Runtime APIs: Quick Reference
Summary of the main resources for using the gRPC APIs.
APIs
This section describes how to use gRPC APIs to interact with speech recognition, natural language understanding, dialog, and text‑to‑speech runtime services. It also describes how to access event logs generated by these services.
