I want to display a text paragraph(in black color) and a “PLAY” button. When the user clicks on “PLAY” button, it should start speaking(TTS) the text sentence by sentence alongside it should change the spoken text color to green (character by character)
Any suggestions appreciated… 🙂
You can use a TextSwitcher
See these tutorials / examples. They will help you get started:
And finally, I believe an example is also available in the API demos from the Samples For SDK (API 13 I think) package in the SDK Manager
You will naturally have to code for synchronizing the TTS speech and the animation itself.
