What the numbers say
Spanish, Italian, Portuguese and French: 600–750 hours
The FSI puts these in its easiest group for English speakers: about 24 weeks of full-time study for Spanish, Italian and Portuguese, and about 30 weeks for French. Shared vocabulary and familiar grammar do a lot of the work.
German: about 900 hours
Around 36 weeks in the FSI's estimate. The vocabulary is related to English, but four cases, three genders and verb placement take longer to become automatic in speech.
Japanese and Mandarin Chinese: about 2,200 hours
Roughly 88 weeks for each, in the FSI's hardest group — and it marks Japanese as harder than most languages even within that group. Much of it is the writing system: basic spoken Japanese or Mandarin is reachable long before you can read a newspaper. Mandarin adds tones, which have to be produced, not just recognised, from the first week.
Learning English: 350–600 hours to conversation
Cambridge English estimates about 350–400 guided learning hours to reach B1, the level where everyday conversation opens up, and 500–600 hours for B2. How close your first language is to English changes this a great deal.
Those are hours to professional fluency, not to your first conversation
The FSI figures describe diplomats trained to do their jobs in the language, in intensive full-time courses. Simple, real conversation — introductions, plans, opinions, the story of your week — arrives long before that, and it arrives fastest for people who speak from the start.
How to get there faster
Speak from the first week
Recognising a word and producing it are different skills. Reading and listening build recognition; the hours that count toward speaking are the ones you spend saying sentences out loud.
Little and often beats long and rare
Fifteen minutes a day is more than 90 hours of speaking a year, which is more than most learners ever do. Daily sessions also give memory the spacing it needs to hold on to what you learn.
Get corrected on the spot
Speaking without feedback makes your mistakes fluent. A correction that arrives while the sentence is still in your head is the one that sticks.
Measure conversations, not lessons completed
Set targets you can hear: a five-minute conversation about your job, a story about your weekend. The CEFR levels (A1 to C2) describe exactly these abilities, which makes them a better yardstick than a streak.
What a realistic first three months looks like
For a language close to English, with fifteen to twenty minutes of speaking most days.
Weeks 1–2: survival phrases
Greetings, introducing yourself, asking someone to repeat or slow down. Short, fixed phrases said out loud until they come without thinking.
Weeks 3–6: talking about yourself
Your work, your family, your plans and your week, in the present and simple past. This is where most of your first real conversations will happen.
Weeks 7–10: questions and opinions
Asking questions back, giving a reason, agreeing and disagreeing. Conversations stop being interviews and start going both ways.
Weeks 11–13: handling the unexpected
Role-plays of real situations — a restaurant, a doctor, a job interview — where the other side does not follow your script. This is the point at which many learners describe themselves as conversational.
Common questions
- What is the fastest language to learn to speak?
- For English speakers, Spanish, Italian and Portuguese are among the quickest by the FSI's estimate, at around 600 classroom hours to professional proficiency, with French close behind at about 750.
- Can I become conversational in three months?
- In a language close to English, with daily speaking practice, you can hold simple everyday conversations within about three months. Fluent, effortless conversation takes considerably longer.
- How many hours a day should I study a language?
- Consistency beats volume. Fifteen to thirty minutes of active speaking every day, plus whatever listening and reading you enjoy, is sustainable and effective.
- Does knowing one foreign language make the next one faster?
- Usually, yes, especially within a family: Spanish speakers pick up Portuguese and Italian quickly. You also already know how you learn best, which saves time on every language after the first.
