What it is
Number Trainer helps you learn and practice spoken numbers from 1 to 1,000,000 in fourteen languages. You hear a number, then type what you heard — the same skill you need for prices, phone numbers, and everyday listening.
How it works
- Learn — browse a level, hear each number, unlock the next level when finished.
- Practice — random drills with optional filters and spaced repetition toward weaker numbers.
- Your language — UI labels in the language you speak.
- Practice language — audio and number words in the language you are learning.
Speech (TTS)
Audio is generated on demand using Microsoft Edge neural text-to-speech
via the open-source edge-tts-universal library. This is an
unofficial integration — not endorsed by Microsoft and offered
without a production SLA. Service may change, rate-limit, or fail without notice.
Version
Number Trainer 1.0.0
Platforms
Works in the browser and as Android / iOS apps (Capacitor). Mobile apps need a
running API server for speech — see Help and
DEPLOY.md in the project repo.
