How can I implement STT and let the uploader write on my Microsoft Azure container?

Problem:

The main problem is identifying the right Microsoft Azure components and then integrating them into the current Agora Speech-to-Text start request payload. The goal is to successfully upload a .vtt file into the MS Azure container after every STT stop request.

Solution:

Step 1: Create a storage account using MS Azure dashboard and save as your accessKey. 

Step 2: Click the newly created storage account and navigate into its main menu and select Security + networking tab, then Access keys. Save the key1 or key2 string values as your secretKey

Step 3: Also in the storage account main menu, please scroll down, open Data storage and select "Containers"

Step 4: Create a new "container" and save as your bucket name

Step 5: Use the saved credentials on the STT start request || captionConfig:

{
    "captionConfig": {
        "storage": {
            "accessKey": "{{AccessKey(Azure)}}",
            "secretKey": "{{SecretKey(Azure)}}",
            "bucket": "{{Bucket(Azure)}}",
            "vendor": 5,
            "region": 0,
            "fileNamePrefix": [
                "STT",
                "{{channelName}}"
            ]
        }
    }
}

Step 6: perform a full STT request lifecycle: acquire, start, query and stop then check if the .vtt files are uploaded into your bucket.
