The use of English keywords with holographic remoting and keyword recognition functions smoothly.
However, when I attempt to use non-English keywords (e.g., Chinese), an error occurs while adding commands to the remote speech profile. This leads me to wonder if there are additional steps required to enable non-English speech input. The error displayed is as follows:
[XR] [MROpenXR][Error ][10:40:43.984083][tid:a6a8] openxr_plugin_SetXrSession_StdException Function=openxr_plugin_SetXrSession Message=string too long
[XR] [MROpenXR][Error ][10:40:43.984083][tid:a6a8] openxr_plugin_SetXrSession_StdException Function=openxr_plugin_SetXrSession Message=string too long
Additionally, under normal circumstances, the RemoteSpeechProvider initializes the keyword dictionary as shown below. However, this initialization does not occur when I use a Chinese keyword.

Hello, Welcome to Microsoft Q&A,
Hi, are you planning to use non-English voice commands on the HoloLens2? I’ve tested non-English voice commands using Holographic Remoting and while deploying to the HoloLens, but I can’t reproduce your issue. Can you provide more information about your operations?
And what’s the display language on your device? The HoloLens2 does support voice commands in several languages including Chinese. However, according to my tests, non-English commands will not function on an English version of the HoloLens device. To use non-English voice commands, you need to set your desired language as the display language on the HoloLens and then restart your HoloLens device. The language model for speech is based on the selected UI language and its dictionary is built on real words for that language, so the recognizer will not recognize foreign words without first switching the UI language to the appropriate native language.
If you are using Holographic Remoting, you might want to consider changing the language settings on both your PC and HoloLens to your desired language.

Hi,
I have already updated the language settings on my PC and Hololens to my preferred language, yet the error persists. I utilized the SpeechInputExample and modified the Speech Input keywords accordingly. If you need any additional information, please feel free to ask.
Additionally, a runtime error shows up when I test with holographic remoting with non-english keywords in Unity Editor.

Hi @WL.TSAI ,
Have you tried to use Holographic Remoting under the Play Mode in the Unity Editor? If so, did the error persist? To use Holographic Remoting for play mode, you can simply navigate to Mixed Reality -> Remoting -> Holographic Remoting for Play Mode.
To resolve the runtime error, please navigate to Edit -> Project Settings -> XR Plug-in Management and ensure that the “Holographic Remoting remote app feature group” is selected.
Hi
Thank you! Following your selection, I chose the ‘Holographic Remoting remote app feature group’, and the runtime error no longer appears.
However, I’m still unable to use non-English words in the SpeechInputExample, as an error is displayed in the Editor.log.

Hi @WL.TSAI , I did some tests again. The conclusion drawn is that the deployed application on the HoloLens operates non-English voice command successfully when the HoloLens display language is set to my target language. However, an error similar to yours appeared when using Holographic Remoting. I plan to discuss this issue with my team. If your goal is to test a non-English voice command, I recommend deploying your application to the HoloLens2. I noticed that you’re using LocalizationKey, which is used in UWP apps. Therefore, if you’re running the application in the Unity Editor using Holographic Remoting, it won’t function.
Hi @Ying Li - MSFT Thank you for the reply. For our team’s application, we still hope to use non-English voice commands under Holographic remoting. Currently, we will prioritize Holographic remoting with English voice commands, looking forward to other follow-ups. If there are any updates or if there’s anything I can help with, please let me know.
