Hi xharrix,
Thanks for posting in the community!
I understand how inconvenient it is that the official Vietnamese language isn't supported yet on Google Home speakers. We appreciate your interest in using the device in your preferred language. Adding new languages to our products is a complex process that involves careful consideration of various factors.
I understand that this is a helpful language that makes your experience easier through the Google ecosystem, and we all hope to make it available on Google Home speakers in the future.
In the meantime, I deeply appreciate you sharing your feedback to continue improving our products and meeting your needs.
Additionally, you can check out this article to get more information about the country and supported languages: Learn about devices & services available in your region.
Let me know if you have more questions.
Best regards,
Jenniffer
