Windows supports Bengali input for Bengali (India), but the provided information does not show an installable speech recognition tool for Bangla/Bengali (India).
What is available:
- In Settings > Time & language > Language & region, add Bengali (India).
- This adds Bengali typing support.
- To type in Bengali script, open Language options for Bengali (India) and add the Bangla Phonetic keyboard if needed.
- This does not require changing the Windows display language.
For Microsoft 365, a Bangla (Bengali India) language accessory pack is available, but it provides partial localization and proofing tools, not a Windows Bengali speech recognition tool.
There is also community feedback requesting Bengali voice dictation, which indicates this capability is being requested by users.
