Azure Speech SDK Intent recognition Error on Ubuntu MATE ARM32

I am trying to do basic intent recognition using the Speech SDK on Ubuntu MATE ARM32 (on a Raspberry Pi). The docs say the version 1.11 should work but I am getting the following error:

Unhandled exception. System.ApplicationException: Exception with an error code: 0x8 (SPXERR_FILE_OPEN_FAILED)
   at Microsoft.CognitiveServices.Speech.Internal.SpxExceptionThrower.ThrowIfFail(IntPtr hr)
   at Microsoft.CognitiveServices.Speech.KeywordRecognitionModel.FromFile(String fileName)

   at SmartHomeVoice.Program.Main() in E:\Efraim's stuff\SmartHomeVoice\SmartHomeVoice\Program.cs:line 19

I am using C# and .Net Core 3.1, and I have a webcam plugged into the Pi which I set to be the default audio input through the GUI. Ubuntu version is 18.04.

Solution

This issue was solved here. The problem was that I didn't supply an absolute path for the keyword table file.
