Step 1: Provision a Cognitive Services resource
If you don't already have one in your subscription, you'll need to provision a Cognitive Services resource.
1. Open the Azure portal at https://portal.azure.com, and sign in using the Microsoft account associated with your Azure subscription.
2. Select the Create a resource button, search for cognitive services, and create a Cognitive Services resource with the following settings:
Subscription: Your Azure subscription
Resource group: Choose or create a resource group (if you are using a restricted subscription, you may not have permission to create a new resource group - use the one provided) Region: East US Azure region Name: caption12345678 Pricing tier: Free F0
3. Select the required checkboxes and create the resource.
Wait for deployment to complete, and then view the deployment details.
4. When the resource has been deployed, go to it and view its Keys and Endpoint page. You will need the endpoint and one of the keys from this page in the next procedure.
Step 2: Save Key and Endpoint values in Params.json
Open the configuration file, C:\Resources\Caption\Params.json. and update the configuration values it contains to reflect the endpoint and an authentication key for your cognitive services resource. Save your changes.
