OAuth authentication requirements for the Speech API

Authentication identifies who is making an API request, and authorization identifies what data the requester may access. OAuth is an industry standard for authorizing limited access to services and data. Applications must obtain a secure token that identifies the application that makes the request. The token is passed to the resource server (API server) with each API request. For more information, see Authenticate APIs with OAuth.
