No speech detected

[ghost]

I have 1 master and 1 worker up and running using https://github.com/jcsilva/docker-kaldi-gstreamer-server. I have also configured a Node.js client using your dictate.js. The client server is very simple and I only had to change the path pointing to the worker.

I changed the following in dictate.js

var SERVER = "ws://localhost:8080/client/ws/speech";
var SERVER_STATUS = "ws://localhost:8080/client/ws/status";
var REFERENCE_HANDLER = "ws://localhost:8080/client/dynamic/reference";

and in my home page I've added

option(value='ws://localhost:8080/client/ws/speech|ws://localhost:8080/client/ws/status', selected='selected') localhost

However I am unable to send data from the client to the worker. This is my worker log. The app log does not offer anything for me to debug, and I can't get much information out of the worker log either.

Worker log:

The out-dir is where audio is received, it is pointed to tmp in the Docker container. Inside tmp, the only content is pip_build_root and no audio files. I know my client side audio configuration is working because the mob demo works fine. Therefore the issue must be the connection between my Node server and the Kaldi server.

Did I miss something? Thanks
