This is the repository for the LinkedIn Learning course OpenAI Realtime API: Building Voice Agents with Realtime API and the Agents SDK. The full course is available from LinkedIn Learning.
Build voice-to-voice, text-to-voice, and image-to-voice AI agents with OpenAI’s Realtime API and the Agents SDK. In this course, you’ll explore how the Realtime API works, how to build realtime voice agent apps using the Agents SDK, and how to enable advanced features including guardrails, function calling, MCP servers, and live image input via device camera. You’ll also learn how to authenticate front-end apps using a custom auth server and ephemeral tokens.
See the readme file in the main branch for updated instructions and information.
This repository has branches for each of the videos in the course. You can use the branch pop up menu in github to switch to a specific branch and take a look at the course at that stage, or you can add /tree/BRANCH_NAME to the URL to go to the branch you want to access.
The branches are structured to correspond to the videos in the course. The naming convention is CHAPTER#_MOVIE#. As an example, the branch named 02_03 corresponds to the second chapter and the third video in that chapter.
Some branches will have a beginning and an end state. These are marked with the letters b for "beginning" and e for "end". The b branch contains the code as it is at the beginning of the movie. The e branch contains the code as it is at the end of the movie. The main branch holds the final state of the code when in the course.
