Is there a way to fix the issue with andriod build. @ShaneC is there a way i can add the path to com.sphinxue4.SpeechRecognitionWorker in xml ? this fails when i change the andriod version and ndk version. i was able to build this earlier but it failed because it can’t find the path. ```auto ndroid (ASTC)): > Task :app:processDebugResources UATHelper: Packaging (Android (ASTC)): > Task :downloader_library:generateDebugBuildConfig UP-TO-DATE UATHelper: Packaging (Android (ASTC)): > Task :downloader_library:javaPreCompileDebug UP-TO-DATE UATHelper: Packaging (Android (ASTC)): > Task :downloader_library:compileDebugJavaWithJavac UP-TO-DATE UATHelper: Packaging (Android (ASTC)): > Task :downloader_library:bundleLibCompileToJarDebug UP-TO-DATE UATHelper: Packaging (Android (ASTC)): > Task :permission_library:generateDebugBuildConfig UP-TO-DATE UATHelper: Packaging (Android (ASTC)): > Task :permission_library:javaPreCompileDebug UP-TO-DATE UATHelper: Packaging (Android (ASTC)): > Task :permission_library:compileDebugJavaWithJavac UP-TO-DATE UATHelper: Packaging (Android (ASTC)): > Task :permission_library:bundleLibCompileToJarDebug UP-TO-DATE UATHelper: Packaging (Android (ASTC)): > Task :app:compileDebugJavaWithJavac FAILED UATHelper: Packaging (Android (ASTC)): The following annotation processors are not incremental: lifecycle-compiler-2.0.0.jar (androidx.lifecycle:lifecycle-compiler:2.0.0).

Hello, First, thank you for your work. I also have a question about this plugin. I follow your instruction but it’s still doesn’t work for me ![Capture1](https://d3kjluh73b9h9o.cloudfront.net/original/4X/1/7/a/17a1c84ee51e2111038de489f2e7f281c5cd6e83.png) I retrrieved the model folder (from the sample project) and put it in the content folder. I’m still missing something I think 🙂 Is there any prerequisite that is needed (dev tool or so )? Thank you ---

I notice it was asked above but not sure if anyone has an answer for it. I am also trying to use this with the VOIP features but it just wont. Is there something beyond the scope of this tutorial I am missing? ---

Hello I guess you got too busy back then to come back, but I would still really appreciate the help. I want to have a simple voice recognition Turbolift in my Enterprise D… I would really appreciate if you could help me find a copy of the Pocket Sphinx Demo Scene (with the soccer game) that would run in 4…27 (and maybe the Android to since that would be a cool thing!) I have tried for many many years to get this to work and still I trty ,. Please.! I will share my extensive tool and assets!! 🙂 Thank you. ---

Hey @ShaneC , i don’t even know If you still have access to your account or not since its been forever lol. I just wanted to first of all thank you for this plugin and I wanted to inform you that I needed your plugin for a big university project as a final capstone one and fortunately I have managed to make a modernization of it and a scalable adaptation to the UE5 version. I have sent you a friend request on epic games. I just want to show u my approach and a possibility to add my solution to the github main code it will benefit my academic achievement and any user who wants to use your life-saving plugin for the newer versions. Hopefully you are still on the platform and I’m waiting for your reply to discuss further details in private before releasing it to the public.
