I'm using Bixby Developer studio and I have my UI output created and it works. How do I create or control speech output?
Bixby will automatically read the text in the UI - if that is sufficient, you are set. (Be careful here - In good VUX design, UI text and speech text are typically different. UI text is often longer, speech text often shorter and more expressive).
To have speech different from the UI text, you should set the speech key of a template in a dialog. You can use all of the features of dialog like Bixby EL language here.
Update: Bixby now supports SSML
