Tizen Forums

For Tizen App development you have to choose a platform suitable for you:

-Native App (C/C++)

- Web App (HTML,CSS,JS)

-.NET App (C#)

For Tizen.NET there's a Sample Application available : SpeechToText

The Sample code is for 'Mobile' platform, But even if you are targeting for 'Wearable' the code base/API is exactly the same. For Tizen Wearable you can reuse the code base from sample application.

And If you are interested in Native (C/C++) platform in that case, though I haven't found any Sample application but there's a complete guide on 'Speech to text' with code examples, You can follow that.
