   Currently, STT functionality using flutter-tizen is not supported.
   While there are platform APIs available for STT(c++, c#), we have not yet found any use cases for them on TV devices.
   We explored the possibility of supporting STT functionality via a Flutter plugin, but ultimately could not complete the implementation due to various constraints associated with TVs.

   Hi @JSUYA ,

   Thanks for the update and for looking into this.
   Since STT isn't supported through flutter-tizen, I'd like to try building my own plugin. Could you help with two things?

   • Platform API access: Can you share the API documentation, samples or headers for the native STT API (C/C++ or C#)
   • Web app support: Does the Tizen web app runtime have an STT API?

   If you have an example of anyone getting STT working on a TV, even a partial one, that would help a lot. I'd also appreciate hearing about the constraints that stopped your Flutter plugin, so I can avoid the same dead ends.

   Thanks again

   Here is the API document.
   C++: https://samsungtizenos.com/docs/application/native/guides/text-input/stt
   C#: https://samsungtizenos.com/docs/application/dotnet/guides/uix/stt
   Web(Voice control): https://samsungtizenos.com/docs/application/web/api/10.0.0/tv/device_api/tv/tizen/voicecontrol
   Web(voiceinteraction): https://developer.samsung.com/smarttv/develop/api-references/samsung-product-api-references/voiceinteraction-api.html

   and refer here for the PR related to the STT plugin development.
   #1148
   (This PR is a PoC; it is not officially supported and is not planned for merging. Therefore, no technical support is guaranteed.)

   It looked as though the TV's Bixby was activating simultaneously when I pressed the recording button on the remote control.
   I am unsure whether this can be controlled at the 3rd-party dev level (e.g., Flutter-tizen plugin).
   and, i didn't tests using a separate microphone.(Security issues regarding the microphone or camera were not reviewed, and support for them is not confirmed.)
   As consistent behavior could not be guaranteed, I did not proceed any further.
