c# Error: System.AccessViolationException Message=Attempted to read or write protected memory.

[rkmoray]

I am using you example for C# in .net 6 (I already tried core 3.1)

[nshmyrev]

Probably there was an earlier error, model should be null.

Please check the output for messages.

[rkmoray]

Since I get the error on initialing the object and model has been initiated as well, this is the only error I get

[nshmyrev]

Handle is 0x0 which means there was an error on model initialization. Most likely path to the model is wrong in model constructor. Simply read the standard output of the program, it contains the reason.

I have the same problem

I don't get why this isn't working! "VoskAPI" I don't know where the file is nor do I know where "model" file path is or where to redirect it too. Most open source I download works like it's suppose to, I don't get why this isn't working. I'm using VS2017 and VS2019, I install Vosk 3.31 or updated to 3.32 and still getting the same error

[nshmyrev]

@Skywalker200 the message says you need to specify a path to the model folder in Model constructor. It suggests you to specify an absolute path to the model.

[Skywalker200]

thanks for reply! As I said below the pic, I don't know where "VoskAPI" is, nor do I know what the path for "model" is nor to were to redirect it too.

Found the solution, man, why didn't the writer of this program write this in the README.md file.

For everyone else that gets this problem, they fail to mention. You half to download the model from here, https://alphacephei.com/vosk/models The nuget that is provided with the download doesn't seem to work. After you downloaded "vosk-model-en-us-0.22-lgraph" or what ever version you downloaded. Unzip it, you will get this folder ""vosk-model-en-us-0.22-lgraph" when you double click on it, you see the same folder name "vosk-model-en-us-0.22-lgraph", this what you copy and past into "vosk-api-master\vosk-api-master\csharp\demo\bin\Debug" and change the name to "model", now this part is fix. Now if you go back to "vosk-api-master" folder, then search for the "test.wav" file. Once you find it, copy and past "vosk-api-master\vosk-api-master\csharp\demo\bin\Debug".

Now, all should be good, you will notice the program start and finish, the writer fail to enter Console.Read(); line after Console.WriteLine(rec.FinalResult()); and now you should be good to go.

I just don't get why they couldn't added this to the README.md, all of this could of been avoided.

Anyways, problem solved, Cheers!

Thanks for the answer. I just wanted to try this out and had no idea. Beside README.md it would be better, if there was an appropriate error message.
