Obtain subscription keys

To get started using the Azure Custom Speech Service, you first need to link your user account to an Azure subscription. Subscriptions to free and paid tiers are available. For information about the tiers, see the pricing page.

Get a subscription key

  1. You can get a subscription key from the Azure portal in one of two ways:

    • Go to the Azure portal, and add a new Cognitive Services API by searching for Cognitive Services and then selecting Cognitive Services APIs.

    • Or go directly to the Cognitive Services APIs.

    b. Subscription. Select one from your Azure subscriptions.

    c. API type. Select Custom Speech Service (Preview).

    d. Location. It's currently West US.

    e. Pricing tier. Select the tier that works for you. F0 is the free tier. The quotas that are allowed are explained on the pricing page.
