I have built a web based Speech-to-Text application with Google 
Speech-to-Text API.

The application flow:

   1. Get audio stream from browser 
   2. Stream audio data to a speech recognition service and get real time 
   results as our user talks

I have referenced the sample code 
<https://github.com/googleapis/nodejs-speech> in my application, the 
streamingRecognize request works perfectly with a signal client call, and 
my server can receive the interim-transcription result from Google Speech 
API. However, when there are more then one client call streamingRecognize 
simultaneously, 
Google Speech API will get stuck. So, may I know how to handle more than 
one streamingRecognize request concurrently? Do I need to create another 
client to process the second streamingRecognize request? Thanks.
   
Back-end server specifications:

   - NodeJS
   - Socket.io
