How can i use the streams APIs to generate speech-to-text using actor?

Hello d-id,

I wan to achieve speech-to-text to convert my text to specific answer and this answer should play using actor. I want to achieve this functionality using talks/streams in android mobile app. How can i achieve this in android to show character which speaking words which i have sent?

I want to achieve this using streams APIs only.

I see a demo which was using a node js but this not works for me.
