WordBridge is an NVDA addon that helps users identify and correct homophone-based typos in Chinese.
In addition to identifying and correcting homophone typos, WordBridge generates detailed reports that list the original typos, suggested corrections, and detailed descriptions of each character. This helps users learn from their mistakes and gradually master correct usage, effectively improving both language proficiency and typing accuracy.
To check text for typos, select the desired content and press NVDA+Alt+O. A sound effect will play during the check. Once complete, the corrected text will be automatically copied to the clipboard for further use.
Each time a check is performed, WordBridge generates a web-based report that clearly lists all identified typos. Each typo appears as a clickable button—clicking it reveals detailed descriptions of both the incorrect and corrected characters, helping users better understand proper usage.
If the “Automatically Show Correction Report” option is enabled, the report page will open automatically after each check. Otherwise, you can open it manually at any time by pressing NVDA+Alt+R.
You can configure WordBridge via NVDA Menu → Preferences → Settings → WordBridge. The available settings include:
Service Provider
Select the cloud computing provider that powers the correction service.
Large Language Model (LLM)
Choose an appropriate language model based on the selected provider.
Correction Mode
Lightweight Mode: May produce corrections that differ more from the original pronunciation, suitable for input contexts where users want to explore broader homophone associations.
Simplified/Traditional Chinese
Specify whether the language model should process Simplified or Traditional Chinese. Input text will be automatically converted to match the selected form.
Personal Dictionary
Provide a custom vocabulary list to improve correction accuracy for domain-specific or specialized terminology.
