About

Tempo Spanish

Features

Speak Spanish like a Spanish-Speaker. Tempo turns real YouTube videos into bite-sized speaking practice. Listen to a segment, repeat it out loud, and get instant feedback on what you nailed — and what you didn't. No streaks to guilt-trip you. No cartoon owls. Just real video, real speakers, and the kind of repetition that makes you actually fluent. — REAL CONTENT — Browse curated Spanish-language channels by topic, difficulty, and duration. Stories, history, comedy, vlogs — pick what interests you and start practicing. — SHADOW SPEAKING — Tempo plays each segment, then hands the mic to you. Speak along, submit your take, and move on. Your mouth learns the shape of the language. — INSTANT FEEDBACK — Word-level accuracy scoring after every attempt. See exactly which words you missed, swapped, or mumbled, and replay your own recording to compare against the target. — ADAPTIVE DIFFICULTY — A hint slider lets you mask words on the transcript — from a gentle nudge to full memorization. Tempo auto-adjusts to each channel so it's always just hard enough. — VOICE CONTROL — Hands-free practice. Say "next", "repeat", "slower", or "record" to drive the app without touching the screen — practice on walks, hikes, or your commute.
