Accuracy, mistakes, streaks, session time, and character-level performance are tracked during practice.
ECHO is designed to provide a complete blind typing practice environment for both letters and numbers.
The system combines:
Voice Guidance + Keyboard Practice + Smart Repetition + Performance Analytics
to help users improve their typing accuracy, character recognition, and confidence while typing without constantly looking at the screen.
ECHO is a Blind Alphabet Trainer built to make alphabet typing practice more engaging through voice-based interaction.
Instead of simply displaying a letter and asking the user to type it, ECHO creates a practice environment where users can:
- 🎙️ Hear the target letter
- ⌨️ Type the corresponding key
- ⚡ Receive instant feedback
- 📊 Monitor accuracy
- 🔥 Build typing streaks
- 🧠 Identify weak characters
- 💾 Save practice sessions
- 📁 Export performance data
ECHO covers the complete English alphabet:
A B C D E F G
H I J K L M N
O P Q R S T U
V W X Y Z
Each character can be individually tracked to help identify which letters require more practice.
ECHO uses voice feedback to make typing practice more interactive.
The system can:
- 🔊 Pronounce the target character
- 🔁 Repeat the pronunciation when requested
- ⚡ Move to the next character after correct input
- 🎧 Provide an audio-based learning experience
This makes ECHO particularly useful for users who want to practice without constantly looking at the screen.
ECHO continuously tracks the user's performance during a practice session.
- ✅ Correct attempts
- ❌ Incorrect attempts
- 🎯 Accuracy percentage
- 🔥 Current streak
- 🏆 Best streak
- 🧠 Weak characters
- ⏱️ Session duration
- 📊 Character-by-character performance
One of ECHO's key features is its character-level performance tracking.
Instead of showing only an overall score, the system can analyze individual letters and identify characters where the user makes more mistakes.

This helps users understand which letters need additional practice.
ECHO provides session management features that allow users to preserve and review their practice activity.
- 💾 Save Session
- 📁 Export CSV
- ⏱️ Session Time Tracking
- 📊 Performance Records
The CSV export feature makes it possible to take practice data outside the application for further analysis.
ECHO includes simple controls for managing a practice session:
| Control | Purpose |
|---|---|
| Begin a typing session | |
| ⏸️ Pause | Temporarily pause practice |
| 🔊 Repeat | Repeat the current letter |
| ⏹️ Stop | End the current session |
| 💾 Save Session | Store session performance |
