##Implementing Communication with Bluemix STT Engine
This socket establishes communication with IBM Bluemix Watson's Speech-to-text engine via WebSocket-Sharp (WebSocket realized in C#) in Unity, which generally provides the user interface, as well as further possibilities for integrating this socket into other applications.
Note: My initial purpose for writing this socket was to use it in a VR Marionette project established by the Intersections Digital Studio of Emily Carr University of Art + Design, where meanwhile I was doing a Globalink© Research internship funded under Mitacs© and China Scholarship Council. Later the socket was rewritten via Max Cycling-74 (source code on GitHub in a much more efficient way.
Note: Languange preference for STT conversion in the socket: English (default).
####Implementations:
-
A C# implementation of the WebSocket protocol client and server
[WebSocket-Sharp](https://github.com/sta/websocket-sharp): -
A widely used JSON framework for .NET by Newtonsoft, used for parsing Json responses from Bluemix
[Json.Net](https://github.com/JamesNK/Newtonsoft.Json): -
3rd party script for saving audioclip as .wav files

####Instructions NOTICE :To successfully establish communication with Bluemix STT, you'll need to have an account for Bluemix console and create an instance for STT, which assigns a credential username and password, and you'll need to use that for this socket
- Download the complete repository
- Fill your credentials obtained from Bluemix STT instance in line 58 and 59 of Assets/Socket.cs
- Start the Assets/mic.unity scene
- Press "Record" and speak to the microphone
- Press "Stop" when finish
- Press "Save", which saves the recorded audio in D:\STT, and then communicates with Watson to get the result
- The result will be shown in the log of Unity, as well as written to D:\STT\rcv.txt
