An Azure service that integrates speech processing into apps and services.
anonymous userrasad The API that you are referring to is the Azure speech service speech studio API to create a project, train a custom model and deploy it for evaluation.
This is actually the customization feature of the service for scenarios where a customer or a business has unique requirements to adhere to and the out of the box REST API of the azure speech service does not meet their criteria.
If you are new to Azure speech service then I would advise you to start off with some basic scenarios or try out the quickstarts that are mentioned in the documentation. If you need guided help to use the service then MS learn module to use the speech API is the best place to get started. I hope this helps.
