Translate real sentences into Spanish, hear each one in a natural voice, then go deeper with grammar guides, 1000 key words, travel phrases & stories.
Sentence Lab helps you build real Spanish fluency by practicing complete sentences, not just flashcards.
HOW IT WORKS
• See an English sentence
• Type the Spanish translation
• Get instant feedback
• Learn from your mistakes with helpful explanations
SMART LEARNING

content is spaced out for efficient long-term retention.

This update makes Sentence Lab more helpful, more guided, and a lot more fun to come back to.
• Natural Spanish voices — exercises and stories are now read aloud in a real, human-sounding voice that matches your accent (Latin American or Castilian) and your chosen voice.
Pick female or male in Settings.
• Guided Conversations (Scenarios) — practice real dialogs turn by turn: order at a restaurant, check into a hotel, meet someone new. Listen to each line, then build your reply.
(Premium)
• Reading comprehension — stories now end with a quick comprehension check so you can test what you understood.
• Travel flashcards — study essential travel phrases with new flashcard and test modes.
• A friendlier home base — a warmer welcome, a new guide for getting started, and a little encouragement along the way.
Plus a refreshed practice screen and lots of polish throughout. ¡Vamos!
