How Long Does It Take to Learn a Language?

2026-10-24

Trying to get by on a trip to Seoul or Madrid? Or learning a language so you can finally keep up at the dinner table with your partner’s family, or catch what your friends are actually saying to each other? How long it takes to learn a language comes down almost entirely to what you’re trying to do with it.

Let’s break down realistic timelines for Spanish, French, Mandarin, Korean, and Japanese, and how Polyspeech gets you there faster by getting you speaking from day one.

How Long Language Learning Actually Takes

Most language learning apps throw around numbers from the U.S. Foreign Service Institute (FSI), which puts professional fluency at 550 to 2,200 class hours, depending on the language.

But Polyspeech can reduce those class hours significantly because you learn to speak from day one. If you think about it, babies learn to speak naturally without flashcards, textbooks, or lengthy classes. How so? By speaking and listening.

Of course, there are different levels to being able to converse with others, such as:

• Basic: ordering food, asking directions, introducing yourself, getting through small talk. What most travelers actually need.

• Comfortable: keeping up in real conversations with friends, family, or coworkers, without translating every sentence in your head first.

• Native-like: jokes, nuance, debate, reading a novel. The highest bar, and honestly, most casual learners never need it.

Here’s roughly how many hours each stage takes for the languages Polyspeech covers:

Note: These are Polyspeech’s own estimates. We built them by scaling FSI’s difficulty rankings against general research on second-language proficiency. Real progress depends more on how effectively you practice than how many hours you log.

Polyspeech focuses on five languages: Spanish, French, Mandarin, Korean, and Japanese. Here’s what makes each one easier or harder to pick up, and where the early wins are:

Spanish

Spanish is about as close to English as it gets, and you’ll see results fast.

• What helps: Thousands of shared Latin roots with English (hospital, importante, familia). The grammar is pretty straightforward. Pronunciation is consistent, and words sound the way they’re spelled.

• Biggest challenge: Verb conjugations are tough. Spanish has more tense forms than English, and the irregular verbs take a while to sink in.

• Early win: You’ll be having simple conversations within weeks. That fast feedback loop makes it easier to stick with it.

French

French sits in the same easy tier as Spanish. The grammar’s similar, and the shared vocabulary with English is even bigger (around 30% of English words trace back to French).

• What helps: There is a huge vocabulary overlap with English. If you can read English, you can already recognize a lot of written French.

• Biggest challenge: Pronunciation. The spelling and sounds don’t line up the way they do in Spanish. Silent final consonants, nasal vowels, and that French “r” are hard to fix by reading alone.

• Early win: Reading comprehension comes fast thanks to the shared vocabulary. Speaking takes more work, but the grammar won’t slow you down.

Mandarin

In our experience teaching learners across all five languages, Mandarin is one of the toughest for English speakers, mostly down to tones and characters.

• What helps: The grammar’s actually simpler than most European languages (no conjugations, no gendered nouns, no plurals). The sentence order matches English too (subject-verb-object).

• Biggest challenge: The tones. There are four of them, including a neutral one, and the same syllable can mean totally different things depending on pitch. Then there’s the writing system, with thousands of characters to memorize for full literacy.

• Early win: You can hold real conversations in Mandarin long before you can read a newspaper. If you lead with speaking, that comes a lot sooner than people expect.

Korean

Korean shares Mandarin’s steep climb, but it’s got one big head start: the writing system.

• What helps: Hangul, the Korean alphabet, was designed in the 1400s specifically to be easy to learn. Just 24 basic letters, and most people can read it within a few days.

• Biggest challenge: Definitely grammar. Sentences run backward from English (subject-object-verb), and the honorific system means your word choice shifts depending on who you’re talking to.

• Early win: Once you’ve got Hangul down, you can sound out any Korean word, even before you know what it means. That alone makes everything else feel less intimidating.

Japanese

Japanese often tops the list of hardest languages for English speakers, and the writing system is the main reason why.

• What helps: There are no tones, so pronunciation is more forgiving than Mandarin. The grammar’s very different from English, but it’s regular and predictable once it clicks.

• Biggest challenge: Three writing systems stacked on top of each other (hiragana, katakana, and kanji), and functional literacy needs roughly 2,000 kanji.

• Early win: Spoken Japanese is much more approachable than the writing suggests. Lead with conversation, and you’ll be speaking well before you’re reading.

What Helps You Learn a Language Quickly

Try to log 300 hours on flashcards and multiple-choice quizzes, and you can still freeze up the first time someone actually talks to you.

Speaking practice fixes that.

One study found that learners who practiced by speaking beat the ones who only listened, not just at speaking, but at vocabulary, grammar, and listening comprehension too. Saying a sentence out loud forces your brain to do the work that just listening doesn’t.

Most apps skip this part entirely. In other apps, users match words, translate sentences, and tap multiple choice questions, and you never actually have to build a sentence and say it out loud.

Polyspeech is built around speaking. Our AI tutors listen, respond, and correct you in real time in Spanish, French, Mandarin, Korean, or Japanese, so every session is a conversation instead of a quiz.
