I would like to create a websocket client for the Custom Speech service using a programming language such as Java, NodeJs, Go. Where can I find some technical information on how to consume that websocket from scratch (the expected message, fields, etc)?. I already read the CSS documentation but it focuses on how to use the SDK libraries for C#, javaScript, Android. What should I take into account if wanted to create my own SDK for a different language?
Thanks in advance.
