I have been trying to use Google Speech-to-text v2 in node.js to recognize streaming input. For those who have worked on the same, they must know that this version requires us to create a ‘recognizer’ which depends on the location and model that we want to transcribe the language with. For a lot of languages, we have the global location. For some languages, global is not supported. Some examples are: bn-IN and yue-Hant-HK.

Let’s pick two languages, yue-Hant-HK and en-US:

• en-US has a global long recognizer. yue-Hant-HK has a us-central1 chirp recognizer.

Now, I created a speech client for the two languages as follows:
For en-US:

this.speechClient = new SpeechClient({
    keyFilename: <path to service account file>
    projectId: <project id>,
});

For yue-Hant-HK, I add a apiEndpoint: "us-central1-speech.googleapis.com", otherwise it doesn’t work.

Then I perform streaming recognition on the input audio. For en-US it works. But for yue-Hant-HK, I get the following error:

}

Can someone help with the same?

I even went ahead and gave the service account file owner permissions but still gives the same error.
