Drag the A slider to just before the phrase, the B slider to just after. Set speed to 0.75x if it's fast.
Let the loop run. Absorb the rhythm and melody of the phrase before you try to speak.

When you're confident at 0.75x, bump it to normal speed and verify your pronunciation.
About using InfiniteLooper for language learning
Yes. Set the A point just before the phrase starts and B just after it ends. InfiniteLooper will repeat that exact sentence as many times as you need — ideal for pronunciation drilling and shadowing practice.
InfiniteLooper works with any language available on YouTube. It's especially popular for Spanish, French, Japanese, Korean, Mandarin, Portuguese, and German learners, where native speed is often challenging for beginners.
InfiniteLooper goes down to 0.25x (quarter speed). This is slow enough to catch individual sounds in fast-spoken French liaisons, Japanese pitch accent, or rapid Spanish contractions. Most learners use 0.5x–0.75x for comfortable comprehension practice.
Yes. InfiniteLooper has a built-in notes panel that opens alongside the video. Write vocabulary, translations, or grammar notes while the video loops — no tab switching, no losing your place. Create a free account to sync notes across devices.
Yes. AB loop, 0.25x–2x speed control, and video notes are completely free with no account needed. A premium plan ($1.99/month) adds unlimited saved loops and tag organization — useful for organizing loops by language or topic.
