Problem with uploading building to Somnium Space throw Unity

I encountered a problem when loading a 3D model of a building in the Somnium Space metaverse. The model meets all requirements.

I followed a tutorial to use text to speech with IBM Watson Assistant in Unity 2019.4.9f1. The problem is doesn't translated the text into speech, I did a few logging to see if it received the result from Assistant and it did but it's not turning into speech. I'm new to working with Unity and IBM Watson so I don't understand what's the problem. I tried looking up the error online but I can't find any solution to it. Any help would be greatly appreciated.

If you have fixed/ non changing lines you want to be translated into speech the best thing to do is to make them into an audio file and then import them into unity.
what you could also do is do the speech yourself and import it.
this is also helpful because then you can trigger the audio on a collision with other objects/points. for example in a tutorial level.
the other solution is to check your console i see 3 Errors and the rest just looks like warnings if you fix the errors the warnings will go away.
the first one looks like you have a bad request to the server, try another sml tag and check if it works.
the second and third one is the buffer, that should be configured in the code. so if you fix that you fix all the problems!

Before, I can see some options so that I can try to build.

I was having this issue as well. Nothing worked until I did this:
Go Unity > Preferences, select External Tools, deselect everything
Close the Editor
Open the Editor, re-enable everything you deselected
Hit Play to force a refresh
Then build again and it'll work

I got the same error and fixed it in a different way.
Possible fix here Failed to update Android SDK Package List

I got the same error after importing the firebase SDK into Unity 2021.3.3f1. It turned out my system variable JAVA_HOME was not pointing to the Java used by Unity (which apparantly only caused a problem in combination with firebase).
To solve it I had to
change Windows 10 -> Settings -> System -> Edit System variables
Change the value of "JAVA_HOME" to my Unity Java version: "F:\Programs\Unity\2021.3.3f1\Editor\Data\PlaybackEngines\AndroidPlayer\OpenJDK"
Reboot my Computer (for the JAVA_HOME change to take effect)
In Unity: Click on Assets -> External Dependency Manager -> Android -> Resolve
Not sure if the last step was necessary. I tried a lot of things (including "regenerating project files" - from Unitys settings)

Unity Watson SDK error on Speech to Text Example

I'm trying to run the newest Unity Watson SDK from GitHub. Whenever I try to play the example scene for speech to text, I get this error. I have the API key set and my region is US-Dallas, but I don't think it's related to the problem.
I'm building an app for Android that utilizes speech to text. I've tried looking this up for hours, but I can't find a solution. I've tried re-downloading the SDK but nothing changed.

The native side of the code required to generate text is not available on Linux yet. The plugin itself should work during run-time in a build but its Editor tool is not supported on Linux. The Editor tool is only supported on Windows and Mac.
The original reason for the lack of support is because only few people use Linux when enveloping games with Unity. Also Unity Editor itself does not support Linux officially. Whatever support they have for it is still in experimental mode and there are many issues that makes it not worth using at this point.
Since TextMesh Pro is now bought by Unity, it's very likely that Linux will be supported. You should wait until Unity finally integrate it with Unity and maybe they will add support for Linux. At this moment, I think you should file for a bug report to remind Unity that this issue is still there then just use the Text component until they fix it. If you still want to use TextMesh Pro, a workaround is to use VMware Workstation to run Windows or MacOS on your Linux then you can use them to create the Text Assets and export and import them as Packages in your Linux project.
