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.
