Press example of a motivated adult whose first language uses the same script as English. Going from B1 to B2 alone is put at 180 to 260 hours. The paper says these figures have not been validated through empirical research.

How long does it take to raise an IELTS score?

Research by Elder and O'Loughlin (2003), cited in the Cambridge paper, found that students on full-time intensive English courses in Australia and New Zealand gained about half a band on average after 10 to 12 weeks, about 200 to 240 hours of instruction, with progress varying from student to student. Airi can give you speaking practice for the test, but she does not predict band scores.

Is Airi free to try?

Yes. You get 600 free credits when you sign up with Google, about eight minutes of speaking. After that, credits come in one-off packs of USD 5, 10 or 20, with no subscription.
