Training Line

TrainingLine is an NVDA add-on that provides a special line for practicing pronunciation and performing arithmetic simple operations.
It is particularly useful for learning, checking word pronunciation, and quick mathematical calculations.

Main Features

• Text pronunciation: Enter any text and hear its pronunciation
• Arithmetic calculations: Perform mathematical operations with various output options
• Flexible settings: Configure behavior when receiving calculation results
• Easy control: Simple interface with keyboard command support

Launching the Training Line

No keyboard shortcut is assigned by default.
To add a keyboard shortcut, go to Input Gestures, find the “Training Line” category, and assign a shortcut to “Open training line”.

Result Announcement Types

In NVDA settings (Category “Training Line"), you can choose one of four options for handling arithmetic results:

1. Speak result only - simply speaks the calculation result
2. Speak and copy to clipboard - speaks and copies the result
3. Speak and paste to line - speaks and pastes the result in “expression=result” format
4. Speak, copy and paste to line - performs all three actions

Configuration via NVDA Interface

1. Open NVDA menu → Preferences → Settings
2. Select “Training Line” category
3. Choose the desired result announcement type
4. Click “OK” to save
5. Press NVDA+Control+C to save settings to NVDA configuration

Audio Signals

The add-on uses various audio signals for feedback:

• Dialog opening: High tone (440 Hz)
• Focus received: Medium tone (330 Hz)
• Dialog closing: Low tone (220 Hz)
• Text boundaries: Short signals when reaching boundaries

Usage Tips

For Pronunciation Practice

• Enter words and phrases to check their pronunciation
• Use repeated Enter presses for multiple listening
• Practice complex words and sound combinations

For Mathematical Calculations

• Use different operator formats (×, *, х for multiplication)
• Decimal numbers can be entered with either dot or comma
• Results can be immediately copied to other applications

For Quick Work

• Memorize hotkeys for fast access
• Use Shift+Delete for quick field clearing
• Configure suitable output types for your tasks

Troubleshooting

Problem: Dialog doesn’t open

Solution: Check if there’s a conflicting input gesture. Try opening through NVDA menu.

Problem: Arithmetic expressions don’t calculate

Solution: Make sure the expression contains mathematical operators and is written correctly.

Problem: Copy to clipboard doesn’t work

Solution: Check the result type settings and clipboard access permissions.
