Error Running On Raspberry Pi Runnig Ubuntu MATE

[efraimnewman]

Describe the bug
I am trying to use intent recognition on raspberry pi running ubuntu mate (32 bit), using c# and .net core.
when I run the app I get this 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)

other apps that use the microphone are working fine

To Reproduce
I used a fresh installation of ubuntu MATE for RPi. I am using a webCam as a microphone.

Version of the Cognitive Services Speech SDK
I am using version 1.11 which is supposed to support linux-arm.

I already opened this issue over here, but I was asked to reopen on this repo

@efraimnewman Seems that the keyword model file you give to Microsoft.CognitiveServices.Speech.KeywordRecognitionModel.FromFile(String fileName) is failing as file is not found. Do you provide absolute path to file ?

Thank you that worked. I also needed to use the fix mentioned here but now I have different error:

mmap() failed: Cannot allocate memory
Failed to create permanent mapping for memfd region with ID = 3597799991
Failed to regester memfd mempool. Reason: could not attach memfd SHM ID to pipe
mmap() failed: Cannot allocate memory
Failed to create permanent mapping for memfd region with ID = 710812132
mmap() failed: Cannot allocate memory

Ignoring received block reference with non-registered memfd ID = 269852665
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Protocol error

can this be caused by the Text To Speech that I am using or is it something else?
although the app is still working fine after this error.

I see that I am only getting this error sometimes but the app works normally. I can say this issue is solved. Thank you so much
