Submit a Bug Report via Microsoft 365 Feedback

Since this spacing behavior is a known limitation in the current version of Word Dictate, reporting it directly to the product team is the best way to prioritize an official fix.

Thai language relies on continuous script without spaces between words. The dictation engine currently struggles with these word boundaries. Submitting direct feedback provides Microsoft with the diagnostic data needed to refine their Thai language models.

Launch Microsoft Word on your desktop, navigate to the top ribbon, and click on the 'Help' tab.

2
Access the Feedback Tool

Frequently Asked Questions

Why does Word Dictate add spaces between Thai words?

The Thai language is written in a continuous script without spaces between words. The Microsoft dictation engine currently struggles to accurately identify word boundaries in Thai, resulting in the system incorrectly inserting spaces as it does for Western languages.

Does this spacing issue affect other Microsoft 365 applications?

Yes. Because the dictation engine is a shared cloud service across the Microsoft 365 ecosystem, you will likely experience the same Thai language spacing issues when using the dictation features in PowerPoint, Outlook, and OneNote.

Can I fix the Thai dictation spacing by changing my Windows language settings?

No. The issue stems from Microsoft's backend voice recognition algorithms rather than local Windows language packs. Changing your keyboard or regional settings will not resolve the dictation spacing behavior.
