Number Auditory

🌐 Try it online: https://numbers.snownamida.top/

A free, multilingual number-dictation trainer for language learners: it generates a random number, reads it aloud in your target language, you type what you heard, and it scores you instantly. Numbers — prices, years, phone numbers, quantities — are one of the things most likely to trip you up in a foreign language, and focused, high-frequency drilling noticeably speeds up your reactions. No signup, no API key — everything runs locally in your browser.

✨ Features

• 🌍 Any language: automatically lists every speech language installed in your browser / system (Spanish, French, English, German and Japanese also get a spoken "here comes the number" lead-in phrase); you can pick a specific voice
• 🎯 Range presets: 0–100, 0–1000, big numbers (millions), years 1900–2100, prices (with decimals), or a fully custom range
• 🏆 Scoring & streaks: correct count, total count and best streak, saved locally (localStorage)
• 🎚 Adjustable speed / pitch, with "replay" and "next" available at any time
• 🇪🇸 For Spanish, the answer also shows the written-out form of the number (e.g. 142 → ciento cuarenta y dos)
• 📱 Works on phone, tablet and desktop; the decimal separator is accepted as either . or ,
• 🔒 No online TTS, no API key required: speech uses the browser's built-in Web Speech API (speechSynthesis) — free and privacy-friendly

🚀 Usage

1. Open https://numbers.snownamida.top/
2. Choose a language and number range, then click "🔊 Play"
3. Type the number you heard into the text box and press Enter or "Submit"
4. Pressing Enter with an empty box = replay the current number

💡 No sound? Click "Play" once first (browsers require a user interaction before they can speak), and make sure your system has the voice pack for that language installed.
