Confirming Successful Deployment of V‑Blaze

The final steps in a V‑Blaze deployment are to restart the service and confirm that it is working. The following command will start the ASR engine service:

sudo service vociserver restart

There are multiple ways to confirm that a V‑Blaze instance is running:

  1. Check the err.log file using the following command:

    cat /var/log/vociserver/err.log
    

    The contents of the file should be similar to the following:

    2020-07-24 17:53:46.809137 initializing
    2020-07-24 17:58:10.457873 serving on port 17170
    
  2. Query the status of V‑Blaze with a V‑Blaze API request:

    curl https://vblaze_name:17171/sysinfo
    

    The response should be similar to the following:

    {   
        "sysinfo": {
           "aminfo": {
            "eng1-acoustic31": "3x GPU, 0.99 GiB",

        "version": "7.2.0-0",
        "webapi": "2.2.0-0"
        }
    }
    

    Refer to API Endpoints for detailed information on V‑Blaze API queries.

  3. Transcribe an audio file with a V‑Blaze API request:

    curl -F output=text -F file=@/opt/voci/server/examples/sample1.wav http://localhost:17171/transcribe
    

    V‑Blaze should return a transcript of sample1.wav in plain text:
