Hello Rickymahk2013,

It's great to hear that you're exploring multilingual capabilities for your EZ-B v4 robot using ARC. Let's address the issue you're encountering with Cantonese language support in the Speech Recognition system.

Based on the steps you've taken and the information provided, it seems like you've already made sure to follow the Speech Recognition Tutorials and attempted to change the language settings. Here are a few additional steps and considerations that might help resolve the issue:

1. Check Language Pack Installation: Ensure that the Cantonese language pack is installed on your Windows operating system. Language packs can be added through the Windows Settings under "Time & Language" > "Language" > "Add a language."

2. Verify Language Support: Not all languages may be supported by the default Windows Speech Recognition system. If Cantonese is not listed as an option in the Speech Recognition settings, it may indicate that it's not supported or the language pack is not correctly installed.

3. Update ARC: Make sure you are using the latest version of ARC, as updates may include fixes or improvements related to language support.

4. Bing Speech Recognition: Since you mentioned that Bing Speech Recognition works with Cantonese, consider using Bing Speech Recognition as an alternative to the default Windows Speech Recognition within ARC. You can use the ControlCommand() function to interact with the Bing Speech Recognition skill from your scripts.

5. Check ARC Skill Compatibility: Verify that the ARC skills you are using, such as Watson Text To Speech and Darknet YOLO(Obj Detection), are compatible with the language you are trying to use. Some skills may have limitations on the languages they support.

6. Consult ARC Support: If the issue persists, consider reaching out to the ARC community forum or support area for assistance. Other users or the support team may have encountered similar issues and can provide guidance.

7. Language Configuration in ARC: Double-check the language configuration within ARC's Speech Recognition settings to ensure that Cantonese is selected and configured correctly.

8. Test with a Simple Phrase: Start with simple phrases that are known to work in Cantonese with Bing Speech Recognition. This can help isolate whether the issue is with specific phrases or the language setup in general.

Remember that language support can vary between different speech recognition services, and not all services may support Cantonese. If Cantonese is crucial for your project and you cannot get it to work with the default Speech Recognition system, using Bing Speech Recognition or another third-party service that supports Cantonese may be the best solution.

If you have any further questions or need additional assistance, feel free to ask. Good luck with your multilingual robot project!
