Requirements
The node needs an OpenAI Api key to perform. To learn more about getting an API Key and finding it, you can refer to the OpenAI Api page .
After getting your API Key, you can learn about finding and securely using your key following the instructions on this page.
You can also see which models are available through the OpenAI Models page.
Project Structure
The node expects events from the SR Http or SR WebSocket node.
A minimum viable project that utilizes the Topic Detection node can be built as such:
Since the Topic Detection node only needs events from the SR nodes, it can be placed wherever an SR node is utilized. A more complicated project that utilizes Topic Detection can be built as such:
Detailed Workflow
Topic Detection node accumulates all the SR Milestone events it receives and waits for a Flush call. (eg. If the client is a Call Recorder application, Flush is typically sent at the end of a call.) When Topic Detection node receives a Flush, it detects the topic of text it had received so far with the help of OpenAI and raises a Topic Detected event.
Supported flow types
Stream, Batch
