What it does
π Description This workflow allows users to ask questions about past meetings using their voice. It converts the voice question into text, searches stored meeting notes using Pinecone, and replies with a spoken answer generated by AI. It helps teams quickly recall decisions, tasks, and discussions without reading long meeting notes. π§ π π What This Template Does 1οΈβ£ Receives a voice question through a webhook endpoint. π 2οΈβ£ Converts the audio question into text using speech transcription. π€β‘οΈπ 3οΈβ£ Cleans and prepares the question for searching. β
4οΈβ£ Converts the question into an embedding for semantic search. π 5οΈβ£ Searches relevant meeting notes from Pinecone using the team namespace. π 6οΈβ£ Combines retrieved meeting context into a single readable format. π§© 7οΈβ£ Uses AI to answer the question strictly from the meeting context. π€ 8οΈβ£ Converts the AIβs text answer into spoken audio. π 9οΈβ£ Sends the audio response back to the user via webhook. π β Key Benefits β
