@Joinny,

in a previous post https://synthiam.com/Community/Questions/Inconsistent-Speed-Speech-Settings-after-Installing-Cepstral-18209 (#8) you asked the same question regarding Korean Language.

Your profile's country is Japan

now you mentioned you are a trainee in Vietnam.

Please be coherent ... otherwise it seems you are jumping around asking superfluous questions.

Azure Speech to Text:
https://docs.microsoft.com/en-us/azure/cognitive-services/speech-service/language-support

Languages supported (Speech Service):

will need to use Vietnamese speech recognition for the next 5 months science

It's clear Azure Speech to text does not support Vietnamese language. It's not a plugin issue or a community help.
If you are student you need to adapt your expectations to the existent technology, maybe there is a local company / university working on Vietnamese language, some local universities have government funds to develop local market solutions.

I quit useless time to create plugin for LUIS microsolf service?

I don't understand the question. Microsoft LUIS is a different product/API basically is a text language parser, it works with text inputs (strings) extracts intentions and entities.

Microsoft Luis supported languages:
https://docs.microsoft.com/en-us/azure/cognitive-services/luis/luis-language-support



Vietnamese is not supported BUT:

Quote:

If you need to provide language understanding for a language LUIS does not support, you can use Microsoft Translator API to translate the utterance into a supported language, submit the utterance to the LUIS endpoint, and receive the resulting scores.

Language and region support for the Translator Text API:
https://docs.microsoft.com/en-us/azure/cognitive-services/translator/language-support
 



It seems there are some (not full) support for Vietnamese you will need to test the existent support and adapt your expectations.


You can submit text sentences to the Microsoft Translator API and then pipe the results to the Microsoft LUIS and then trigger your actions. 

The above workflow/solution works with text.

Developing a plugin does not solve all the tests and above issues and if you need (want) to interface with EZ-Builder there are other available methods: Http Server, Read & Write from a file on the disk (EZ-Script), Javascript plugin.

Sorry, I may have mistaken for you but I'm from Japan and I'm working in Vietnam because my father is Vietnamese. Thanks again for the answer, I will try it and if there is any question, please help me

I also emphasized that I have the espeak-vi package download and use Azure speech service and basically still speak even though it is still buggy. And I think it's difficult for me when I don't know the specific to work with Vietnamese but if you think that is an unnecessary question and think it easy, please help me.
I just don't know, I need to learn. It's sad when you say that!!!!!!

Asfaik espeak is a Speech synthesis i.e. converts text to Speech. Speech Recognition is the opposite converts Speech to Text.

If you are looking Vietnamese Text to speech  windows 10 supports (similar answer to your question regarding Korean support):



You can install the Vietnamese language support, and use EZ-Builder Speech synthesis control, and i believe it works much better than the espeak package. 

As i mentioned before (Korean post) windows support (above add-on) can't be used for Speech to text.

So are you trying to find a solution for Speech to text or Text to speech ?
